I am going to try SEF (small engine fuel) next season in my gassers, it is no ethanol 93 octane and comes in either 40 to 1 or 50 to 1. Probably will get in quart bottles, could I add more oil to a guart of 50 to 1 to get to 20 to 1, and if so how much?
You would need to add 1.1 oz of oil to the container of 50:1 to get 20:1 oil mix.
