Run it 50/50 100LL/marine gas so there is no ethanol. Lead is good stuff its a lubricant so the valves and rings love the stuff.
True but not necessary. Modern gas engines are designed to run on unleaded fuel. Unless you are running a high performance engine with high compression, you will be wasting your money; leaded fuel is expensive. If you are just trying to get away from the issues caused by ethanol, then just go with ethanol-free gas. Use this website to find the station nearest you.
