NANOPROTEC protective coatings are applied by spraying from aerosol cans. Do not require any preliminary preparation of the treated surface.Any of the compounds is effective even when the untreated parts are already wet.The composition is applied directly to surfaces that need to be protected from moisture or which need to be waterproofed.
What are NANOPROTEC Protective Composites intended for and why are they recommended to be used?
NANOPROTEC Protective Composites are designed to restore worn friction surfaces and optimize gaps in mating pairs of friction units of various mechanisms. They are used in the standard operating conditions of cars and mechanisms using their lubrication system and their regular lubricants (oils) as carriers of NANOPROTEC Protective Composites to the contact points of rubbing surfaces. At its core, they protect rubbing surfaces from wear, scuffing, tacking and increase the service life of mechanisms several times.
What determines the antifreeze colour?
The colour of antifreeze depends solely on dyes added to the coolant. They carry no functional load and serve only as markers used to distinguish liquids. So they are easier to identify. The fluid must be selected not by colour but by tolerances and manufacturer’s recommendations.
What is the advantage of NANOPROTEC ANTIRAIN glass protection?
The composition has no expiration date, is easy to use and most effective: it does not glare in the headlights of oncoming cars, does not leave film, stains, increases driving comfort at night, cannot be erased by wipers or damaged during wash, and also does not require frequent repeated application. One application lasts an average of 10 months or 20,000 km.
What is the difference between synthetic, semi-synthetic and mineral oil?
Oils based on an exclusively mineral basis are most often used in engines manufactured earlier, as well as in obsolete models that consume large quantities of oil. Nevertheless, NANOPROTEC mineral oils are created on raw materials of exceptional quality and able to surprise even the most demanding customers with their properties. Semi-synthetic — we have achieved the great balance between mineral water and synthetics. Approximately 30~50% of the synthetic component can give the oil much more stability during engine operation in different climatic conditions, as well as during overheating and cold start of the engine. Such oils are most suitable for high-mileage engines, when the burns increase. NANOPROTEC semi-synthetic oils have exceptional lubricating and protective properties, reducing waste and prolonging engine life. Synthetic oils are equally well proven in operation in both winter and summer. Improved properties, stable performance, the longest service life. These oils are most stable at low temperatures (<-15 ºС), retain their properties longer and are perfect for extended drain intervals. NANOPROTEC synthetic oils are superior in performance to similar oils from other manufacturers and demonstrate excellent properties even in the most extreme operating conditions.
Can antifreezes of different colours be mixed together?
No, it is not recommended. Different packages of additives that are part of antifreeze may conflict with each other. Also not recommended to mix coolants from different manufacturers.
How does the composite work?
After spraying, a protective film forms on the surface, even if the workpieces are already wet. NANOPROTEC provides a 100% water replacement rate within 10 seconds, which means that the composite penetrates the water, displacing and replacing it. As a result of high adhesion and low internal friction, NANOPROTEC sequentially forms a protective water-repellent film under water.Thus, these protective compositions are superior to any other product in all tests for protection against moisture and corrosion.
How to choose the right viscosity of oil suitable for the engine of my car?
The primary source for choosing the oil are manufacturer’s recommendations. Warranty cars are serviced at specialized service stations, the best place to find out about recommended oils. It should be noted right away that the manufacturer’s recommendations are intended only for new engines operating in conditions close to ideal. That is why oil for automobiles is often selected based on real temperature conditions and the state of a particular engine. It is important to pay attention to the tolerances indicated on the oil packaging. They will tell you whether the manufacturer of a particular car brand recommends using this oil in the engine.NANOPROTEC oils meet the high requirements of the modern automotive industry and have the recommended tolerances of most automakers, so you can choose the oil for almost any car and machinery.
What are NANOPROTEC Protective Composites made of? Can their composition not be suitable for a car oil and have a negative effect on the engine or the treating piece?
Basically, the compositions consist of balanced combinations of specially ground minerals of the layered silicates group (serpentines, chlorites, etc.). In addition to minerals, NANOPROTEC contains 99.5-95% of a carrier, i.e. yellow untreated mineral oil. The chemical composition and preparation technology of NANOPROTEC Protective Compositions in their modern version are the result of 20 years of scientific research and continue to be improved to increase their efficiency and due to changes in designs and working conditions of friction units. The compositions are carefully selected for each friction unit and tested in the laboratory on a friction machine and a bearing stand. Quality control is carried out after the production of each batch and is carried out in the process of operation by consumers. This approach eliminates the negative impact of NANOPROTEC Protective Compositions on components and mechanisms, subject to all recommendations. Over the entire period of Nanoprotec existence, there has been no recorded case of a negative effect of protective compositions on the machined units. Each client can consult with our experts on the selection of treating schemes, and in case of difficulties during operation, we are always happy to help and answer all questions.
When should you not use NANOPROTEC ANTIRAIN?
You cannot apply the composition to the surface of glasses that have mechanical damage: chips, cracks, scuffs, scratches. If the glass has obvious damage, a kaleidoscope effect, glare, or image distortion may occur after applying the product. That is why we recommend to apply the product on a flat glass surface, without chips, cracks, scuffs. Be sure to pay attention to this and check the glass condition before applying, especially if the vehicle’s mileage exceeds 100,000 km.Not recommended:- Apply nanocosmetics in rooms with a temperature regime that does not comply with the instructions.- Apply nanocosmetics in rooms with relative humidity that does not comply with the instructions.- Apply nanocosmetics in rooms with dusty air that does not comply with the instructions.- Apply nanocosmetics on surfaces not previously cleaned with special means.- Apply nanocosmetics on surfaces not previously degreased with special agents.
Are NANOPROTEC Protective Compositions additives?
Calling NANOPROTEC™ protective compositions as additives is not entirely correct. NANOPROTEC Protective Compositions are triboengeneering compounds, which now are the most neutral automotive chemicals of the latest generation. This technology uses the unique properties of natural minerals to restore worn-out friction units of used engines, gearboxes, and other vehicle components and industrial facilities. NANOPROTEC technology also allows you to optimize the contact parameters of rubbing pairs of parts, which leads to improved technical parameters up to nominal and higher. According to the functional purpose, the protective compositions belong to the class of anti-friction (reduction of friction losses), anti-wear (decrease in wear rate) and anti-seize (increase in the maximum load setting surface of friction) additional additives in lubricants.
Do I need to flush the cooling system when changing antifreeze?
In this case, more attention should be paid to the colour of the old antifreeze and its transparency. If it is clean, and antifreeze of the same colour is poured, then flushing is not necessary; if it is a suspension with particles of oxides or flakes, then flushing the cooling system is necessary.
How often do I need to change the oil?
Recommendations on the timing of vehicle maintenance are given by the car manufacturer. But there are still averaged data available. Mineral oils should be changed after 5,000 km. Semi-synthetic, approximately after 7,000~10,000 km. Synthetic oils can work out 10,000~15,000 km. But you should still monitor the oil level in the engine and its cleanliness level. It is worth paying attention that only synthetics are suitable for extended oil change intervals. In semi-synthetic oil, do not exceed more than 10,000 km mileage between maintenances. It is also important to consider the operating conditions of the vehicle. Focusing on mileage alone is not enough, machine hours and engine operating conditions are important. For example, if every 1,000 km equal 15~17 machine hours, as when driving without traffics jams and at low speed, then oil is capable of working out its maximum. Another thing is to gain a thousand kilometres in 7~10 machine hours: Despite the short oil life, high speeds and high loads accelerate burnup of additives. And the third option is urban, when thousand kilometres require over 55~60 machine hours. In addition to the huge oil life, the conditions are far from optimal: though the loads are small, frequent warm-ups, unsteady conditions, idling and other difficulties in operating the car in urban conditions contribute to the most significant flow of gasoline and condensate into the oil. NANOPROTEC engine oils have proven themselves under a wide variety of operating conditions. It is proven by the use of oils in motorsport in a wide variety of disciplines: from explosive drift and stable, high-speed rally to overloaded desert conditions and rough terrain in rally-raids. For perfect engine protection under any operating conditions, we recommend the use of NANOPROTEC Protective Compositions.
What is the difference between NANOPROTEC and other insulating sprays?
Unlike well-known insulating sprays from other manufacturers, NANOPROTEC grease is resistant to strong mechanical stresses, does not absorb moisture, does not contain isopropanol, ethylene glycol and white spirit, does not evaporate, does not require additional washing and lubrication of nodes after applying the product.While displacing moisture, NANOPROTEC lubricates the treated mechanisms.
Can different types of oils be mixed together? Can I add NANOPROTEC oil to oils from other manufacturers?
Obviously, it is not advisable to mix different types of oils, such as synthetics and mineral oils, just as you should not mix oils of different viscosities. The reason for this is simple — different oils contain different packages of additives, and nobody knows how they will interact with each other. Therefore, it is better not to risk mixing different types of oil. It is possible to add NANOPROTEC oil to oils of other manufacturers, but you should note that Nanoprotec oils are made on a high-quality basis with the addition of a modern, innovative additive package, and they exhibit their properties best when used solo. Convenient packaging of 4 litres and 1 litre allows you to always have some filling-up on hand and avoid unpleasant situations when you have to look for an alternative brand product of dubious quality.
How does the composition affect plastic, glass, rubber?
NANOPROTEC Protective Compositions are absolutely safe for all surfaces. They do not react and do not destroy plastic, glass and rubber surfaces. If the excess composition was used during treatment, after 10 minutes of exposure to the treated nodes and surfaces, it is enough to simply wipe the excess agent with a napkin.
How often do I need to change antifreeze?
The antifreeze change period is prescribed by the automaker. It is often recommended to change the coolant once every two years, but sometimes an earlier change is required. Deterioration of antifreeze quality is especially intense when exhaust gases leak into the cooling system through the defects of the mains or air is sucked in. Therefore you need to check the places of possible fluid leaks more often, as well as the condition and mounting of the hoses.Not recommended:- Use coolants that do not comply with the recommendations of the vehicle manufacturer.- Increase the coolant change interval recommended by the vehicle manufacturer.- Change the coolant less than once every 2 years.- Mix coolants with different tolerances.- Mix coolants from different manufacturers.- Change coolants without the use of personal protective equipment.
Is it possible to use NANOPROTEC Protective Compositions in a new engine or assembly?
Not only possible, but highly recommended. In areas of friction in the minimum-mileage engine, the so-called new, a protective layer is also formed, and despite the fact that the gaps were okay anyway, there is a decrease in friction losses, i.e. increase in mechanical efficiency due to the antifriction properties of this layer. As a result, fuel consumption is reduced, engine power and throttle response are increased. But the most important thing is that for absolutely all engines, regardless of mileage, a several-fold increase in resource is typical; it means that you can significantly postpone the next major overhaul. How much? Depends on the conditions and operating mode of the car or unit.
How long does the waterproofing effect last?
The guaranteed effect after treatment with protective compositions is at least 1 year in normal operation.
Is it necessary to use flushing oil when switching from oils of other brands to NANOPROTEC oil?
It is important to understand that when replacing oil, an insignificant amount of it still remains in the engine and oil system — about 5~10%. In order to avoid mixing it with fresh oil, especially if oil from another manufacturer was previously filled, flushing oil is recommended. It will remove residual used oil, as well as washed dirt and soot particles, and perfectly prepare the engine for filling fresh NANOPROTEC oil.
Is it possible to achieve the new-treated effect for parts with constant use of protective composites? So to avoid overhaul at all?
It all depends on what exactly you are treating and in what condition the unit or mechanism is then operated. But you must remember that the use of protective compositoins is aimed at improving operational properties and increasing the resource. With the right treating scheme, you can achieve an increase in resource up to 5 times.
Does NANOPROTEC oil include NANOPROTEC Protective Compositions?
No, it doesn’t. The oil is made from high-quality raw materials and contains a standard additive package. It has unique protective and lubricating properties, demonstrating excellent temperature stability. At the same time, it is ideally matched for use with NANOPROTEC Protective Compositions. This oil is a perfect base for our protective compounds, and their combined use gives the most effective, tangible and quick effect.Not recommended:- Use oil with tolerances that do not meet the requirements of the vehicle manufacturer.- Increase the oil and lubricant change interval recommended by the vehicle manufacturer.- Change engine oil less than 1 time per year (or according to the manufacturer recommendations).- Change gear oils less than once every 2 years (or according to the manufacturer recommendations).- Mix engine oils of various viscosities.- Mix engine oils from different manufacturers.- Mix transmission oils of various viscosities.- Mix transmission oils from different manufacturers.- Change oil without using personal protective equipment.
I saw in the advertisement how a drill works underwater after treatment, is that true?
Yes, it is. For advertising purposes, a wide variety of electrical devices were used to demonstrate the waterproofing effect. But this does not mean that the treated tool can be used under water on an ongoing basis. The main function of NANOPROTEС compositions is to protect surfaces and components from natural environmental factors, as well as force majeure circumstances. All treated tools and electrical appliances are recommended for use as intended, taking into account the recommendations of the manufacturer.
If I use high-quality engine or transmission oil, why should I add anything else if the oil already contains an additive set?
The differences between NANOPROTEC Protective Compositions and the standard additive package in oil are as follows:1. They can restore friction surfaces (form a protective layer up to 15 microns thick) and optimize the geometry of friction surfaces.2. The protective layers have an increased oil-holding ability — the protective layer holds the oil on the surface much better than the untreated surface itself, which turn the usual friction into semi-fluid or hydrodynamic friction (the “oil wedge”).3. The aftereffect is the ability to maintain friction parameters even after changing the oil until the protective layer is completely worn out. The layer wear rate in the assembly is 1.5~3 times lower than that of the initial metal at the complete absence of the Nanoprotec compound (abrasive and corrosive wear, depending on the assembly operating condition).4. Chemically neutral to all substances included in the lubricant additive package, and to the lubricant itself, which ensures the safety of use in any components and mechanisms (subject to the user instructions).
Is it possible to use NANOPROTEC SUPER ANTICOR as an anti-corrosion agent on large areas, for example, for removing rust from fences and preparing them for painting?
We do not recommend such experiments. The compositions are intended primarily for protection against moisture, which can lead to corrosion. The component penetrating under the rust layer is optional; it prepares the surface for exposure to the main, water-repellent protective composition. When applied to a surface, it protects it from the occurrence of many types of corrosion in the future. All types of surfaces that are recommended to be treated are indicated on the packaging.
What is ACEA?
ACEA (Association des Constructeurs Européens de I`Automobile) is the Association of European Automobile Manufacturers, founded in 1991. The Association represents the interests of 15 different European manufacturers of cars, trucks and buses at the EU level. Members include manufacturers such as BMW, Scania, Volkswagen, MAN, Volvo, etc. In addition, ACEA also includes representatives of additive suppliers and lubricant manufacturers who select test methods and engines for the specification. The organization is developing ACEA specifications and use mainly engines from European manufacturers for tests. ACEA specifications combine the laboratory and technical requirements of various European vehicle manufacturers for oils. The specifications also define the basic requirements for engine cleanliness, resistance to ageing, wear protection, fuel consumption and emission of pollutants. To ensure a constant increase in the quality of engine oils, ACEA began to use the new ACEA classes in December 2010. The ACEA classification published in 2010 defines the minimum requirements of all European manufacturers of vehicles and engines:- ACEA A/B, ACEA C — oils for gasoline and diesel car engines;- ACEA E — oils for powerful diesel engines.
Where are NANOPROTEC Protective Compositions used?
Fields of protective compositions application are divided into 2 groups: 1. motor vehicles and special equipment;2. industrial application.The first group includes all types of cars and trucks, heavy and special equipment. Namely, such components and assemblies as: - Internal combustion engines of all types and sizes, diesel generators;- Rolling and sliding bearings, constant velocity joints;- Automatic transmission and manual transmission, gearboxes;- High pressure fuel pumps;- Hydraulic units and power steering.Fields of technology application in industry:- All types of transport enterprises;- Heavy and special equipment;- Diesel engines (including rail and sea transport), diesel generators;- Machine park of enterprises;- Piston and screw compressors;- Gearboxes, multipliers, gears;- Rolling and sliding bearings;- Hydraulic systems, hoists, presses, actuators, manipulators;- Gears, guides and other mechanisms lubricated with greases.
In order to treat your car with NANOPROTEC Protective Compositions, do you need to go to a service station?
Most protective compositions are designed for use by drivers themselves. You should carefully read the instructions and follow them when treating the car by yourself. Before starting the full treatment, we recommend you to contact the company’s specialists for advice on the proper selection of the protective compound and the treating scheme for a particular car or unit. Important! Before using NANOPROTEC Protective Compositions, make sure that there is sediment at the bottom of the bottle — this is the active substance. Thoroughly stir the contents in the bottle until a homogeneous substance is obtained (until the active working component, the precipitate, is fully mixed). The step-by-step treating scheme for each product is described in detail in the instructions.
What is API?
API is an American Petroleum Institute that issues API classifications common in the US and Asia. The publication of API classifications is similar to the issuance of ACEA specifications. The institute mainly uses engines of American manufacturers for tests.The API classification system divides engine oils into only two groups:• API S — oils for gasoline engines;• API C — oils for diesel engine.The API class designation usually consists of two letters: the first indicates the engine oil type, and the second, compliance with a specific quality standard. The farther from the beginning of the alphabet the second letter is, the higher the quality of the oil. For example, API SJ is the oil of lower quality than API SM. US engine manufacturers do not require alternatives to ACEA A and B classes because they do not produce high-speed diesel engines for cars — diesel cars are not popular in the US.API standards are regularly supplemented and tightened, and the second letter of the classification essentially shows what quality requirements the oil meets, and also in which yearthese requirements were valid.
What is the difference between NANOPROTEC SUPER LUBRICANT and other lubricants on the world market?
NANOPROTEC SUPER LUBRICANT is a unique lubricant that has no analogues in both composition and principle of action. Often, conventional lubricants contain a solvent, carbon dioxide, inert ingredients and mineral oil. This composition provides a short-term effect on the treated surfaces and little protection against moisture. NANOPROTEC SUPER LUBRICANT, containing nanoformula, completely displaces moisture, protects against corrosion and perfectly lubricates treated surfaces for at least one year. In addition, not a single lubricant in the world works in such a temperature range — -80 °C to 140 °C.NANOPROTEC SUPER LUBRICANT has excellent penetrating ability, which greatly facilitates the unwinding of various rusted fasteners, threaded joints and parts that simply stuck to each other. It has a wide application range: From professional in all types of service and industry to household — for lubricating creaking door hinges, etc.Not recommended:- Use protective aerosols on live electrical equipment.- Use protective aerosols near open flames.
JASO is a specification and quality mark for motorcycle engine oils. JASO quality classes are divided into groups: M, which requirements apply to four-stroke engine oils, and F, which applies to two-stroke engine oils. The M oils, in turn, are divided into oils of categories MA and MB, which differ in the value of the coefficient of friction created in the lubricated clutch. MA oils are defined by a high friction coefficient. They do not pose a problem in high-torque motorcycle engines with a relatively small clutch and perfect for clutch applications. The MB class includes oils that do not achieve a sufficiently high friction coefficient while meeting all the other criteria of the JASO specification. They are only limitedly applicable in motorcycles with a “sensitive grip”. The highest engine oil requirements for four-stroke engines are currently defined by the JASO MA-2 standard. This quality class means even higher friction coefficients in the clutch and, therefore, maximum compatibility with clutches, even in case of engines with ultra-high torque.Low SAPSThe abbreviation is formed from the first letters of the words Sulphated Ash, Phosphorus and Sulphur. Therefore, a low SAPS engine oil is an oil with the low level of sulphate ash, phosphorus, and sulphur. Since these oils form little ash, they are also called low ash oils. The use of low SAPS engine oils is precisely what modern vehicles require.Mid SAPSThe abbreviation is the same, and “mid” stands for “middle”. Thus, mid SAPS engine oils are defined by the average level of sulphate ash, phosphorus and sulphur.
Why in some cases it is not recommended to use NANOPROTEC Protective Compositions?
Protective compositions are not recommended if some parts and assemblies have mechanical damage. It is important to understand that protective compositions will not cause additional harm to the mechanism, but they will not be able to “repair” it either. If you know about mechanical damage to nodes, you better contact the service station to replace or repair them, and only after that treat this node to protect it in future operation. It is also not recommended to use NANOPROTEC Protective Compositions if friction surfaces wear level is critical: in this case, the composite will not be able to “build up” the protective layer to nominal values.
What is SAE?
SAE (Society of Automotive Engineers) is an organization that has developed viscosity grades indicating fluidity of oils for four-stroke engines. Viscosity classes indicate fluidity of the oil and its dependence on temperature, but are not directly related to the oil quality. The first digit, usually followed by the letter W, indicates the fluidity of the oil at low temperatures, i.e. the so-called winter viscosity. The second figure shows the property of the oil to maintain sufficient density at high temperatures, that is, the viscosity of the oil at 100 °C. The lower the winter class number (SAE 0W, 5W, 10W, etc.), the lower the temperature at which the oil retains its liquid condition — this protects a cold engine and facilitates its start. The higher the summer class number (SAE 30, 40, 50, etc.), the higher the viscosity of the oil at 100 degrees and the better it can protect the engine under extreme operating conditions.Most engines are designed to operate on oils of viscosity grade SAE 10W-40, which is sufficient at temperatures from -25 to +40 degrees. Given the climatic conditions of our region, the most common engine oils are SAE 5W-30; 5W-40 and 10W-40.
Which oils cannot be added to NANOPROTEC Protective Compositions?
Protective compositions are compatible with any type of engine oil and do not change their properties. But at the same time, Nanoprotec recommends the use of NANOPROTEC motor and transmission oils, as they are a perfect base for protective compositions, and their combined use provides for faster and more positive dynamics.
How quickly can I experience the effect of applying NANOPROTEC Protective Compositions?
Protective compositions begin to operate after several tens of kilometres. But everyone feels the effect in different ways. First of all, the detergent components included in the composition perfectly clean the surface before a new protective layer is formed. This can lead to increased gaps and create a feeling of deterioration in the operation of the mechanism or engine. This condition is normal, you can continue treatment according to the scheme. After the second stage of treatment, each driver feels a significant difference in the mechanism operation.Not recommended:- Use protective compositions in an unheated unit.- Use protective compositions without thoroughly mixing them first.- Use protective compositions for ICE at stage 2 without preliminary replacement of engine oil and filter element.- Stop the normal operation of the unit earlier than after 20-30 minutes after the direct use of protective compositions.- Use protective compositions in a faulty unit or assembly.
What is oil viscosity?
Viscosity is responsible for the oil ability to prevent wear of friction surfaces due to the formation of an oil film. Also, viscosity defines the fluidity of the oil at a certain temperature. Each oil has an individual viscosity-temperature dependence. Selected base oils and special additives can have effect on viscosity properties depending on temperature, for example, improve viscosity index (VI).HTHS viscosityIn modern all-season engine oils with VI improvers, viscosity depends not only on temperature, but also on pressure and shear rate. A shear rate is obtained by dividing the speed of a moving part (m/s) by the thickness of the oil film (m). To draw conclusions about the viscosity of the oil used, the term HTHS viscosity (High Temperature High Shear) has been used for some time.This parameter describes the oil behaviour in the lubrication hole at 150 °C and at a high shear rate, which is typical for high engine speeds. In order for multigrade engine oils with VI improvers to provide the necessary lubrication even at high temperatures and speeds, the HTHS viscosity limits are set in the ACEA C category. Engine oils with an HTHS viscosity of less than 3.5 MPa·s also help reduce fuel consumption, but they cannot be used in engines not designed for such oils.Viscosity indexThe viscosity index is a value that defines the dependence of viscosity on temperature: the higher the viscosity index, the less the fluidity of the oil depends on temperature, i.e. the better the oil withstands low and high temperatures. The viscosity index values of mineral oils are usually in the range of 90~110; for synthetic base oils, the viscosity index almost always exceeds 140. The higher the viscosity index, the less energy will be required when starting the engine cold or at low temperatures with the same nominal oil viscosity.
What is the flash point for oil?
The flash point indirectly defines the volatility of engine oil. It is the lowest temperature at which the fumes of the heated engine oil, under certain conditions, form a mixture with air that explodes when the flame breaks out (first flash). At flash point, engine oil is not yet ignited. The flash point is determined by heating the engine oil in an open or closed crucible. The results have different meanings; in a closed crucible, the flash point is lower by 20~25 °C.When choosing engine oil, you should be aware that the lower the flash point of the engine oil, the more it evaporates and burns on high-temperature surfaces, and also contaminates the engine with ash, soot and other combustion products. The engine oil that has a higher flash point is better. In modern engine oils, the flash point exceeds 200 °C, usually it is 210~230 °C and higher.
What is the fire point?
The engine oil fire point is the temperature at which the engine oil, when heated in an open crucible (Brenken’s method), ignites from the fire and burns for at least 5 seconds. The fire point of engine oils is higher than the flash point by at least 20~30 °C.The fire point is not a determining parameter in case of engine oils.
What is volatility?
Volatility is the property of the lightest fractions of engine oil to evaporate at high temperatures, which is expressed as a percentage of the loss from evaporation after heating the engine oil for one hour at 250 °C. To determine the volatility of engine oil, the Knock method is used. If 850 g of engine oil remains after heating 1,000 g at 250 °C for an hour, it means that its volatility is 15% (minus 150 g).In accordance with ACEA requirements, the volatility of motor oils of class A1/B1 must not exceed 15%; for oils of classes A3/B3, A3/B4, A5/B5, C1, C2, C3, E4, E6, E7, E9, this indicator should be less than or equal to 13%; and for oils of class C4, the volatility should be less than or equal to 11%. If the engine oil is too volatile, it will have to be poured into the engine more often, and therefore the oil consumption will be high.
What is the setting point?
The setting point is the temperature at which the oil ceases to be a liquid and solidifies. When cooled, the oil stops flowing under the influence of gravity. The setting point is often lower than the pour point by 3~5 °C. The solidification of the oil is due to the crystallization of the paraffins present in the base oil.When paraffin crystals are combined, the texture of the oil becomes firm and wax-like.
What is the pour point?
The pour point is the lowest temperature at which the oil still has the ability to flow. The pour point and the setting point define the physical properties of the lubricant at low temperatures.* “Mootoriõlid” by M. Naamsa was used as the supporting material.
