You can run almost any oil in a pinch in those engines.
Better than straight gas but not made for air cooled two strokes.
It's best to run an oil made for air cooled equipment. They run much hotter than water cooled outboard boat motors and oils made for water cooled equipment will leave hard deposits in an air cooled motor.
On the other hand, saws AND boats, ran for many years w/non-detergent 30W at 20:1.............
That was back when saws (and the operators) were built like tanks.
And 95% of the cars/trucks you saw were made in USA.
I wouldn't do it. The marine 2-Stroke oils are formulated for an engine running at a much lower operating temperature. Air-cooled engines need a different 2-stroke oil for higher temps. Stepping over dollars to pick up pennies...

The right stuff is so cheap and so available, I just don't see any reason to experiment with anything else.
And doubled as a Wasp smoker in a pinch.

I suspect you're gonna get a lot of ash/carbon if you use TCW-3 in an air-cooled engine.
I don't think TCW-3 is made for the temperatures that air-cooled motors can get up to.

I don't know much about any of this, so am asking, how would you get carbon from running this oil
in a non boat engine, and not have this carbon in the boat engine.
According tho Amsoil it runs super clean and up to 250hp
Outstanding Wear Protection
The elevated heat and friction of modern two-stroke marine motors can exceed the film strength of inferior oils, increasing the likelihood of scuffing and wear. HP Marine's exclusive synthetic formulation provides increased lubricity for reduced wear during normal and lean-mix operation (see field study results). In 534 hours of field testing, HP Marine completely prevented piston skirt and cylinder bore scuffing, demonstrating its superior lubricity and ability to reduce friction between moving parts. It maintains a strong lubricating film even in lean-mix, severe-service conditions, helping marine engines achieve maximum life.
Excellent Deposit Control
HP Marine is formulated with MAXDOSE™, a system of advanced additives for "super-clean" operation. It helps prevent deposits that lead to poor performance. In field testing, HP Marine inhibited ring deposits that can cause ring sticking and ring jacking (carbon buildup behind the ring, forcing it outward), a phenomenon that occurs in modern DFI outboard motors. It also virtually eliminated exhaust port deposits for reliable, efficient operation.
Proven in Marine E-TEC Field Study
HP Marine was installed in a 250-hp Evinrude E-TEC engine powering a heavy-duty marine rescue vessel. Following a 28-hour break-in period at the normal oil setting, the engine was programmed to its factory-lean setting and operated for 506 hours prior to disassembly. An ASTM calibrated rater examined and awarded each component either a merit rating on a scale of 0 to 10 (with 10 representing no distress) or a percentage rating (with 0 percent representing no distress). Results prove HP Marine provided exceptional wear protection and deposit control. For complete study results, visit amsoil.com/proof.
Carbon and ash are secondary issues. The real problem is that the engine temperature in an air cooled chainsaw is significantly higher than a boat or PWC with lake water cooling. We are trying to save you some grief. There‘s a reason that TC-W3 oil states: “For water-cooled marine engines“. It’s certification is from the NMMA - National Marine Manufacturers Association.

TCW3 is technically an "ashless" oil by design, and has a different additive package vs. other 2 strokes. A water cooled outboard has much lower engine temps than an air cooled chainsaw engine, they run at a lower RPM, and are cross scavenged vs. loop scavenged. Long story short, use TCW3 in outboards and JASO FD in everything else. Will it blow up? No, but the right oil is cheap and available, so why chance it. Also, I take everything Amsoil says in their advertisements with a grain of salt.

Higher temperatures in a non-water-cooled engine.
Theoretically a water-cooled aluminum engine isn't ever going to get much hotter than 212°F -- the boiling point of water. I suspect localized temps in a chainsaw would be a smidge higher, causing the oil to start to scorch/carbon up. Bad juju if the rings get jammed up with carbon...
As for the Amsoil ad copy you quoted...well, it's ad copy.
Just use the right oil and forget this! Be done with it already and go work.
So sell it , everything is selling good right now with all that went on.
It's still not the right oil for your saw.
Nuff said!
