Service Ratios: Normal use ratios are 32:1 to 50:1. Racing requires greater oil content. Ratios no higher than 40:1 should be used. Small displacement, high-RPM racing engines should use ratios no higher than 32:1.
Mixing: Best blending results by pre-mixing total amount of oil required in 1-gallon of fuel, then mix with rest of fuel. Mix only the amount of fuel/oil needed for each day's use. Re-agitiate fuel container before filling gas tank. Keep fuel above 40 degrees F during and after blending.
Jetting: Increasing oil (per gallon of gas) may require increasing jet sizes. Decreasing oil (per gallon of gas) may require reducing jet sizes.
