MAJOR Problems - Need Help Desperately

[BlueHUMMERH2]

10% is the upward limit of Ethanol in the US I think as normal fuel. Maaaaybe 15%. But I'm assuming the engine would run ok for a while on a blend like that. It really would only (maybe) at some point start to eat up the fuel lines and things like that. But not this soon.

Best of luck Brazi. As others have said, Fstop is the guy to go to for H3 related questions. I hope you can find a dealer nearby. This site might help:
