This means that for every 32 parts of gasoline, you should add 1 part of two-stroke oil.
For example, if you are mixing 1 gallon of gasoline, you would add 3.2 ounces of two-stroke oil.
It's important to use the correct fuel mix ratio because too much oil can cause the engine to run rich and lose power, while too little oil can cause the engine to run lean and overheat.
