I was talking to a friend of mine who owned a turbo diesel, I just got back of vacation and was pulling my boat (10,000 lb), at 2200 RPM I began to get a miss in the engine. He told me that it sounded like the injectors and that he used to pour the fuel filter canister half full of ATF when changing the filter to clean the injectors, he said it smoked some initially but he never had any injector problems after 300,000 miles. Has anyone tried this and could it damage anything?
