    100% Gas vs. E10 (normal gas)

    Recently 100% gas has become available in my area. I know 2 strokes absolutely prefer the 100% gas (or non-ethanol) but not sure if the 4 strokes really need it like 2 strokes.

    So would you all pay a bit more for 100% gas than the crappy ethanol blend for the Ultra 250X?

    What octane grades is the non-ethanol gasoline?

    Is higher octane available with ethanol in your area?

    Believe or not we have it all--87, 91, and 93 100% gas.
    The 91 100% is the closest to me.

    E10 is 87, 89, and 93.

    Reality is your not going to notice the difference between 10% ethanol and no-ethanol on the 91 or 93 octane with most engines built in the last 10 years or so from a performance stand point.

    If the price difference is only a few pennies a gallon for non-ethanol go for it every time. Otherwise if we are talking like 20 cents a gallon difference and your driving an extra few miles to get it, I won't go out of my way.

    E10 gas is just fine,the guys who put threads up here that they damage their engines from ethanol gas is nonsense,there's some other reason on their ski or car that caused their probs..
    Damaged rubber fuel lines,fuel tanks ,fuel pumps is ridiculous ,if this was the 1980s 1990s maybe but today's internal parts can handle it.

    Ive owned cars 40 + yrs had cars go 200-300k miles no prob that can be related to ethanol gas ,Skis going 140-150 hrs as I usually sell them about then no issues What so ever and ride with guys 200 + hrs on skis nothing can be related to Ethanol..

    You can Google pics of "so called " damage from ethanol gas and I'll Google you 200 hr PWC gas tanks you can eat out of other than normal residue on the bottom.



    Sorry not buying this Boogeyman theory on Ethanol gas

    To explain yet again I was running 98 no ethanol for 6months. The gas station overnight changed to 100 with ethanol they didnt advertise the ethanol content and played it off as no different to the 98 just better in there words. I filled up put the ski in the water and kaboom. I rebuilt it removed the motec refilled the ski at another outlet with same 100 ran it in then kaboom. This is when I asked more questions and discovered the ethanol. I rebuilt again changed fuel supplier to 98 no ethanol and have done well over 100hrs without an issue. The gas station paid all rebuild costs

    Why do all the fuel suppliers have posted at the pump that ethanol blend fuel is not suitable for use in boats and watercraft if it isn't a problem?
