    I found a great website with an Ethanol Calculator to help determine mixing different blends of fuel.

    It can be very helpful when mixing E85 and Gasoline to find out what the percentage of Ethanol you have.

    I also found this... looks like something nice to have but it is a bit too expensive for my taste.

    I already purchased Summit's ethanol tester (the same one you posted about) and I'm going to fill up a half-a-tank, put some is a plastic cup (just a squirt) and fill up the rest of the tank. This will give me a median sample of gas into my car. I plan to keep a water bottle in the car for testing. I'll pour in the water, gas, and test. This way I can test the gas right at the pump and know what I have in as soon as I drive away.

    I have see that. Thanks for sharing.

    Remember when testing to fill to the meniscus with both water and E85 at each mark.

    As seen here in "A".

    It will raise the octane and keep your engine much cleaner with a lot less carbon build up.

    Nice find.
    In my friends truck gas is still cheaper in the long run over E85.

    I only get 91 in my town but we have a e85 station as well. Can you mix the two together to get a higher octane on the stock fuel system to get say 93? I used the calculator and it came out to e25

    im wondering the same, i used to calculator 10 gallons 91(e10) and 2 gallons of e85= 93.3, but would the stock fuel system be able to handle it? my FPDC is around 80 %

    more octane is better than less. you just don't want to lean it out too much. owners manual should let you know.

    I just discovered this strategy and tried it for the first time today in my Boss. The link to the calculator in the original post provides the answer. Basically if you first pump in 2.2 gal of e85 and then top off with 91 e10 you end up with e20 and 93 octane in the Mustang's 16 gallon tank. The state of Minnesota mandated several years ago that all gas be either e20 or e85. I spent several hours reading the research, done at Mankato State University, that led to the approval of the e20 ruling. They tested 80 non-flexfuel vehicles over a period of twelve months, comparing e0 and e20 and found no significant issues with driveability, fuel mileage, or component wear. The e85 I bought today cost $2.55/gal. so I saved about a buck filling the tank to gain two octane points. I'm hoping my TracKey will be happy and maybe give me a degree or two of timing advance.
