What would a 20 to 1 ratio be for gas to oil mix?

A 20 to 1 ratio for a gas to oil mix means that for every 20 parts of gasoline, there is 1 part of oil. To create this mixture, you would divide the total volume of gasoline by 20 to determine the corresponding volume of oil needed. For example, if you have 20 liters of gasoline, you would add 1 liter of oil to achieve the desired ratio. This type of mix is often used for two-stroke engines to ensure proper lubrication.
