Re: what brand of 2 stroke oil?
The engine makers oils are generally the highest quality, they are made this way to reduce warranty claims. The TCW3 rating allows for things like piston scuffing, etc. All oils are not equal, the more expensive generally have more carbon reducing additives. This is more important in todays higher performace, close tolerance engines than the engines of 15 yrs ago. Use of cheap oils may not show effects until a couple hundred hrs of use. Many mechanics swear that many powerheads fail due to cheap oils producing mucho carbon buildup.<br /><br /> I believe that the Mercury Premium Plus is the best, I find more people with high performance engines run merc oil. Quite a few enthusiasts use Amsoil(synthetic) also.
