I have been using whatever was cheap at the gas station, mixing 32:1 with regular old 87 octane with ethanol on it and tuning for that mix, for years. I can hear the palms slapping the foreheads, and I know a lot of people get good service out of various tools with 50:1 and have been for years. But a variety of trimmers and saws have performed well for me on the 32:1 so that’s what I do. (Including a Stihl FS72 trimmer with about a zillion hours on it, bought new in 1992, still on its original fuel lines and only now starting to show signs of needing a carb kit! I pulled the spark arrestor screen out several years ago for the first time and it was not plugged, the port looked okay and the piston did too.)

I run trimmers pretty hard, clearing big areas inaccessible to the tractor, so maybe the long periods at fairly high throttle openings keep the exhausts burned cleaner than people who are trimming around fences and flowers at lower engine speeds. But my experience leads me to believe that 32:1 puts plenty of oil into the engine without being too dirty and requiring undue decarbonization effort.

I bought some Stihl Ultra oil last week though to try it, and it does smell better than the gas station cheap oil. Kind of reminds me of being around two-stroke MX bikes running synthetic premix oil. Maybe I ought to try some Klotz or Maxima or Bel-Ray next.
 
Amsoil Sabre @50:1 in everything. Been using it for the past 10 years in Lawnboys, Husky trimmer, Homelite XL12, Homelite XL, Craftsman blower. Zero trouble. Neighbor has a lawn business. Amsoil Sabre is all he has used for over 10 years.
Same here but 40 to 1 .
 
I am not into chainsaws and power equipment, but this is a subject near &
dear to my heart :)

I run 20:1, and I prefer oils that are high quality synthetics and castor. People
have mentioned Yamalube 2R, 927, Maxima, Bel Ray and many more.

I run 20:1 in my watercraft race engines, because of documented dyno tests,
and manufacture testing (like Husqvarna MX), testing I completed while working
for a Watercraft manufacture, and racing experience.

Back in the 90's (in Calif. The Smog Law capitol ) The manufactures recognized
that when a watercraft started with a cloud of smoke, that was a bad look for
2-stroke engines (Yamaha was the worst). So many manufactured oils to smoke
less.

A common seizure on watercraft occurs on a short wot run and the engine suddenly
shuts off, and then restarts like nothing ever happened. The seizure is so benign,
that most customers keep riding their watercraft until the engine seized 10 to 20
more times and it finally doesn't restart.

The most common cause is an impeller with too much pitch. People think they can
just add a larger impeller and they will go faster. But the impeller loads down the
engine, holds the rpm ~1000 r's below peak hp and creates a lot of extra heat that
leads to detonation and finally preignition.

One of my riders made that mistake (while using 20:1 Maxima 927), and if he was
running 40 or 50:1 it should have seized on his first wot pass. If he had used a
tachometer he would have known the rpm was too low, and to take it back home.

But he didn't have a tach. He continued to test and made the situation worse. When
the engine finally seized, it locked up so hard that the impeller and driveline kept
turning. It twisted the drive shaft, and bent the drive shaft nearly 90' and shoved it
through the hull and it sank. :)

IMO, running 20:1 927 prevented the engine from seizing initially. But when it did
finally seize, it seized hard.

I agree completely
Heat burns oil period, no argument in that
In long hard cuts like milling, you'll need more oil to compensate for the extra heat thats burning oil faster than its going in
I mix my 100 over cc with 25:1, because they get pushed hard when they come out for the big hardwoods
Good post

How many & how long do you cut with your saw at any other than wide open throttle ? none I hope or you are not using your saw as it was intended to be used the minute fuel mix ratio's have com about through the quest to reduce emissions & from a manufacturers point of view if it passes the emissions test & lasts the warranty period using xx/1 oil/fuel ratio thet're not going to recommend using more oil to prolong the lifespan of the piece of kit why make a saw lasts longer "Bad for company profit /trade I'd say since specialist 2smoke oil was developed I've used nothing but a 32/1 ratio in the works money earning & my own saws & never had an oil related or plug fouling problemto me correct carb tuning has much more effect than a extra tiny amount of oil in the mix
Yea, I couldn’t understand why any position other than full open or there abouts
would be of any use, unless you wanted to tickle the wood.
 
I can honestly say after switching over entirely to Echo Power Blend...I don't end up smelling like 2 stroke exhaust as bad, and it does not smoke as much as the previous conventional oil I was using . Using it 40:1
