The fluid for use in the transmission, like motor oil, is made on different bases. Producers specify the composition of their oil-mineral, synthetic, or semi-synthetic in the product specifications. Are the bases for the use of transmissive oil available? Oil composition of the composition of the
Oil composition of the composition of the
Mineral transmissive oil is made of petroleum products, synthetic-by synthesis, and semi-synthetic is derived by mixing mineral and synthetic basis. In addition to the basics, different additives are added to the oil.
The most important parameter of transmissive oil is viscosity
The manufacturers claim that it is important to pay attention to viscosity when choosing a transmissive oil-this is the most important parameter, as well as the composition of the additive. The additives are responsible for the long life of the details: antioxidizing, anti-oxidation, anti-corrosive, anti-foam, etc.
Basics of transmissive oil
Mineral and synthetic bases have advantages and disadvantages.
The mineral base is capable of providing the best lubricating lubricating. In addition, the mineral base better formed a solid linen in high pressure conditions.
The ability of synthetic components in film formation is much lower than that of mineral oil. It is also considered that the additives are much more effective in the mineral base: they are better dissolved. For transmissions, where it is very important to prevent strong friction of parts, mineral oil is better. As the anti-friction additive (reducing friction), it is best to be exposed on a mineral basis.
The best features are completely synthetic oil
The synthetic basis is good that the highest viscosity index can be obtained by using only synthetic components. Synthetic oils can therefore be applied in a larger temperature range. Synthetic oils are less prone to "aging" (in this case oxidation), so their lifetime is much longer than that of mineral oil. The synthetic transmissive liquids are recommended to be used in those transmissions with high loads and high turnover, which are not sufficient for the mineral in this case.
The half-interactive basis is different in that synthetic components improve the mineral properties. At the same time, it would be much cheaper to have such transmissisive oil. About the transmissive oil additives
About the transmissive oil additives
The additives are very important in the transmission fluids, and their presence and the level of exposure in the oil is partly reflected in the API (GL) classification. This classification is developed by American experts and divides oils by 5 types in operational properties. Russia's GOST 17479.2-85 (TM) is practically identical with it.
International and Russian oil classifications are almost identical
GLE-1 or PM-1 means pure mineral oil in which additives are not present, or there are antioxidative and anti-oxidative additives.
GL-2 or TM2 is a type of oils, the main additives in which are antifriction.
GL-3 or TL-3 is the type of oils, where special attention is given to antizadditive additives, usually their number is up to 2.5%.
GL-4 or TL-4-in such oils also the contrazative components of the average activity have been added, but their number is already much higher-up to 4%. There is also a need for the unbearable additives.
G-5 or TL-5. Added high activity antizadditive additives, up to 6%.
GL-6 or TL-6. They have the highest percentage of contraadditive additives and other multifunctional additives.
Can I mix the mineralco and the synthetics?
Mixing of oil on different bases results in deterioration of oil properties. Often the motorists mix the transmissioner with the existence of a half-synthetic oil, where the addition of synthetics to the mineralka is beneficial both to the oil and to the transmission.
But it is necessary to take into account that this blending is so blended and it is impossible to make such a mixture in the living conditions. Plus, there are additives in oils that provide the correct oil properties, and if they are blended, they will not work correctly. The best thing that can happen is that the transmission of the transmission will be reduced, and the energy and fuel will be spent more. At worst, a rapid failure of the details of the transmission is possible.
