I need help determining what fuel to run in my new engine. The manual states that I should run a minimum of 91 octane ethanal free fuel. No such fuel is available anywhere in our state. I can get 87 octane ethanol free fuel, or I can get 91 octane with 10% ethanol. The manual says to use no less than 91 octane, but my dealer says its more important to use the ethanol free fuel. I'm looking for advice in the best fuel to use.
