Abstract

A lubricating oil composition suitable for use in a low or medium speed diesel engine comprising a fuel oil with a residual oil content is characterised in that the lubricating oil composition further comprises a hydrocarbyl substituted amine or polyamine. The effect of such an amine is to reduce deposits due to the residual oil. A method of reducing deposits in a low or medium speed diesel engine is also disclosed.
