E-10 in everything, boat, car, lawn equipment. Only exception is my Polaris 570 4 wheeler. They recommend non ethanol. Also, in reply to eagle 1's comment. I also used walmart oil in several boats( I have owned 13 with mercs, johnsons, evenrudes and yamahas. ) and it has the same specs as the rest. It is not made by walmart. Some oil companies market off brands. Some convenience stores use different brands of gasoline, depending on best deal for them, with or without ethanol.
