AMSOIL SABER 2 Stroke oil allows you to mix one “two-stroke mix” ratio for all your two-stroke equipment. This means you mix one can of fuel for all your 2 stroke equipment. This means for all equipment requiring 50:1, 80:1, or even 100:1. Test conducted in the video showed that equipment using AMSOIL SABER 2 stroke oil was 96% carbon-free based on spark arrestor testing… Many Lawn Service/Landscape specialists mix 1 quart of Saber 2 stroke to 5 gallons of gas for an 80:1 mixture and use it for all their two stroke equipment.
