I noticed the mystic oil in those tests a few pages back. Middle of the road on those tests. But meets our ram requirements. Jaso fd passed. Any thoughts? I think it's available at TS or their knock off stores

Yeah.. They usually kill em long before the lube does...
Sans one crew here.. Those boys drank the 70:1 opti 2 koolaid..
1 year and out...
They runnin 365xt's...
Of all models, they could use a little more oil... /-:
I'm gonna try 4 oz per gal and retune. Maybe next weekend. Time some cuts and see what gives. Who knows.

4oz.? Cool
Your point?

Figured maybe the "old school" oil might be the reason behind the "more oil = more power theory". Curious is all
I have never read that, nor seen that and not from lack of trying.
I wish I had time to test some of this. The muffler on my 046 isn't oily inside with the 800. It's tuned to around 14k with fingers but no compression increase. I've been too lazy to pull it apart and cut it. It's been run on 32:1 motul for the last few gallons. Before that I finished up a quart of R50 with it and a 395 that was here.
And Andy, if your blowing unburnt oil out the muffler your leaching heat and hp out if the combustion chamber. Its likely you will have deposits sooner or latter in the exhaust port from the unburnt oil accumulating. Potentially the same issue with the ring grooves on the exhaust side of the piston.

Im just thinkin out loud but if the port , rings, and mufller r staying alil wet the wet oil isnt gonna turn into carbon is it? Wouldnt it be the burnt depoists that form buildup or the burnt depoists with the oil together?

I have at least 50 tanks of R50 through this @ 32:1 since the end of last summer. I aint the only one throwing up actual pictures that were taken from saws that get used, and I havent seen anything even close to what you are saying that we will see.

Just thinking. What if a test took two chainsaws brand new and mixed the two leading oils discussed here at 100:1, like Amsoil claims to be able to run at, and fill the saws.
Then zip tie the triggers to WOT and see which one fails first. For a longer run until failure mix at 80:1. What if they don't fail? The winner would certainly be the stronger oil, right?
Wouldn't have to use a Pro Saw either. A $200 homeowner saw would suffice would it not? I'd be curious to see what would happen. And I wonder what the inside of the engine would look like.

Something like this is the only way you could really test the limits of an oil. Most of us aren't willing to go that far in order to answer these questions. Factories can and do. That's what I mean when I say that most of us don't have the means to find real answers.
Might as well leave the cylinder cover off in order to speed up the process.
Personally, I would warm the saw up first, then start the test.

I wonder if the Oil Manufacturers have done this? Maybe we should ask? I'm sure the Product Manufacturers won't tell us their results. They'd claim "that's too much information" for us to know.
Racing extremes is where R&D is constantly focused, looking for failures in order to improve products. Instead of starting at the 32:1 safe end I just thought a test at the other, or extreme end would close down the conclusions much faster. The amount of $ that is being spent on oils (me included) is way more than a combined effort in buying new saws for some scientific test or whatever us backyard non-engineer types could do. Certainly not saying there aren't any engineers on this site but most of us are not. No offense intended by any means guys.

You buy the saws, I'll burn them up 
If there was an AM cylinder that could be counted on to be very consistent and good every time, you could use the same saw and just swap topends. Yes, this test might damage the bottom ends, but I doubt they'd fail before the topend burnt up.

I'd expect to see the crank die first.
