YOUR CHAINSAW HAS A TWO-STROKE ENGINE. So what is the problem?

I'll admit, I've no idea why is this a
concern. Is that outboard motor oil?

Drat, what?

Incidentally, not seen you in a couple days.

Under the header "Fuel Handling", and the tag "Two-Stroke Oil".
It says:
- Never use two-stroke oil intended for water-cooled engines,
sometimes referred to as outboard oil (rated TCW).

I hate it when things say not to use something but they don't say why,
but, it's there, so, I've clearly been using the wrong oil.

Googling, I find this ruined engine, reputedly due to the oil:

One of the few things I remember from the small
engine course I took, the outboards are water
cooled, and they run cooler. Air cooled like your
saw runs 100 degrees or so hotter. it's very wise
to keep the saw clean of dust after each use, and
try to clean the oil and crud off the cooling fins.
At least, that's what the guy said.

TCW3 is not an oil rated for the temperature a chainsaw operates at.

I guess that means the TCW-rated oil doesn't "cool" the engine as well as
whatever rating it is that I should get.

It is not going to blow up right away but you will see more wear than
you should, in theory.

Makes sense, if the engine isn't being cooled right.

If this is a Homelite or Ryobi, you will probably throw it away for
other reasons before the engine actually wears out tho.

It's a Husqvarna 445, but I think it's the same oil I had used on a
Craftsman (aka Poulon) chainsaw, which ended up siezing on me just after
the warranty period expired.

When they took it apart they said it had scored pistons, and I asked what
I could possibly have done to score the pistons after just about 10 uses.

Please consider pour that gas in your car
(or your wife's car) fuel tank, and buy
some oil that's rated for the saw.

Hope your saw's not badly damaged.

I can appreciate your concern BUT did you see the machines on your oil container? Doesn't that tell you pretty well that it is an ALL-PURPOSE type oil?

That's what I had thought too.

But, only recently, did I notice the line "Never" to use TCW-rated oil
in the owners manual for my 18" Husqvarna 445.

Bear in mind, my first chain saw ever, was a Craftsman (aka Poulon) 18"
chainsaw which died in about a year of just occassional use.

When I had it taken apart, they told me it had "scored pistons".

I had used the exact same oil, and nobody used the chainsaw but me, and I
did NOT abuse it. Yet, it died, all the same, after only about 10 uses.

In fact, the only thing I could save was the black plastic chainsaw
carrier that you see my Husky in, in my photo below.

My concern was mostly that the prior chainsaw lasted fewer than a dozen

All of a sudden, the engine started speeding up faster and faster and
faster. I didn't realize what was happening until it was too late.

After about five or ten minutes of that speeded-up-engine, the engine
never started again. When I had it looked at, they said the pistons were
scored, and that it would cost more than it's worth, to fix.

Maybe it was the oil?
https://c3.staticflickr.com/3/2949/1...768e79a2_c.jpg

I don't know. But I never abused that saw, and it barely lasted.

I swore I'd never buy another Craftsman gas-motor tool ever again, so,
that's why I bought the Husqvarna to replace it.

Saw, not bar. Around the gasoline engine, there
should be some fins for cooling. On my saw, the
starter cord turns the flywheel. The flywheel
has fins to move cooling air over the saw body.
Helps keep the engine cool.

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.

No, that is not the problem. You had the same problem that I had with
my Homelite saw. It was cheap enough to buy and I hardly use the saw so
it is good enough. A hundred bucks later, we know that is is NOT "good

Get a Stihl and be done with it. You will never need another saw.

One other thing Danny is your 50/1 ratio for your mix. I never run that lean...have always gone with 40/1 or even 30/1 in really hot weather. As long as it will start and run the extra oil won't hurt other than the heavy smoke.

Don't get a Stihl "occasional use" saw. They should not have the Stihl

Hi,
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
due to
parts availability is difficult.

I had a outboard boat motor that was air cooled, ~ 5HP - circa 70's or
so? Sears sold them (I bought it used) IIRC 2 cycle oil - same mix as
for a chain saw, perhaps the ratio mix was a tad different. Spark
plugs fouled if over mixed with to much oil, but it kept the engine
mechanics (piston, rod) well lubricated. The carb used a rubber
diaphragm, also lubricated, or it dried out and failed.

Maybe just a fouled spark plug no and then but they can often be
cleaned up, or replaced when needed. Carbon builds up on the top of
the piston too.

Actually, truth be told, I do much the same thing.

I keep the small 2-ouncish 40:1 bottles around, and I keep

I figure, if some is good, more is better (to a point).

Most motocycles do not mix oil in the gas, unless it is some of the small
ones.
You do not use the crankcase oil and oil you mix with gas in the wrong
places.

Overall, that tells me nothing useful (other than TCW is bad).

Gosh, it tells me to use their oil. Don't use the wrong oil. Or use
what oil meets the standard. What did I miss? See #3 and follow what
it suggests? Bean counter accountants may overlook the obvious

Get a Stihl and be done with it. You will never need another saw.

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!

Stihl is German engineering (quality), but also made/built in the USA.
I don't know about Husqvarna, et. al.

Hi,
Stihl, Husq, Jonsered are all good saws. Latter two are Scandinavian origin.
My grand son lives on Vancouver Island, when I visit there, I often see
pro
lumber jacks use monster size Jonsered saws.

Did you get to see Lumber Jills? I did while living in the Adirondack
Mountains of New York. Men were men and so were the women, sheep were
restless

Sample: _Chics with AXES_

"Cheer on your favorite Lumberjills as you watch these highly skilled
athletes compete in: Crosscut Sawing, Underhand Chopping, Axe
Throwing, Power 'Hot' Sawing, Chainsaw Carving, and Log Rolling!"

I just realized, when I bought a new gas can to mix a new batch of 50:1
two-stroke oil for my chainsaw, that I have been using TCW-3 two-stroke
oil for the past two years.

UPDATE:
H
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:
http://www.motor-talk.de/forum/aktio...hmentId=683876

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:
a. ISO-L-EGB
€“ same tests and requirements as JASO FB.
b. ISO-L-EGC
€“ same tests and slightly higher detergency
requirements (piston varnish) as JASO FC.
c. ISO-L-EGD
€“ 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)
0.050in pitch
0.325in gauge
0.025in height

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
manufacturers.
