I Have been using Amsoil 100 to one for years without a problem. I have used it in all my 2 strokes,down to the 20 to one chainsaw at 100 to one. never had a problem. i am a firefighter and we switched over to it for all our emergency tools. with 1 to 2 ounces of octane boost added per gallon . they all start on the first pull. It really works good and I seldom change plugs. I Have one gas can and put 6 oz into 5 gallons real easy. good luck Jack
