I agree some oil is clearly better than others but most oils today will ensure long service life. In many years I have yet to see a failure directly related to oil, have you? My point being find a good oil at a sensible cost that aids combustion and focus your efforts elsewhere improving performance. Saws a low output commercial two strokes that are far from high BMEP performance 2T's. They simply don't need performance oil, quite the opposite. I could easily replace a pro saw each year by not buying performance oil and have better performing saws. I get guys like talking oil and are passionate about their choice but rarely are there choices based on rationality and often they are not doing themselves or saws any favours. I say choose a cost effective oil that works and focus your thoughts in other areas. I'm a sucker too, I drop in here and read the oil thread for what reason I myself are not sure. FWIW I'd be more concerned about a the base stock of an oil than its additive package, certified rating or claim to be synthetic. Synthetics were originally designed/made for extreme temperature aircraft turbines as they evolved making extreme heat. A saw will NEVER see this heat environment, and most synthetics are not that synthetic. Price is what tells you how synthetic an oil is as is costs a chit load to make. It does'nt combust well, produces varnish/glazing eventually leading to blowby has poor ring seal, irritates ya eyes, stinks & real stuff costs plenty. I am not sure what there is to like about it really.
After you find a good oil you would be better off testing the fuel quality that you mix it with. Probably for less than $50 bucks with a tin can some chilling ice, a pressure gauge (0-10psi) some tube and JB weld you could make your own RVP tester and test the volatility of you gasoline so you get clean burning max power producing mix in ya saw.Ya know that tshhhhh you get when you shake ya mix can and open the lid giving a great smell.....well that's the pressure of your fuel escaping. Those 'front ends' are what you don't want to escape and keep in your gas. Better off testing that so you know what gas source is the freshest best quality for your saw. About 5psi is great 1 or 2 not so good. What I'm getting at is their are other things that your probably better off focusing on.
