225 Mercury Optimax

Use of non-Opti oil will void warranty. Find yourself a Merc repair facilty- they sell Opti oil in a 55 gallon drum- you bring a container and fill up - save yourself about $6 or 8 dollars over buying the one gallon containers at boating stores. The Opti oil has a dye in it which tells Merc if the proper oil has been used for warranty.
