I burned 1 gallon of oils last year milling. R50 showed no wear or build up. KL 200 was the same. K2 works great but the fumes are a bit rough. H1R I can't stand and on a couple saws I couldn't get it rich enough for my liking. 800 works good with no build up and will leave a wet piston even if up run out mid cut from a full tank.
One of the best experiences/answer I've read on this post.
 
That's quite the testimonial. Unless there are significant performance gains to be found with a less viscous oil like Motul 710 or Maxima Super M, I see no reason for you to consider anything else. The only other reason I could think of would be the cost factor for someone doing that much cutting all the time.
Klotz is cheap. $1 more than lucas so I can't see changing for a $4 /year in mix.

I ran out on a 390 and 395 mid cut and neither scored when running out of fuel. One was with R50 and the other with 800. I'm sure a run from idle at a full tank to empty was plenty heat soaked. I don't even cut the saw off to refuel. It was boiling the bar oil one day when it was 90-94° outside.
 
Just ran a tank of r50 mixed with 1 gal. 110sunoco/87efree@ 50/50 for 98.5 octane @ 32:1 through my 241c. Last several cuts were wide open and shut saw off right after last cut. Saw never ran better! Didnt notice much smell from the r50.
 
Do you even know what ash is?

per Jaso...

The JASO FD spec is 0.18% ash, less than 1/5 of 1% of ash content in the oil. Sulfated ash is the way to measure ash content by the way and its biggest contributing factor is metallic additive such as zinc and calcium.

Hows that?

The help keep the components blended too.
No one adds them for fillers ss solvents are expensive..

Well considering gasoline is the biggest solvent in the gas oil mix. I'd have to say that any 2t oil that needs a bunch of solvents to keep components blended...well just plain SUCKS

According to belray - yeah I know they are "biased". But the solvents are the cheapest raw material in 2t oil. Maybe maybe not, but it doesn't seem like a statement that is that far fetched at all.
