ok i need some help with math ok so i have NOS octante boost
and the whole bottle treats 16 gallons and its 12 oz how many ounces per gallon is my question

2. ### a/c manMember

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.

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.....
