very thirsty huh i know a guy who gutted the stratos on a 211 and made it a good saw.
Its alil finicky off a long idle and has a bobble and catches right up and wont bobble again unless idles a minute or so which I dont idle that much very often anyway. When pouring the fuel to it it is a cuttin son of a gun with PS chain. Im cutting with r2 at 20to1 and im not so sure that its ever run better

Keith this is what you need in that 241. Loggers swear by it at 25-32:1 and get almost 4 years out of their 372's. Running it at 50:1 they were getting 6-18 months. Same refinery makes the base oil for the Stihl orange bottle as this oil. Probably blends here in Shreveport at the same plant also. Loggers tell me they never inspect the inside of their saws for buildup....stupid if it's still working. Once it breaks...buy a new one or I get it. Then it goes to Keith for rehabilitation or resurrection.

Well, Wendell, luck to you, but I follow a philosophy, more in line w/ "Follow Mfr recommendations", because I (had) a new $750 saw that ran 2-days before it locked a piston ring down tight, and they wanted $700 (OEM piston/ cylinder) to repair out of warranty, 3-yrs later. I (thought) it had run out of gas (was at end of cut anyway, by coincidence), then had back problems, so never tried to fire back up until 2+ yrs later outside warranty period. I had run 40:1 crapsman, (tho book said 50:1). I FIXED it w/ a $12 piston ring and ignored a very small scratch. There was a film of carbon so small/ light, you (would have) thought made by Magic Marker, but it had ring locked down solid. I have a good number of hours over past years and suspect compression has come up as ring has seated, but I NOW use ONLY (Synthetic) at 50:1. There was also the guy running the TCW oil, where your book says "Never use TCW in air-cooled..", so best of luck (again) on your "Marine Stabil"; NOT for me

Over there
50:1 makes me nervous but im sure it perfectly fine.

Keith i've found that my A/T saws run better on HP2 at 40:1 vs. 32:1. 32:1 seemed to slow them down and the throttle response wasn't what I like it to be. The other saws were ok at 32:1 but still seemed to run better at 40:1. Idk 32:1 just seem like too much with that oil.

NOTE that does NOT say "synthetic"? WHY NOT take advantage of the newest technology of the synthetics?

So go buy a can of 40:1 Trufuel and a can of 50:1, and try 1-3 cuts w/ each (I.e. Experiment); what you don't like, use for Storage fuel, or mix together and get 45:1, LOL
You KNOW that uses the CLEAN, hi-octane and synthetic

What is with you slackers. Hardly enough discussion here is the last 24 hours for a coffee break never mind lunch hour. Had so much time left over I went to AS to scan the trading post...

Keith knows I was joking. I only use 800 off-road in all my saws, ported and stock, with zero issues. The Logger that uses Safe Guard oil says he's found out that it's the QUANTITY of oil not the TYPE of oil that counts. He's also used Lucas synthetic and husky synthetic oil but didn't notice any improvement in the life (longevity) of his saws. I doubt if anyone reading this thread has ever experienced an engine failure using a 32:1 mix with ANY brand of oil. If so, I'd like to hear about it.

I almost seized a 066 once on belray. It made about 3 cuts and started slowing down. Needed a bigger jet in the carb. It was all I could do to keep it under 14k rpms on that mix. It didn't totally stick in the cylinder but put a few marks in it. That was on 32:1. If there wasn't that much oil it probably would have locked up tight.

"never inspect inside of their saw.." or BOSSES SAWS? Ownership makes a difference in how the equipment is treated.. LOL :) ACTUALLY, I would say "Sad But True"
Not necessarily, these guys KNOW what works and what does not from many thousands of hours trial & error, as simple as fellows believe they might be. Modern mineral oils made from quality base stocks are fantastic, assist in the combustion process rather than resist it. Those guys could replace a saw brand new each year easily with the savings from not running synthetics. Running oil that's 3x the price that offers less protection, tuning issues, promotes blow-by from lack of ring seal, is hygroscopic (attracts moisture inside crank case) and resists being combusted......well to some ain't such a good idea. You will get more power, better ring seal and less varnish not running synthetics. Don't forget how oil is used in 2t applications is totally different to 4t. A two stroke burns oil, what do you think burns better providing more power? Mineral derived or synthetic ester? It is a chemical nightmare making synthetics work well in 2t, a lot of problems to overcome. If you want the BEST lubricating properties, run Caster nothing will beat it at that one quality.

(Anytime) you run a saw, I.e. Continue to run, knowing in your head (e.g. ear) that it is running lean, you are dancing with the devil....
