    Changing 2 stroke oil brand

    Hello, I’m wanting to switch brand of 2 stroke oil. It is a 2005 225Optimax. The previous owner used AmesOil brand and I would like to switch to Mercury Optimax oil due to having trouble finding the AmesOil product locally. What should I do to make sure I don’t kill my baby. She only has 160 original hours.
