Abstract: This work investigates development of national oil for airscrew compressors with dialkylbenzene as a component that improves the viscosity-temperature properties. It was studied the effect of oils with dialkylbenzene on the basic compressor parameters. It was found that these oils could be an alternative to foreign counterparts

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
