Ethanol free gas

I seen it said many times on BBC that its OK to mix but you should really run one or the other and not go back and forth.

This is a discussion we get in every couple of months, was the same way on the ATV forum I built.Some argue one way, others argue the opposite. Some swear by premium (which is near impossible to get eth. Free) some say 87 is fine and its a waste of money to buy premium. Ive heard mechanics say only buy name brand (Exxon, chevron, etc) gas for you boat motor b/c the detergents in it help keep your motor clean. They have said running cheap gas can cause power heads to blow. Still others will tell you gas is gas its all the same Exxon or mom and pop down the street.Honestly when it comes down to it. The answer is always the same. Run what you want. Its yours. If your motor likes it, And you dont mind paying for premium, use it. If your motor runs better on 87, use it. If you dont want to use eth gas go buy eth free. Regardless of what you put in it, additive is a must. Unfortunately there are way too many varying opinions on this subject. The very best advice I can give, is to look in your owners manual, and run what it says to run for your motor.

My boat was pre-ethanol and as such had old style lines and the ethanol had started gumming them up. I changed everything I could out and put a fuel separating filter system in. I have used non-ethanol fuel 90% of the time. In 2 years I have had a total of 1/4cup of water in the filter. What I worry about now is my fuel tank. Ive read that ethanol can soften the walls of pre-ethanol fuel cells. For all going to KABCOT there is a station near the lakes that sells 93 grade Ethanol free gas. I will say with 100% certainty that my boat runs much better on the E-free gas!
