Because every professional user I have ever seen is using 10W30 engine
oil. Now I'm not about to put that into my Stihls but I was just
wondering if I am wasting money on expensive bar oil?
I worked with a professional tree service for 7 years. We used the bar oil
or motor oil . Whatever was available at the time.. Using motor oil never
hurt any saw we had. We used Stihls, we had Huskys, Echos (long time ago).
Never hurt any of them. the main thing is to make sure that the bar gets
oil. Theres a slot that the chain runs in.. sometimes it's good to clean
that out. It can get gunked up a bit. That'll help keep the bar lubed up.
Used 10W30 in my Stihl from the time I bought it until it was
"borrowed" by an uninvited guest - about five- years - and it worked
well for me.

No, not really.
The suspended solids and other junk (such as combustion byproducts) in used
motor oil don't do either the bar or the chain any good. That gunk is better
off being recycled and disposed of properly.

I have never actually put used motor oil in my saws, although I have been told
that it can be done. I was just testing a theory
that if I said I did that Doug Miller would be the first one to tell me that I
was wrong to do so.
Theory proven correct ;^)
"if a guy doesn't figure he's as much of an asshole as half
the guys out there he prob'ly ain't thinkin so good" -alvin
What I see, most guys figure they are in the top 1% of "good guys"
or so! :(
Leads to trouble, one perfect little momma's boy dealing with
another perfect little momma's boy.
If they figured they were so "good" that they fit in the top 10% I
could go along with that if they were a fairy. I figure the top 10%
of "good" guys out there are all fairies. Are you a fairy? ;)
It's ok if you are, I'm not making a judgement on that, ok?
You judge yourself.
When a guy uses the word "proper" it kind of gives me the creeps.
That was my grandma's word and the way she saw everything, in terms
of "proper" or not. Never knew guys used that word until I got on
You find it kind of creepy?
Or is it just me? :/

Actually, that seems like a pretty good use for it. The claim that
'it doesn't do the bar any good" is probably true but OTOH it is very
unlikely to do it any harm either. After all, it was being used up
until it was drained to lubricate a far more complicated and delicate
mechanical system (your car) with no ill effects. To think that it
was good enough for your car up till then, but inadequate for the task
of lubing the chain and bar is silly. And it's an equally silly
suggestion that someone is doing the world a favor to recycle it
instead because that means you will be using BRAND NEW oil instead of
that used oil - clearly a net loss to the world of limited oil.
Probably no more than just being born. I know a guy who used old motor
oil for a number of things, from (he thought) preserving fence posts to
sun tan oil. He's been doing both for upwards of 40 years with no
apparent ill effects.
My objection to used motor oil on chainsaw bars is simpler. It is too
thin, likely to get flung off, and provide almost no protection. That's
the same objection I'd have to running it on a motorcycle, or bicycle,
That is it in a nutshell. I figure if the engineers designing them say
to use oil formulated for the use, then use it. I am sure that they
know one hell of lot more about it than I do. I would have to dig out
my manual on my new saw to be sure but I think it specifically says not
to use motor oil.
Specific warnings are one thing, (and of course, you have no idea if the
eningeers put that in, or if marketing put that in) but I can tell you as
an engineer that I'm most likely to reccomend that you only use a certain
stuff not becuase I know it's the best, or the only thing that's good, but
becuase people will go and pour concentrated sulfuric acid and iron
filings in and then complain about it.
If they don't say why, then you've got to take that with a grain of salt.
Of course, if you have no other opinons, you may as well do that, but I
know from personal experience that manuals are hardly the be all and end
all of the situation. They're only oocasionally even authoratative.
