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. In cars alcohol‑blend fuels
normally are consumed before they can absorb enough moisture to cause trouble, but
boats often sit idle long enough for phase separation to take place. In addition, internal
corrosion may take place during storage if alcohol has washed protective oil films from
internal components.

strongly recommend the use of the following oils listed in the order of recommendation:
