How much oil do you mix with 2 5 gallons of gas in a 501 ratio?

To mix oil with gasoline at a 50:1 ratio, you need to calculate the amount of oil for every 50 parts of gas. For 2.5 gallons of gas, which is equivalent to 320 ounces (since there are 128 ounces in a gallon), you would divide 320 by 50, giving you 6.4 ounces of oil. Therefore, you should mix 6.4 ounces of oil with 2.5 gallons of gas.
