What is the ratio 50 to 1 gas mix for 5 gallons for gas?

To create a 50:1 gas mix for 5 gallons of gasoline, you would need to use 5 gallons of gas and mix in the appropriate amount of oil. Since 50:1 means 50 parts gas to 1 part oil, you divide 5 gallons (which is 640 ounces) by 50, giving you 12.8 ounces of oil. Therefore, for a 50:1 mixture, you would mix 5 gallons of gasoline with 12.8 ounces of oil.
