Another 2 stroke Oil Question TCW3
Brian McGarry
$12.00,
to use in a 150 hp water cooled 2 stroke boat outboard. Why can't I use
it in
my water cooled 2 stroke dirt bike? Common sense tells me, that if the
outboard
engine industry recommend this stuff, it must be pretty good.

cooling capacity. They tend to run at very controlled temps because of this.
Bikes on the other hand have very small cooling systems and tend to run
hotter. Many outboards now have direct injection instead of using premix
too. While I cannot answer your question directly the above things may
affect the lubrication requirements of each type of motor to make using
outboard oil a bad idea.
I used about $50 of Klotz synthetic oil @ $8 per quart in my bike last year,
I consider it cheap insurance to ensure my bike keeps running right and
wears as little as possible.

RM250 since new. There's something in me that just can't give $8 for a
qt. of oil.
I only trailride and my jetting is spot on.
I put a new top end it for the first time last year, not because it
needed it, just because. The old piston look great. after taking all the
cylinder bore measurements,
decided to go back with stock size piston
as an oversize would have been too tight.
I run it at 40:1.

impression of this group. Just spend a buck and half more and get the right
oil! You don't have to buy the top of the line synthetic, because if you
wanted the best you wouldn't be buying boat oil. Just get 2 stroke oil for
motorcycles.

I remember from owning jet skis and looking at the difference in oils
that watercraft oil has a different ash content. Don't ask me what
difference that makes.

system since they are cooled by the water they run in. Also, if you pour
outboard oil and 2 stroke motorcycle oil side by side on a flat surface you
will notice that the motorcycle oil is thicker for better protection. Just
break down a extra buck or so and get the right stuff.

in there world record holding 2.5 efi mercs
output 280-400bhp at prop.7750-11500 rpm
depending on class.most stock outboards
turn 5000-7500rpm depending on model.
outboard oil is designed for lower temps.
will leave increased deposits on powervalve
and in exhaust pipes.

synthetic and works very well in my buddys
11.6 /110 mph allison-merc.2.5efi drag ss
(300bhp stk-360bhp mod@prop add 10%
for bhp@flywheel).boat oil should work fine
for non-powervalve playbike.if you race,have
powervalve,or aircooled engine use HQ MC oil.

your average MXer? What kind of RPM do they turn? (I don't know, I'm
just throwing out a few ideas.)

I think my brother's Merc 200 turns about 7500. Maybe not that much though.
Sure sounds good when he's flushing it out. 6 cylinder 2-stroke, oh yeah.

gallon. I have 2 CR250s and 3 ATC 250R and run it at 36 or 40 to 1. The
group I ride in has 2 CR125s, RM250, 2 CR250s, 2 KDX 200, 220, and a
CR500....we all use the above mentioned oil.
When the oil was bottled under the ITASCA name (by Quaker State), I called
the factory and spoke to the 2-stroke oil tech. His official stance..ie the
company line, was that ...it meets all TCW3 standards and that it would be
ok to run in a motorcycle. He also stated the company line in "...mix it
at the manuf. (cycle manuf.) recommendations....." I told him that Honda
recommends 20:1 (on the ATC 250R).....finally after I asked him to talk to
me like his neighbor over the back fence, he gave me a bunch of real
interesting info.
just a few of what I can remember:
1. TCW3 has 10-15 different standards (lubrosity? at high rpm, film
strength, coating strength, non-running coating, ( I can't remember all of
them or even the correct terms) He said that even the standard TCW3 oil
they make (Wal-Mart "Tech 2000") meets those standards. The syn. just does
that much better.
2. He said to pass the TCW3 rating the oil must provide a pre-defined (high
level) of protection at 100:1 in an outboard running at 6000 rpm for long
period (don't remember the exact time frame, but was long enough to satisfy
me.)
3. He recommended to me to not run the oil that thin because the
non-running coating would not be sufficient to keep rust and other oxidation
in check. He said that 50- 60:1 would be just fine...I run it thicker so
the rings seal better.
4. He said that most of the "trick name motorcycle oils" do not meet any
standard. These oils could what ever protection the oil seller "thinks" is
ok.....the TCW3 standards test are quite expensive and most smaller,
specialty oil providers choose not to spend the money.....or can't live up
to the standards?????
Flame all you want if you don't like what I stated, you see...when you get
old....you don't remember all the details or facts, just the final
decision.....and a good decision it has been......I have more money to buy
....more toys.....

brand oil. I realize that racing oil is over priced, but sometimes you get
what you pay for. What kind of riding do you do. I race motorcross and am
constinately running my engine at redline. I use MAXIMA 927 racing oil, and
i have never blown a motor. I am having my motor rebuilt by a professional
builder this year and he told me to use maxima oil in my lt250r. I dont think
he recomended this brand so i would waste my money. I can afford a few extra
bucks to ensure my motors protection under "HIGH STRESS" riding.

wal-mart
> brand oil.
No... wal-mart oil is not my oil...I just use it and have great success.
What kind of riding do you do.
I ride desert in AZ and dunes in Glamis. I am not running my CR250 toooo
hard, but the 125s do run hard in the sand and on the long stretches in the
desert. Can't say if it is harder than motorcross.
Hey doesn't the 927 have castor in it?? If so please keep using it ....I
love the smell of castor at the dunes.

I agree with the PV part. A buddy of mine ran the WalMart TCW3 in his 98 KTM
250 E for it's first year of life at 40:1. Upon tear down, the powervalves were
a horrible mess. He ended up buying new ones after spending days trying to
clean them.
He switched to MC oil after that.
