Yes, this has bin debated for awhile. My opinion and experience is that I run all my 2-stroke equipment on a 40:1 ratio with 93 octane and as little ethanol as I can find. Which around here is up to 15 percent.
I use a synthetic mix and have had NO troubles at all...
I've checked cyl, head temps with both types of mix oil, and found the synthetic blend runs cooler. And on a 2-stroke that will mean a longer life. plus I find them easier starting. not to mention it smells way better!
Now some will tell you run whats reccomended, Which is fine. But I'm sticking with 40:1 in everything...
On a side note, I had a guy the other day who said his Dolmar locked-up after the saw shop owner told him to start runnin Amsoil at their reccomended 100:1 mix!
This is the first personal account of this I've heard.. Not bashing Amsoil, but 100:1 seems awful lean..
