My shop carries byrons fuel, usually 10% and 15% "premium sport standard" which is 16% total oil synthetic/castor. I've been running the 15% in my 2-stroke engines and it works great. Should I stick with it or have them order me some 4-stroke specific fuel? I know the manual that I found on Horizon's site says 20% oil, or the next best 2-stroke fuel. But I would like some input from you guys who have actually ran these things.
Thanks again everybody
