2-Stroke Oil Mix FAQs
Most 2-stroke oils utilize a 50:1 mix ratio which equates to 2.6 ounces of oil per gallon. If using AMSOIL SABER, you can halve that value and use 1.3 ounces of oil per gallon instead.
For a 50:1 oil mix ratio, you'll need 2.6 fluid ounces of oil for 1 gallon of gasoline. This equates to 20 mL of oil for 1 liter of petrol. Use our 2-stroke oil mix calculator to calculate the precise amount of oil needed.
To know how much 2 stroke oil you need to add to a gallon of gasoline, you need to know the fuel to oil mix ratio. Most 2-stroke oils have a mix ratio of 40:1 or 50:1 (parts fuel to oil). Use our 2-stroke oil mix calculator to calculator how much oil you need.
