Fuel?

I run standard unleaded with NO ethenal and Quickleen. Would I get better performance out of my 225 Optimax if I used higher octane with ethenal or am I putting the correct fuel in?

Thanks.

Run 87 octane. Also run quickcleen and marine stabil in every tank. You will not see any performance enhancements with higher octane. You will be just spending even more money. It can actually hurt your motor.

Perfect, that is what I thought. Thanks.
