Abstract (en)

[origin: EP1104800A2] The present invention relates to a lubricating oil composition for internal combustion engines, particularly gas engines utilizing gaseous fuel, such as natural gas or liquid propane gas. The lubricating oil composition of the present invention is useful in a method of improving the detergency and oxidation stability at elevated temperatures of gas engines. The lubricating oil composition comprises (a) a base oil, (b) a metal-containing detergent, (c) a boron-containing alkenyl- or alkylsuccinimide, (d) a zinc dialkyldithiophosphate, (e) an oxidation inhibitor and (f) an ashless dithiocarbamate.
