Ethanol and Fuel Quality

[royster]

Damn guys .....we should start a whole new thread on fuel quality.

Ethanol would be the likely culprit. It will eat some fuel hoses and even dissolve cheaper fuel filters (it attacks the glue holding the filter screen in place - yay, dissolved glue heading for your fuel delivery...)

Theres a few places around my way that sell marine grade/ethanol free fuel. Its over a dollar more a gallon than regular. The regular fuel is supposed to be 10% blended but Ive heard that it can be 15-20. A wiser man than I had recommended I get the ethanol free for my lawn equipment and carbureted vehicles to help save them from failing rubber parts in fuel. Hopefully the new fuel I just put in my truck with stabilizer will hold me over for now. Also need to run the truck more to keep the fuel from sitting.

Geezer101:
Far as I know here in Australia it is illegal to sell regular fuel without identifying if it has ethanol content (there's a price difference between regular and the blended E10 stuff) but no doubt it has been cut by the corporations to make money as there's no fuel excise levy on ethanol. I avoid running it in anything now as it has a bad reputation for causing all sorts of grief. You can add a fuel stabiliser to the tank if you know it's going to be getting on and off use.

Pennyman:
use sta-bil marine ethanol treatment in all of your vehicles - it negates the effects of ethanol in your tank. I run it in all my cars and it makes them run much better. My 92 Prelude mpg went up 3-5 mpg when I run it in the fuel.

Royster:
I am highly suspecting that ethanol is deteriorating the finger prime-pump on my chain saw (it’s dissolving) and the fuel cap gasket. I’ve heard horror stories about ethanol.
