What oil is best? and what ratio?

[EFSM]

40:1 mostly. Initially tried it at 32:1 and 50:1. Ended up splitting the differance.
RA is good oil but its not magic. K2 is a little cleaner and leaves just as much residual from what I can tell.

How good is the stabilizer in K2?

I liook at it like….if you use your equipment regularly you shouldn’t need a fuel stabilizer. If you don’t use it often enough that you require a fuel stabilizer, it doesn’t matter what kind of two-stroke oil you use as you’re not going to wear it out. I don’t know, just my thinking.

I choose to use better oils because 95% of the mixed gas I use is burned in customer saws.

It doesn't have a stabilizer and frankly I don't want one.
