FIELD: lubricants.
SUBSTANCE: invention relates to lubricating compositions for the preservation of tractor and combine engines when they are put into off-season storage. A protective lubricant composition is described, including base oil, gun grease and rapeseed oil as inhibitory additives, characterized in that purified spent mineral engine oil is used as the base oil, rapeseed oil is polymerized at a temperature of 140-150°C for 8-10 hours, the components of the composition are taken in the following ratios, wt. %: purified spent mineral engine oil 80-90, polymerized rapeseed oil 5-10, gun grease 5-10.
EFFECT: proposed composition has high performance characteristics and can perform the functions of a working and preservation lubricant for a short time when performing an operation during the installation and removal from storage of agricultural machinery.
