favorite 2 stroke oil

Opti-2 for premix: 2 year stabilizer, low smoke, carbon free heads and mufflers/pipes, and it has improve compression and power despite the "impossible/didn't happen/your imagination" comments I've read here in BITOG.
Amsoil Sabre Outboard for TCW-3: low smoke, corrosion prevention,carbon free heads and mufflers.

Of course this are recommendation for a normal power engine, if it is for a ultra high performance/modified/racing engine like a 20K+ rpm's racing go-kart, you should know what to use.

Best quality 2-cycle oil I know of is Amsoil, which I use in my power equipment.

For use as an Upper Cylinder (Fuel Pump) Lubricant, any TCW-3 will do; I use Walmart's inexpensive SuperTech brand at $12 - $13 per gallon.
 
Hands down best for storage and performance fuel/oil premix VP racing SEF.

Off the shelf oil hard to beat Mysic Sea and Snow.
 
Excellent advice. My account sells new snowmobiles with that oil as an option. And new Victory bikes during summer.
 
Mobil 1 MX2t was the "hands down" overall winner in years past. It's so good, people are still talking about it.

A second choice would be Castrol TT-S. It's also quite a good product, with excellent performance. You might not like the exhaust smell.

However, any JASO FC, and/or FD will work just fine or a possible alternate EG-D rating. Oils with those qualifications are very high quality oils and will likely meet any demanding use without any trouble at all.

What ever you do, stay AWAY from Redline Racing Oil. It protects engines very well under severe conditions, such as Kart Racing, but it actively promotes corrosion. The brass jets in carbs corrode nearly instantly, the crankshaft bearings about a week later. This leads to all sorts of problems. I lost a number of engines on the stuff and I'm not alone. All of them failed due to corrosion related issues.

Another quick note: 32 to 1 provides all the protection an average user/racer will need. 50/1 is adequate for light duty use, but you may see very slightly increased wear rates at high loads. 100/1 significantly increases wear rates, regardless of the oil chosen, period. 16/1 (when jetted correctly) provides the most HP. Don't believe the statement that less oil provides more power, it does not.

I thought it was 18:1...but I have been out of the game a while.

Keep in mind...that requires an app capable of running full throttle the entire time. If not running hard constantly...and I mean constantly... it is technically too much oil. The ultimate goal being to tune for maximum protection and power for your app without introducing excess oil into the system.

That's what I run in my 2-stroke OPE. 64:1 in them, both made post 2010.

+1.
 
Stihl HP Ultra. Fuel stabilizers mixed in, corrosion inhibitors included and great protection at 50/1.

The one interesting thing I found by looking at the MSDS of different oils was their flash point:

HP Ultra 220C (428 F)
http://www.stihllibrary.com/pdf/msds/Stihl_HP_Ultra.pdf

Amsoil Saber Professional 114 C (237 F)
http://www.amsoil.com/storefront/atp.aspx

Mobil 1 Racing 2T 110 C (230 F)

Echo Power Blend Two-Cycle 68 C (154 F)
http://www.echo-usa.com/pdf/documentation/50to1Oil_062707.pdf

Since the HP Ultra has the highest flash point temperature, it seems to me it has great temperature resistance.

Bonus! 176cc of two stroke goodness !

A very revealing test. I am not surprised at the performance of Pennzoil air cooled oil at 20 to 1. Nor am I surprised at the performance of the other oils and what happens with them.

MX2t performed wonderfully at low load conditions. Exactly where most engines operate. But not this test.

Often, but not always, more oil results in less carbon. When we ran outboard racing engines at 16 to 1, near zero carbon was the result. Especially on the cylinder heads, which remained 100% clean.

At 100 to 1, less power and more wear was always apparent, regardless of oil type.

Things to keep in mind. Motorcycle, scooter, chainsaw and other engines have very different loads. Big bore dirt bike 2 strokes are seldom operated at full throttle for long periods of time. Same goes for big bore, 2 stroke snomobiles. But, 2 stroke (real) aircraft engines operate at full power for many hours at a time. Pennzoil has done exceedingly well under such conditions, with a detergent that works under high temperatures.

However, when used on some large dirt bikes (often lightly loaded) , Pennzoil is not an ideal oil. With carbon buildup, ring sticking, power valve sticking and other problems showing up.

The last update was 2005, it is hard to even find Penzoil Aircooled anymore, it has been superseded by Penzoil Allsport I believe. I have been pretty active in the model community and Redline and Stihl HP Ultra are two of the favs,,, along with Amsoil. One adamant Amsoil supporter routinely pulls the cylinders and cleans the ring lands of carbon deposits.
I am a fan of the Stihl because of the fuel stabilizers and corrosion inhibitors. I can leave mixed fuel for quiet a long time it it still performs perfectly.
 
100:1 will not "always" wear more, that is like saying thinner oil is "always" better, it will depend on the oil and it's intended use, if you are using using a 50:1 oil at 100:1 sure it will but if you use Amsoil Sabre or Opti-2 at 16:1 even after re-jetting it will be a disaster. Check www.bridgestonemotorcycle.com/documents/oilpremix6.pdf‎, he concludes at the end of the article that additized oils should be used at their designed ratios and in the world of 2 cycle Gordon Jennings still is top notch
 
In my Kawasaki KTFR27A trimmer and Toro 210R I'ved tried:
1. Echo Powerblend
2. Royal Purple 2C.

I've now bought a six pack of Kawasaki K-tech 2cycle oil off Amazon. Its certified, JASO-FD rated, blend.

Royal Purple ran fine, but I'm worried about the lack of certification. If I went back to Full Synthetic, I would probably run Klotz Snowmobile Techniplate...its TCW3 and JASO-FD certified.

Note: Most oils, including Amsoil 2cycle are not JASO rated. Its probably fine, but I hate that they say "Use wherever JASO-FD is recommended." Most people read this and think this statement means it is JASO-FD, but its not.
