Remember Chain Saws are not high performance engines. For 50 years have used a 34:1 and have not noticed any unusual wear. Thanks
No disrespect intended but why do you run 34:1 when most companies recommend 50:1 or 40:1. From what I know in a high performance 2 stroke engine you would have a richer premix like you run. I run what the manufacturer recommends and really try to dial in the jetting. The way I figure it their must be a reason why the manufacturer recommends that premix ratio. :reading:

Well sure, there's a reason, or maybe several reasons, but what are they?

Better performance?
Longer lifespan?
Shorter lifespan?
Lower emissions?

The OEMs used to recommend higher ratios of oil, and there's testing numbers that indicate a 2-stroke will make more power the more oil you add, up to about 16:1. Adding a little more to a gallon of fuel doesn't really change your tune much, you're only changing the amount of fuel in the mix very little, but you can add some extra lube to the bottom end, which isn't a bad thing :).

Though you risk fouling plugs with a richer premix without adjusting your carburetor jetting right?
I've read about the 16:1 ratio being the max for power gain but I thought I read that was mostly for dirtbike hill climbers that are pretty much pinned and not ran at mid or idle. I could be wrong can't remember when I came across that.

Totally. Tuning needs to happen when it needs to happen, change in the seasons, change in the gas, change in the oil, bigger hole in the muffler etc.

I think you're right on the source of the HP info. I'm not suggesting anyone run 16:1, just pointing out that 50:1 may not be the recommendation due to that ratio making the most power, or making for the longest running engine. If a feller is happy at 50:1, that's great. If a guy gets a warm fuzzy feeling from an extra glug per gallon, that's cool too. Any problems with the tune are easily overcome.
 
Stihl Synthetic 50:1 in everything i own 2 cycle engines

One, and very important is the oil build up in the engine and muffler. That's why many saws don't start because the muffler don't have emission.

The more WOT in regard to bikes was always a put more oil in the mix to keep the engine in it's best condition/power output. Why would you run a saw with an incorrectly adjusted carb ? & how do you run your saw? on a stone age carb that most saws use there are only 2 positions idle /WOT, & not much wood cutting gets done on the idle throttle setting. The mix Ratio we use in our money (hopefully )making logging enterprise is dependent on the tree size being cut at the time,& varies between 32 & 40/1 the more oil being used on larger trees as the throttle is kept at WOT for a longer period of time In the early 40 years of servicing the saws we've never suffered a saw faiure that is /was oil related & as far as I remember had no plug fouling & we always get a better trade in deal from the place we trade them in as they have in the past stripped & found less wear etc on them at very similar hours run than saws using less oil in he mix.I am in no way trying to tell anyone the mix ratio they should run, only what the finding of ourselves has been over the years & yes we have run a number of saws at the recommended oil ratios & on stripping at around 1500/2000hr mark they had more wear on the moving bits than the more oil in the mix ones
