Not having a boat, I never knew there would be a 2 cycle oil for them and
another for the air cooled engines.
I looked at the Coastal oil you showed a pix of. It has both a boat and
lawnmower on it. Site says it is good for all 2 cycle engines. Maybe it is
and maybe not. Some oils seem to be rated for both. I don't use enough 2
cycle stuff to make any differance in the price of the oil mix. I doubt I
use a gallon of the oil in a year or two. I noticed on some of the oil
bottles say they have addativies in them that act like the Stabil to keep
the gas fresh longer.
I do use the gas without ethanol in it and it seems to make a differance in
how smooth some of the engines run and not gum up if not used for a long
time such as my tiller that only gets used once or twice a year now. While
I use most of the gas up every 2 or 3 months, I put the Stabil in it just to
make sure. Probably not needed, but that way I know if I have some that is
not used for a while it will have a chance of being good.

I always look for prosumer model, one straddles between pro model and
consumer model. Price is in between too. Most polular saw in our neck of
wood is Stihl and
Husq. Echo was now gone way side. They keep changing models and service
parts availability is difficult.

"Forget about using TC-W3 oil, as it’s designed for water cooled engines
that run at low RPMs. It will work in a pinch in chainsaws, but long
term it’s not good for them. If you’re buying from a store that doesn’t
specialize in chainsaws, be sure to read the fine print on any bottle
Like an auto parts store (where I bought the TCW-3 oil, for something a
lot less than the $80/gallon that Lowes & Home Depot sell two-stroke oil
The problem, of course, is that we don't know HOW to get 2-stroke oil
that should work, as we don't have any *rating* for chainsaw oil.
I wonder if air-cooled motorcycle engine oil is the same as the stuff
we're supposed to put into chain saws?
Is there a *rating* system that we could look for that would tell us
which oil is suitable for air-cooled engines?
We know it's *not* TCW-3, but we don't know what it is.

I had googled forever the difference between the Stihl and Husqvarna, and
had gone with the Husqvarna because for the same $400 I could get a
slightly better saw at the time.
What I *love* about the Husqvarna is how easily it starts!
The Sears Craftsman (Poulon) 358.351800 was miserable to start and keep
running even when it was brand new.
Actually, truth be told, I do much the same thing.
I keep the small 2-ouncish 40:1 bottles around, and I keep
filling them, and using them with a gallon of 87AKI gas.
I figure, if some is good, more is better (to a point).
The factory manual picture was posted.
It has three lines, which, paraphrased, are:
1. Use Husqvarna oil.
2. Don't use TCW-rated oil.
3. If you can't use Husqvarna, use the equivalent.
Overall, that tells me nothing useful (other than TCW is bad).

I just called Husqvarna back at 800-487-5951 and got a few numbers
to call for my zip code (because they couldn't answer my question).
Calling those numbers, I've found that the RATING for the two-cycle
oil that is used in chainsaws is apparently JASO FD &/or ISO-L-EGD.
Googling, I find this specification for two-stroke oil:
First off, it says TC-W3 obsoletes TC-W & TC-WII (but, we already
know we don't want TCW-anything according to the owners manual).
For the JASO FD spec, we find the following:
1. JASO FA
– original spec established regulating lubricity, detergency,
initial torque, exhaust smoke and exhaust system blocking.
2. JASO FB
– increased lubricity, detergency, exhaust smoke and exhaust
system blocking requirements over FA.
3. JASO FC
– lubricity and initial torque requirements same as FB,
however far higher detergency, exhaust smoke and exhaust
system blocking requirements over FB.
4. JASO FD
– same as FC with far higher detergency requirement.
For the ISO L-EGD spec, we find it refers right back to JASO:
– same tests and requirements as JASO FB.
– same tests and slightly higher detergency
requirements (piston varnish) as JASO FC.
– same tests and requirements as JASO FD
I'm gonna print this, and tape it to my chainsaw box, along
with the existing chainsaw specification list as a reminder:
Husqvarna 445 18"
narrow kerf bar (aka micro lite, pixel)
72 drive links
3/16in file (4.8mm)
85°, 30°, 10° filing angles
Use H30, G72, 95VPX072CK chain
Do not use the H72 chain!
8.8oz bar oil per fill
16oz 87AKI gasoline per fill
10ml,1/3oz 2-stroke oil per fill
Only JASO SD or ISO-L-EGD oil
2.5oz oil per gallon gasoline

Here's another article, which mentions that JASO stands for the
Japanese Automobile Manufacturers Organization (JASO) and it explains
that JASO SD is the best currently, while ISO-L-EGD is a bit more
international, including American, Japanese and European engine
