## How do you calculate ratio mix?

To create a ratio in the form of 100:b, divide the volume parts of Part B by the volume parts of Part A and multiply the result by 100. This yields a volumetric mix ratio of 100 : 11.8 The ratio can also be normalized to the form a:1 by dividing the volume parts of Part A by the volume parts of Part B.

## How do you make 50/1 fuel mix?

You want to mix 2.6 ounces of oil to one gallon of gasoline for a 50:1 mixture. If you’re mixing up two gallons of gasoline you will have to mix 5.2 ounces of oil to two gallons of gasoline for a 50:1 mixture. I would recommend using fresh gasoline that has an octane rating of 89.
