Abstract: Stability of motor oil to oxidation when in contact with biofuel in diesel engine is studied. With the introduction of 5 % impurities in the form of biofuel in heavy-duty fuel engines significant changes in the properties of oxidized oils are not observed.
It is concluded that biodiesel fuel adversely affects thermal-oxidative stability of motoe oils for heavy duty engines; oil deteriorates such parameters as viscosity index; low-temperature degrades antiwear characteristics. To utilize this oil in diesel internal combustion engines, it is necessary to improve more active antioxidant additives, or increase their amount.

Abstract: This paper investigates the effect of viscosity modifiers on the low-temperature properties of alkylbenzene oils as well as the resistance of additives to mechanical destruction. It is shown that copolymers of ethylene and propylene as well as polyisobutylene are also effective viscosity modifiers for alkylbenzene oils, however they show inadequate resistance to mechanical degradation as compared with foreign counterparts

Abstract: The Russian fleet of vehicles with automatic transmission is growing very rapidly. In this regard, the task of developing oils for automatic transmissions based on domestic raw materials is becoming very urgent. We studied the low-viscosity base oils of API Group III to determine their applicability for automatic gear to meet present-day requirements. Comparative testing of ATF (automatic transmission fluid) samples showed that oils prepared using domestic LUKOIL VHVI 4 (isomerization product of wax concentrates) as a base oil are of high quality and can be used both in hydro-mechanical transmissions requiring oils of DEXRON®-VI level and stepless transmissions. At the same time the oils show highthermo-oxidative stability, excellent low temperature pumpability and excellent viscosity-temperature properties
