I hear a lot of opinions on Ethenol. Now I have almost a full tank of fuel with E10 in a 30 gal. tank. There might be a couple months here in Texas that I can't get out on the water. After all it gets down to 50 or 60 degrees here. Anyway can I leave that fuel in the tank and engine with the Sta Bil or should I drain it and run it out of the engine too. I hear terrible things happen to your outboard with this E10 crap. What can you tell me???
