Best 2 stroke oil

Thanks, but this is the SDS for Castrol 2T (JASO FB) Durable Protection / Trouble Free Ride in Europe, not Castrol 2-Cycle Synthetic - the bottle on the previous page.

So I have been using some Stihl ultra 2 stroke oil in my Stihl 2 strokes. They say the new stuff is some sort of biodegradable veggie oil. Not sure I want oil in my saws that is designed to go bad. What is a good alternative and is the veggie blend ultra any good?.
Echo Red Armor, VP, Amsoil Saber.... all get my vote over Stihl Ultra. To me, Ultra runs dirty and smells like racoon breath.
 
Anyone running or know who makes Stens Shield 2 stroke oil ? There's a full synthetic and semi synthetic both Jasco FD and ISO L-EGD. They sell for a decent price for a 16 oz 2 pack with a measuring bottle.
 
I prefer a two cycle oil with a fuel stabilizer. The one & done bottles are nice, but if you make several cans throughout the year the squeeze bottles are handy.
 
Can somebody find any product data sheet or SDS, or MSDS of this Castrol oil?
The only thing I was able to find is that the Castrol product code is 215302 or it replaces this product code.
I'm interested in looking at its physical properties.
Took a while, but here is the msds for the Castrol ope 2 cycle oil....

Even though it is made by the same folks who make the VP oil, Lubrication Technologies, it looks like it is not the same oil. The flash point is 92C. VP lists a flashpoint of 80C. It also has a higher viscosity (43.7 vs 36.2 at 40C) and a little higher density than VP. The composition is listed differently.

For comparison FP Husky XP+ is 96C, viscosity at 40C is 47.5 cSt. For Echo Red Armor the numbers are FP 73C, viscosity 64.3 cSt at 40C.

There was a write up several years ago where a guy tested 2-stroke oil in his Vespa from what I remember.
 
I dont know if there is a "best". Ive ran everything from boat oil tcw3, stihl, honda hp1, even some castor maxima for the smell. All of my stuff is tuned for 40:1 though. I still have a working srm3100 echo kioritz string trimmer i bought new in 1997 that runs like a champ. I think also there is a benefit to non ethanol fuel which i have always used. The last few years ive been running the vp 40:1 canned fuel from TSC, it also smells good and is shelf stable in the machine for over a year. My chainsaws love it.

It's a bit thin for me... I guess I'm showing my age, but when the equipment manufacturer recommends their oil and it is a certain viscosity I just don't feel comfortable going with a thinner oil. Of course I could run a richer ratio but my br800 protests when I do that. The market is wide open for someone to manufacture an oil that is certified JASO FD rated, 350 degrees flashpoint, ester fortified, fully synthetic, viscosity of around 60/15, has a nice 2 stroke smell, bright red or blue color, available in small bottles, and sold at Walmart and various other retailers. Instead, we mostly find semi-synthetic, thinner, not FD certified, low flashpoint oils that are nowhere close to being ester fortified. "Where's the beef?" The worst part is that Stihl makes this stinky and dirty oil that has it's own niche and is, for the most part, available only at Stihl dealers who are far apart and too often make me angry because they don't give a flip if their customer service is A+. I'd rather just go incognito into Walmart, buy my oil and a drink, and hit the road with a jolly bounce in my step.

The viscosity of the unmixed oil does not necessarily translate to the viscosity of the residual oil in the hot combustion chamber after a significant fraction has flashed off and burned. We don't know the viscosity in the engine. Of the four oils mentioned above, Echo has the highest unmixed oil viscosity, but also the lowest flash point. What does that mean regarding the residual oil viscosity at operating temperature? At operating temperature, the viscosity of the various residual oils is probably very similar.
