is it just a detergant thing or what? I ask because universal is generally found it quarts but outboard is easily found in gallons, which would be nice to carry around for mixing my diesel fuel with.

I dont know how it afects us useing it as a fuel suplement, but it will ruin a 2 stroke moter if used wrong. You can use non outboard oil in an outboard,but you cant run outboard oil in a 2 stroke motor. Like a chainsaw or lawnmower. Hope this helps. Rod

Recently picked up a gallon of Supertech outboard motor oil from Walmart. It states that it's meets requirements of Outboard motors, chainsaws, weedeaters, 2 stroke mowers and other 2 stroke equip. Can be used in Injection or pre mix systems. It also meets the TCW-3 spec which is the good stuff. Can't remember the exact price but it was a little over $8 a gallon.

yeah, thats what i was looking at, and thinking about?

I believe two stroke oil is two stroke oil. Some outboard motor companies, for example, mercury and evinrude/johnson put extra additives in their oil for their specific needs. That is why you pay more for the engine specific name brands. The only thing that matters is the ratio that you mix it at, like 50 to 1 or 25 to 1 etc. Also the fact that it meets the TCW-3 spec.

They now have fully synthetic 2 stroke oil. I guess for the same reasons that we use synthetic engine oil. It is much more expensive!

My Husqvarna saw seized a ring due to using TCW-3. If you don't believe it; go ahead and use it in your $800 saw. TCW-3 should only be used for liquid cooled applications regardless of what the jug says.

Thanks for the heads up and both of you are correct.

I just checked my Stihl chainsaw manual and is says " Use only Stihl two stroke engine oil or equivalent high-quality two stroke engine oil designed for use in air cooled engines. Do not use BIA or TCW rated two stroke oil (for use in water cooled engines). " Now why the hell would the Walmart brand say otherwise?
I usually buy all my Stihl equip from one dealer. They recommend and sell OPTI-2 so thats what I've been using. Says nothing about the TCW-3 spec. Suppose to be good stuff. Hope so.

Anyway, the Walmart oil should be good to mix with diesel. The TCW-3 is suppose to be the latest spec.

I guess the yamalube should of ruined my saw by now. Guess I got lucky.

You can use non-detergent motor oil for 2 cycle applications. That's all my grandpa ever used, and I've done it all my life. Never had a single problem with it. You can get it at tractor supply pretty cheap in sizes up to 5 gal buckets.

timberwolf, non-det engine oil has ash that will gum up rings. that is reason 2-cycle oil was manufactured. saw web site that explained between universal(air cooled) and TCW-1/2/3(two cycle watercooled engine). air cooled flashes off quicker as i remember it, tcw lingers to coat inside engine parts, due to opearating in water enviroment. either should work fine.

 

[Timberwolf530]

Well, I've got a Stihl chainsaw that's around 20 years old, and that's all it's ever had run through it. I guess it can't hurt it too much.

I don't know exactly but I really like Opti-2 oil in my Husqavarna chainsaw and brush cutter/weed eater. Seems to last longer and not gum up the carb better than the other stuff. Smokes less too. I really like the stuff. It was recommended to me by a good small engine shop mechanic owner operator. I'd say thats the best oil to use. The only problem is its a little tougher to find and more $.

My take is the marine grade 2 stroke oil (w) is for water cooled engines where engine runs cooler. Other things to think about is today's outboard engines with high tech injection systems have more stringent demand for premium clean fuel. And emmissions regulations for marine engines is also getting tougher. Right now I think TCW-3 is good for diesel but will do more research.

Here is decent article I skimmed it / read it really fast but seems informative.

I'll agree with guybb3 and a bear. I'll stick with Stihl brand 2 cycle in my 3 011AVT's , 029, 440, and 060. With an average price for the lot of about $400/saw I'll stick with the manufacturer recommended lube for their motors. 2 of the 011's are 20 years old or older and the only major engine work they have needed was a carb rebuild last year.
