- If your interested there has been lots of testing,so your not the guinee pig at all,check out Sarge @LS1.com using synthetic 2 stroke oil in gasoline 1 oz per 5 gal,,,,,lubricates things like fuel pump,injectors,disapates water too ,we have crap for gasoline and I think its worse than ever,not to mention poor shelf life.Sarge and his guys did the leg work and we reap the benefits ,so to speak,quiter running engine and slight increase in mileage too,I can do this all day,I use in my ,2007 M109r,2008 Gt,beer wagon ,snowblower,,without any ill affects.

very interesting and thanks
