Been hearing a lot of talk about E-85 where I live... Sounds like it will happen soon in Eastern KY. Where I fish mostly though ethanol free 87 and 89 octane fuel is available. If I understand correctly 91 octane is the min octane fuel that I can run safely in my 250 HPDI Phase III motor without the risk of burning a piston. Since I bought the boat in August I have been running E-10 92-93 octane fuel with Stabil Marine formula and Ring Free. I also have a 10 micron filter installed. What can I do if E-85 becomes the only 92-93 octane fuel available?![]()
