2.5 gallons of gas how much oil for a50to1
To achieve a 50:1 oil to gas mix with 6 gallons of gas, you need to calculate the amount of oil required. For every 50 parts of gas, there is 1 part of oil, so for 6 gallons of gas, you would divide 6 by 50. This equals 0.12 gallons of oil, or approximately 1.5 cups. Thus, you would mix 6 gallons of gas with about 0.12 gallons (or 1.5 cups) of oil.
1 gallon of oil to 250 gallons of gas is 1.953125 ounces per gallon; you would need 39.0625 ounces of oil for 20 gallons of gas.
55 gallons X 2.6 oz = 143 oz.
17.6 ounces of oil for 2.75 gallons of gas to get a 20:1 mix ratio
