LUBRICANT OR FUEL COMPOSITION COMPRISING AN AMIDE AS FRICTION-REDUCING ADDITIVE
Document Type and Number:
WIPO Patent Application WO2003031543
Kind Code:
A3
Abstract:
The invention relates to lubricant compositions based on a base oil and a friction-reducing additive comprising a saturated aliphatic amide having a carbon chain length from 10 to 24 carbon atoms. The friction-reducing additive can also further comprise an ester or aliphatic amine. The friction-reducing additives provide enhanced oxidative stability, as compared to commercially available friction-reducing additives, in engine oils, fuels and transmission oils.
