It is important to remember that the ratio of gasoline to oil differs depending on the manufacturers so you should check the owner's manual or contact the manufacturers directly if you're unsure. Most engines will require a 50:1 ratio of gasoline to oil; also some need a 100:1 while a 24:1 ratio is recommended during the break-in period.

You need to pre-mix the oil and gas by firstly deciding which ratio is appropriate so if it is 50:1 then you need 50 parts gasoline and one part oil. To calculate and measure these amounts you should convert six gallons into ounces because this will make the conversion to pints a lot simpler. 128 ounces is equal to one gallon so you should multiply six gallons by 128 ounces, which should result in 768 ounces. Using the 50:1 ration, for example, divide 768 by 50 to get 15.36 ounces of oil. For the 100:1 ratio, divide 768 by 100 to get 7.68 ounces and finally for the 24:1 ratio you should divide 768 by 24 which will result in 32 ounces of oil. Once you have done that you should mix the calculated amount of oil with six gallons of gasoline. Using the most common ratio which is 50:1, you should mix six gallons with 15.36 ounces of oil. When you have carried that out, the mixture will be complete.
