I pre-mix 3 parts ASHLESS two-cycle and one part PS white bottle, keep anywhere from a quart to a gallon in the bed. Aprx 1 oz per gallon of fuel on fill-up. Two-cycle for lubricity and PS for anti-gel / cetane. Hard to measure the results; more "belt and suspenders" insurance than anything else. No smoke, that's for sure.
