Kawasaki K-tech OPE oil.
Kawasaki Racing 2-stroke (semi-syn, ashless)
Castrol RS 2T
Motul 710
Spectro Platinum SX-2 (least favorite but performs great)
Mobil-1 MX2T (still have 2 qts and will miss it when it's gone).
Klotz BeNol (super thick 15cSt miracle lube)
Blendzall #460 racing castor (likely the best oil in the world)
I have a $5 gift cert for O'Reilly that I plan on buying a quart of Lucas Semi-syn oil with. When the company can't even spell correctly the ratings that the oil supposedly meets I tend to not put much faith in the product. I'll try it for being nearly free though.
Any info on what the viscosity is at 100C for the Kawasaki oils? I looked around and wasn't able to find an MSDS on either of them nor any other technical data. Why was the Spectro oil the "least favorite" specifically? Also, have you tried Lucas Semi-Synthetic 2 cycle? Been reading a lot of great things about it even though it is a thinner oil (7.5 cst@100). Believe it or not it seems like Pennzoil Marine is legitimately useable in air cooled engines as well, never tried it myself though. From what I've gathered, the oil most comparable to what was considered the best (long discontinued Mobil 1 Racing 2T) that's currently available in the US is Maxima K2.

(just a guess) One reason why a two stroke oil could be labeled as "Mufti-Purpose" is that they contain a higher quality base stock that doesn't require an ash producing additive package. That way it can be used in air cooled as well as water cooled engines. Another guess is that most people aren't sure what they need, and most likely the TCW-3 oil won't hurt.

Figured I would jump in here with a different perspective.
I fly 2 gasser helicopters that run consistently in the 12500-14000 rpm range and don't get even close to the amount of cooling and airflow that air engines do.
I have been running pennzoil marine (this EXACT oil in question by the OP) for over 2 years. Both my engines are $500+ modified engines by TRM (Toxic Racing) and BH (BH Hanson). Both oils have been tested and BH Hanson even recommends it as an option.
The Oil was originally tested and verified to work exceptionally well by Chris Bergen of Bergen RC Helicopters and has been used and is currently being used by a very large segment of the Gasser RC Heli Community. You can do a search at Helifreak and Runryder.com and see that this oil has undergone some serous discussion and scrutiny.
I am currently running it in my DLE35RA and have had the engine apart and it looks wonderful on the inside...just like the rest of my engines.
The ONLY complaint I have ever had is that it does build up a small amount of carbon. BUT, I have yet to find an oil that doesn't. There are many variables to that and, per Al at TRM, a small heart shaped carbon pattern on the top of the piston is normal.
In summary, using this oil is perfectly fine. It runs exceptionally well and WILL NOT damage your engine. If you are concerned, as others have stated, there are tons of oils out there to choose from and at the end of the day, if it makes you feel better, go with something else. BUT.....you can run it and your engine will be perfectly fine.
Anyone who states anything negative about it is simply misinformed or offering pure opinions. We all have opinions, but my statements and results are based on facts collected and experienced by myself and experts in the RC engine industry...not weekend worriers with a keyboard and a mouse.
To answer the OP specifically: PENZOIL Marine full synthetic is GOOD
