    Abstract: A method of operating a marine or stationary diesel engine is disclosed in which the engine is lubricated with a single cylinder lubricant that is fed at a substantially constant feed rate to the engine. When the engine runs on fuel having a sulphur level that requires more base than is available from the cylinder lubricant, at least one overbased detergent having a base number of greater than 150 mgKOH/g is added to the fuel.
