    Hi guys,

    What is the recommended fuel oil ratio.

    I started out using 8-1. 8 ounces oil to 1 gallon fuel.

    I was told I could do 5 or 6 to 1.

    I am currently using 5 -1

    8 ounces to one gallon is 16:1 because there are 128 ounces in a gallon. 4 ounces to a gallon would be 32:1 ect.

    Mini Rok manual says 30cc of oil every 1.000 cc. of fuel; however, I am new to karting and I know there’s more to it. Anyone want to share there experiences?

    Look back at Walt’s post. 4 ounces of oil per 128 ounces is a ratio of 32:1. 30cc of oil per 1000cc of fuel is 33.3:1. You say that you’re new to karting. Go with the manual recommendation or maybe just a little more. Work on chassis setups and consistent lap times. Have fun.
