Hey Messenger
Try running 90wt. gear oil at 16 to1 Be sure to use high octane gas, though.

Stihl has maintained since the mid 80's that running more oil than in 50:1 will increase carbon and reduce life. They had no reason to say this other than for engine life. Heck, they'd sell more oil at 40:1.
Funny thing is.. most other major manfs say to use the same 50:1 ratio.

lol Stihl used to even more for "not outs". Today.. I figure it's a subtle way of saying, ours is better, and you use less so it costs less. :monkey:Unless you use a competitor's oil. ie., Dolmar says use all other oils at 40:1.
