Title:
HEAT-RESISTANT FUEL COST-SAVING TYPE ENGINE OIL
Document Type and Number:
Japanese Patent JP2005171186
Kind Code:
A
Abstract:
To provide a heat-resistant fuel cost-saving type engine oil that has high heat resistance, low viscosity, low vaporization loss and high friction reduction effect.
The heat-resistant fuel cost-saving type engine oil is prepared by adding a polymer mix in which MoDTC is bonded to a methacrylate-olefin copolymer in the molecule to a base oil of mineral oil or synthetic oil of ≥ 90 % saturated molecule fraction, ≤ 0.03 % sulfur content, ≥ 120 viscosity index, ≤ 5.5 mm2/s dynamic viscosity and ≤ 15 % vaporization loss.
