    Yea, I’m in Communist California. It’s actually cheaper for me to fly my plane somewhere than drive.

    The cost today for 90 octain Mogas is $3.00, 100ll is $4.10. It’s generally at least $1.00 cheaper for The ethanol free fuel.

    It definatly saves me a few dollars over time. I generally burn 11-12 gph.

    I see mentioned:
    1. Clean burning
    2. "cleansing effect on the fuel system"
    The two items aren't dependent on one another. "Clean burning" happens in the cylinder. Item #2 is describing a solvating effect- the material is partially dissolved which then clogs the injectors. The gum is likely oxidation products of alkenes in the gas. They form in a manner similar to oil-based paint drying. Adding a fuel stabilizer reduces these gums, although there is evidence that ethanol makes it easier to form the gums (this is the an easily available reference: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.735.9392&rep=rep1&type=pdf )

    Using the fuel (drive or fly often) so there is always fresh fuel in the tanks, using a fuel stabilizer, or draining the tanks will prevent problems.

    Ethanol gasoline has been around since the 1970s in my area. Other than a few rubber parts in some of the old cars and motorcycles (which are long gone by now) failing, I haven't seen any of these problems. Any vehicle built in at least the last 25 years should be more than capable of running fine on fuel with ethanol in it.

    I stop at CTJ frequently on my trips north. It’s around a 3 hour flight and makes a good place to stop for a few minutes. I’m heading to Chicago next week and plan on eating lunch and filling up there.

    Station about a half mile from me on the way to the airport has Zero ethanol gas at $2.99/gal. Regular E10 is $2.84 at the same station. 100LL is $4.77 at the airport. I use E0 in the 2 Stroke engine on my Ultralight. Since the overhaul is so cheap and 100LL will reduce the TBO so drastically, it’s kind of nice to have such an easy source to save money all the way around.

    Cheers

    Who believes you can save $22,000 on 1800 hours of flying?

    1800 hours * 10 gal/hour = 18,000 gallons
    Let the price difference be $1.50 / gallon
    18,000 gallons * $1.50/gallon = $27,000
