Seems the most common recommendation is to use the same fuel you plan to run later. Why is that necessary? Got a new Saito 62 c/l, seems they need about 2 gallons to get happy. I plan to us Powermaster YS 20/20 later. Why can't I use a cheaper 5% fuel with the same lubrication as the more expensive 20%?
Randy Smith, would appreciate your thoughts on this..
