I had been having a issue with my boat not running right and by chance I was at a marine store talking to a guy that suposedly knows about fuel and the problems that are now plaguing the marine industry.
He was saying that the ethanol in the gas is nothing but a "filler" while it does burn it does nothing but give the gas companies a little more profit. While an indy car runs on the stuff it takes 4 time more aclohol to produce the similar bang for gas but the added feature is it is clean burning.
Now here is the problem, in a car the fuel system is a closed system which means the tank does not vent to the air. In a boat it vents to the air and it is always in a wet enviroment, Duh! so the ethanol is attracting and absorbing moisture. The moisture in the fuel now starts to corrode parts and break down the gas to the point where you start to have hard starts, rough idle, hesitation. ....sounds familiar??? I have at least 3 friends whos bikes were running poorly at the beginning of the season. So early this year there were some bike not running well threads, when at the end of the season they ran perfectly, this could be from the gas. If the gas had been sitting in the tank it could have done just what my boat did. I drained some fuel in the beginning and it came out like watered milk, which confirmed I had alot of water in my fuel.
I think he was a rep for the product Sta-Bil, anyways I bought some for marine use and went to the web site. It does show some photos of treated and untreated fuel and the rust that forms on parts.
He did make a bit of sence, and I learned a bit. If this helps out someone then thats is all.
From this day on I will not be putting any ethanol fuel in my boat or bikes and if i do i will use this stuff.
