Claims
- 1. A method of lubricating a two-cycle engine which consists of
- a) mixing
- (A) 60-95% by weight of an ester of a hindered alcohol with a straight-chain saturated fatty acid having 8-12 carbon atoms with
- (B) 5-40% by weight of a complex ester of a hindered alcohol with a straight-chain saturated fatty acid having 8-12 carbon atoms and also with a dibasic acid having 20-50 carbon atoms to obtain a mixture and
- b) applying said mixture to said two-cycle engine.
- 2. A method of lubricating a two-cycle engine which consists of
- a) mixing
- (A) 60-95% by weight of an ester of a hindered alcohol with a straight-chain saturated fatty acid having 8-12 carbon atoms with
- (B) 5-40% by weight of a complex ester of a hindered alcohol with a straight-chain saturated fatty acid having 8-12 carbon atoms and also with a dibasic acid having 20-50 carbon atoms, and with
- (C) up to 30 parts by weight of a hydrocarbon based solvent and/or a lubricating based oil and
- b) applying said mixture to said two-cycle engine.
- 3. The method according to claim 1 wherein said mixture exhibits a kinematic viscosity of 6-15 mm.sup.2 /s at the temperature of 100.degree. C.
- 4. The method according to claim 2 wherein said mixture exhibits a kinematic viscosity of 6-15 mm.sup.2 /s at the temperature of 100.degree. C.
- 5. The method according to claim 1 wherein said component ( B ) has the formula hereinbelow ##STR2## wherein X.sup.1 to X.sup.4 are identical or different from each other and each of X.sup.1 to X.sup.4 is an alkyl group having 1-4 carbon atoms or a group having the --CH.sub.2 --OCO--R.sup.4 wherein R.sup.4 is an alkyl group having 7-11 carbon atoms, R.sup.1 is an alkylene or alkenylene group having 18-48 carbon atoms, R.sup.2 to R.sup.4 are identical or different from each other and each of R.sup.2 to R.sup.4 is a straight-chain alkyl group having 7-11 carbon atoms.
- 6. The method according to claim 2 wherein said component (B) has the formula hereinbelow ##STR3## wherein X.sup.1 to X.sup.4 are identical or different from each other and each of X.sup.1 to X.sup.4 is an alkyl group having 1-4 atoms or a group having the --CH.sub.2 --OCO--R.sup.4 wherein R.sup.4 is an alkyl group having 7-11 carbon atoms, R.sup.1 is an alkylene or alkenylene group having 18-48 carbon atoms, R.sup.2 to R.sup.4 are identical or different from each other and each of R.sup.2 to R.sup.4 is a straight-chain alkyl group having 7-11 carbon atoms.
- 7. The method according to claim 1 wherein said hindered alcohol is an alcohol having the carbon atom in the .beta. position a quaternary carbon atom.
- 8. The method according to claim 2 wherein said hindered alcohol is an alcohol having the carbon atom in the .beta. position a quaternary carbon atom.
