So what's the current Two stroke oil favorite for

[jellyroll]

Oh if it matters that saw is a husqvarna 55.

Walmart has quicksilver PWC oil in the quart for $9 it is JASO FD on the bottle.

It's funny how you call someone a liar when something doesn't fit your flawed and frankly moronic ideas.
Ethanols effects on breaking down lubrication are well documented. Lots of papers out there on the subject.
I supoose I will be called a liar for pointing out the energy density of Ethanol is less than gasoline as well?
That top piston doesn't look so great for such little time, neither does the middle one. The picture for the Chinese junk on the bottom is too poor to say.

I call you out as a liar because you are. You make statements of things you have zero experience on and present them as facts. It wasn't my Idea to put Ethanol in Gasoline.
Ethanols effects on breaking down lubrication are well documented. Lots of papers out there on the subject.
Then put it up! Lets see one. Because all I find is conjecture, and assumptions. Nothing close to a scientific study that examines lubrication in a pre-mixed system for a 2 cycle engine. My experience spans 4yrs using E30 in small gasoline engines, 2 and 4 stroke. In that 4yrs I have had 0 failures related to lubrication.

Nope, easily measured. But again it's a mute point as ethanol is an oxygenate and as such it increases burn efficiency. https://www.thaiscience.info/journals/Article/JOSE/10889623.pdf

As expected you completely missed the point of that post, Point being, that there is plenty of residual oil after operation. Which, according to many of the posters in this thread, is the metric for gauging suitable lubrication.
Again your "compromised Lubrication" statement is a lie.

And last but not least. If you think E30 boosts your performance you are nuts. Unless lower HP, compromised lubrication and and increased fuel use is a boost in performance to you.

And yet, here is another example of the compulsive liar you are.

If you have some evidence of living on my part let's see it.
It's not my job to do your research for you, but a quick Google search will provide you with multiple white papers on ethanols effects on lubrication.
You are the poster child for the Dunning–Kruger effect.
And you last paragraph is a perfect example of this. Ethanol in fact has a around a 30% lower BTU content than gasoline.
I know you think that video is impressive. It's not. Ponderosa Pine, of which I cut a bunch this year is super soft. My 361 blows through it ridiculously fast. And the stuff I am cutting is from a very arid climate with much closer growth rings.

My dad had a 625II he bought new, Canadian tire oil, jonsered oil, Walmart oil and anything else he bought on sale. The piston still looks brand new after what 30 years.
I run quicksilver marine 2 stroke semi synthetic, jonsered and stihl oil, 40:1 never had any issues.

stay away from the Tc-3 boat motor 2 cycle oil, its designed to not fully burn at temperatures below something like 450 degrees, its higher viscosity and can cause gummy build up in ports and screens and higher oil residue left behind in the crank case. I ran the quicksilver air cooled version stuff for years and it worked great but I noticed a big power pickup switching to vp, orange stihl and schaffers 9000 versus the quicksilver.

Not disputing energy content. And the point is still mute when mixed with gasoline.
From the study in a previous post.

From the study, the following conclusions can be deduced:-

1. Ethanol blends and oxygenated additives in gasoline cause improvements in engine performance and reduce exhaust emissions. 2. Ethanol-blended gasoline with oxygenated additives leads to a significant reduction in exhaust emissions. As all engine speeds, the values of CO, CO2 and NOx were reduced. On the other hand, HC and O2 emissions were significantly increased. 3. The addition of 69.5% of ethanol-blended gasoline with oxygenated additives was achieved in the experiments without any problems during engine operation. However, without additives the performance was better by to 40 % beyond what was absorbed resulting in abnormal combustion, vibration and starting problems.

From their doc you posted, could not find any literature stating quicksilver to be jaso rated, the following sentence is from the schaffers tech doc
Synthetic 2-Cycle Racing Oil meets and exceeds the NMMA TC-W3, JASO FC, JASO FD, ISO-L-EGC and ISO-L-EGD; API TC lubricity and pre-ignition performance.

I ran and still use the left over Qsilver to assemble saws (easy to see whats been lubed being silvery blue), never suffered a single saw failure or plug foul using it at 40-1 or even at 25-1 but it smokes like a tar kettle and made noticeably less power as well as clogged the flame arrestor screens every 15-25 tanks esp on the trimmers. I run schaffers in winter because its viscosity is lower making it pour easier/ settle faster during measuring meaning it should also flow better in a cold saw crankcase and as a bonus no screen soot buildup after 25+ tanks. The last thing noticed is the first 2-3 starting pulls are easier after the saw has been sitting a few days. Before I had to pull 2-3 times slowly before it would become easy enough to pull start without causing shoulder damage LOL.

You need a video to prove Pondo is soft?

Na, I wanna see a video of this! Lets see your 361 blow through 24" of (Yellow Pine)!

Oh....and by the way (Southern Yellow Long Leaf) is one of the hardest of the soft woods.

 

[jakethesnake]

Yellow pine is good building material. Used it quite a bit for that.

Poplar is great as well and it is used more often since pine is not commonly grown here.

 

[BerkshirePaws]

While ponderosa pine is considered a “yellow” pine I didn’t think it had much (anything) in common with southern yellow pine.

While ponderosa pine is considered a “yellow” pine I didn’t think it had much (anything) in common with southern yellow pine.

Over 10 species of yellow pine within North America . Majority are used within the wood manufacturing industry . They share common traits that make them suitable for structural to decorative purposes . Actually pine is the largest supply species for pressure treated products .

 

[Karrl]

That’s pretty soft

If my saw behaved that way, I'd be checking the tune. Does it 4 stroke out of the cut?

Well then! I stand corrected.
There is a difference between Southern Yellow Longleaf Pine and Ponderosa Pine!
Being from the Northwest it looks like Ponderosa to me.
