A 40:1 ratio would work out to 3-3.5 oz. of 2 cycle oil, to one gallon of fuel.
A 40:1 ratio would work out to 3-3.5 oz. of 2 cycle oil, to one gallon of fuel.
There is 128 oz in a liquid gallon so to achieve a 40 to 1 ratio you would add approximately 3.2 oz of 2 cycle oil to one gallon of gasoline.
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.
1 gallon = 128 fluid ounces 1/50 of a gallon = 2.56 fluid ounces
.5 gallon = 64 ounces64/40 = 1.6 ounces
It depends on the mixing ratio of gasoline / oil for the specific piece of equipment you will use the gas / oil mix. Most lawn equipment such as weed eaters and leaf blowers require a 32:1 mixture. Since 1 gallon of gasoline is 128 ounces, it is necessary to mix 128 ounces (or 1 US gallon) of gasoline to 4 ounces of 2 cycle oil to equal 32:1 ratio.
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
It requires that you mix 4 ounces of 2 cycle oil with one gallon of unleaded fuel to create a 32 to 1 ratio. Make sure you use 2 cycle oil and not regular oil. Also make sure you use the correct octane fuel. Lots of 2 cycle engines require at least 89 octane fuel. Check your owner's manual.
5.5 ounces to a US Gallon which is 128 ounces. 24 divided into 128 = 5.33
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.
