1 US gallon = 128 fluid ounces.
in a 100 to 1 ratio you would need to add 1.28 fluid ounces.
6.4 ounces for each gallon of gas.
1 gallon = 128 fluid ounces 1/50 of a gallon = 2.56 fluid ounces
.5 gallon = 64 ounces64/40 = 1.6 ounces
5.5 ounces to a US Gallon which is 128 ounces. 24 divided into 128 = 5.33
If it is a 50 to 1 mixture it would be 2.6 ounces per gallon
There are 128 ounces in a gallon. If you want 50 to 1 ration, you need to figure out how many ounces are in each part. Divide 128 by 50 and you get 2.56. Therefore there are a quantity of 50 2.56 ounces in each gallon. If you only need one quantity for the oil, then you need 2.56 ounces of oil. A 50:1 ratio is also represented as 2% since 1 is 2% of 50 (or 1/50 or 2/100). Easy as pi....
6 ounces
3 oz. per 1 gallon for a 50:1 ratio
1 Gallon = 128 ounces, so 1/20 of 129 = 6.4 ounces (call it 6 1/2 ounces).
There is a very simple solution to find your ratios. There are 128 ounces in a gallon and since we are always using a ratio of 1 for the gas all you need to do is divide 128 by the gas side of the ratio. The standard ratio seems to be 40 to 1 (40 : 1) gas to oil in which case we divide 128 by 40 and get 3.2. This means you need 3.2 ounces of oil for every gallon of gas. (128 / 40 = 3.2) I am confused as to whether you are asking for a 125 to 1 ratio or are confused and mean a 1 to 25 ratio. Here are a few values for gas mixing. 125 : 1 ratio is 1.024 ounces per gallon of gas 25 : 1 ratio is 5.12 ounces per gallon of gas 50 : 1 ratio is 2.56 ounces per gallon of gas 40 : 1 ratio is 3.20 ounces per gallon of gas
Since there are 128 ounces in a gallon, to get a 25:1 mix using 1 gallon of gas means you need 128/25 = 5.12 ounces of oil.
Most 2-stroke engines will run efficiently on 1/2 ounce of oil to a gallon of gas. Make sure it is 2 stroke oil, not regular engine oil.
