The maximum amount of oil that meets this standard is 40:1, or 3.2 ounces of oil per gallon of gasoline. 50:1, or 50 parts gasoline to 1 part 2-cycle oil is 2.6 ounces of oil per gallon of gasoline. Superior oil is synthetic, or blended synthetic oil. There is very little difference in 50:1 and 40:1 fuel mix.
