out board oil..?

I just read up on the TC-W3 spec and much of the performance criteria has to do with corrosion resistance, emissions, and other marine based needs.

For their testing, they run an outboard 5 minutes at idle, then 55 minutes WOT (Wide Open Throttle) 98 times...a 98 hour test, then take the motor apart for inspection.

 

Of significance, I find that they are using comparatively low performance engines for their 98 hour test procedure. I consider a 913cc 70HP motor that redlines at 5000RPM an unstressed engine in comparison to our 65HP 350cc 9500RPM (average for a base line) motors.

 

Anther point is their water temp output spec of 130 degrees...ours is somewhere closer to 190-200. I'm sure this temp variance is a consideration in the formulation and design of the oil package.

 

Finally, they have to meet EPA requirements for clean burning emissions to satisfy Federal regulations. This probably isn't best for your motor, but better for the environment.

 

My opinion is that because outboards run significantly cooler than your Banshee or Weed Wacker, the oil will burn off earlier than you want it to...resulting in insufficient lubrication at some level.

Also, we run a motor that is 1/3 the displacement size at twice the RPM as the test outboard motor...so our motors are stressed 6 times greater under load than theirs.

 

So the difference in operating temperatures as well as the low performance engines this oil is designed for, and the prioritization of emissions output mandates would make me decide NOT to use TC-W3 Outboard oil in my 'Shee now that I know better.

 

When I was a kid, I used Pennzoil 30W automotive engine oil as 2-stroke premix oil in my POS mini-bike and it worked as long as I had it. Would I choose to do that now??

 

That is the question you have to answer now!!

 

Hope that helps...Jay from SanD.

 

BTW: It sucks that I can go to West Marine and buy a 2 1/2 gallon jug of outboard oil for $19.00...about the same as 2 quarts of 2R!!! You know we are gettin' hosed....

I used it for years. Blew two motors on it also, were they related? I don't think so. One was a piston with a hole in it, the other was when a skirt shattered into my bottom end.

 

Too bad no one here has a spectrometer. Then we would know the REAL difference.

I have a 2003 Banshee and I run Super Tech TCW-3 oil (avail at walmart) mixed 32:1. I have run it since day 1 in this quad without any issues. It actually burns very clean. The motor is still stock (with exception of cool head), and has never been opened up, not even for a ring change. I have ridden this quad twice a month (3-6 hrs a day) since I bought it in 2003. I have used blendsal, klotz, maxima, yamalube, in my other banshees and thought I'd give TCW-3 a try in this one. This motor has way surpassed the maintenence of all my other banshees. I used to do a top-end every 1-2 years. I also always run a clean air filter. I have never suffered a bottom end failure in any of my bikes. I give the TCW-3 a thumbs up....but this is only my opinion.

outboard oil is design for COLD running 2-stroke engines, outboard motors get their cooling out of the ocean or from the source they are used in, so they run very cold, operating temp of 122F. Your Banshee is a hot running 2-stroke motor, so you need oil to protect it in very hot circumstances, while outboards need oil to protect and do the job in more colder situations. That does not mean that outboard oil cannot protect a hot running engine, but as far as I know, their not design to do so, or especially not so good than the non outboard oils we use in our banshees, so why risk using outboard oil?

I have always run this tc-w3 oil in everything. the stuff i use isnt the cheapest stuff i can find or anything. it works out to like 6 bucks a liter when you buy a case of it.

 

nowhere on it does it say outboard oil. it has a picture of a sled, a dirtbike a quad and a boat on the bottle :shrug:

 

i ran it in my 125 and raced motocross with it, and ran it hard on the logging roads too. every time i tore it down it looked perfect inside.

the only time it ever blew up was after about 5 miutes of wide open 5th gear down the road. it seized the connecting rod to the crankshaft, but the cylinder and piston still looked good.

 

this is my experience with it.
