Abstract (en)
[origin: EP1138753A2] A lubricating oil composition used in air-cooled two-stroke cycle engines having a Mannich detergent and an ashless dispersant, wherein the ratio of the Mannich detergent to ashless dispersant is from 3:1 to 5:1. The detergency additive may also contain at least one of the following compounds: molybdenum, an overbased alkyl oxy benzene sulfonate and an alkylsalicylate. The detergency additive of the present invention provides improved detergency when used in a lubricating oil composition for air-cooled two-stroke cycle engines.
