    You need to determine how many ounces per gallon
    Simply divide
    12 ounces divided by
    16 gallons

    12/16 or 3/4 ounces per gallon
    (1 ounce equals 2 tablespoons)
    2 tablespoons equals = 6 teaspoons (12 half teaspoons)
    3/4 of 12= 9
    9 half teaspoons or 4 1/2 teaspoons per gallon

    What in the heck is purpose of adding octane boost to a low compression engine like your 2 stroke? It is a waste ..

    ANSWER: NONE. Low compression HT engines run better and get better fuel economy the lowest octane you can find.

    0 ounces per gallon sounds good to me too.
    themotorbikeguy, you only need to use octane booster with a very high compression engine, to prevent pre-detonation.
    These engines only have about a 6:1 compression ratio, so using octane booster will detract from your engine's performance.

    To answer your question.... there are 128 ounces in a gallon.

    16 gal = 128oz (in 1 gal) X 16 (amount to be treated) = 2,048 ounces
    1 ounce of boost or 1/12 (contents in bottle) (2,048/12) = 170.66 ounces
    170.66oz - 128 (oz in 1 gal) = 42.66 oz remaing
    42.66 - 32 (ounces in a quart) = 10.66 ounces remaining
    10.66 ounces / 8 (ounces in cup) = 1.33 cup
    .33 of a cup = 2.66 approx

    1/2 oz boost will treat
    1 gallon + 1 quart + 1-1/3 cups of gas combined

    128 (gal) + 32 (quart) + 8 (cup) + 2.66 ounces remaining = 170.66 ounces

    OR... 12 (ounces of boost in bottle) divided by 16 (gallons of gas) = .75 (3/4) ounce of boost per gallon of gas

    Choose which ever is easiest to mix..... That's math made simple.....
