    IMPORTANT: If you use gasoline that contains or might contain alcohol, you must increase the frequency of inspection for leaks and abnormalities. IMPORTANT: When operating a Mercury MerCruiser engine on gasoline containing alcohol, storage of gasoline in the fuel tank for long periods should be avoided. Long periods of storage, common to boats, create unique problems.
