Chainsaw vs Outboard 2 Cycle Oil

MESSMAKER · Aug 14, 2009

I struggle to see the logic in this. A 2 stroke engine gets a steady stream of lub. since it is mixed with the incoming fuel.It has almost no time to break down. I have used different oil in dirt bikes,chain saws,weed eaters and tillers. I have never lost an engine. Improper mixture(too much oil) will cause the engine to run poorly and foul plugs. The only way I would think it would make a difference is in an engine that is running on the bare min. of oil in order to extract the last tiny bit of power. The arguments about lubricants and the I.C. engine always end up with a little science, a little conjecture, some real world experience and a good bit of vodoo with a healthy bit of fear spread about.

I see your point, but I would never run outboard oil in a saw unless it was labeled for use in air-cooled and water-cooled ala TCW3. Even then, it would be my cheapie Poulan "Wild Thingy" and not one of my real saws. In the scheme of things, oil is cheap....

Most outboards are water cooled and most chainsaws air cooled (run much hotter.) In general it is poor practice to use oil intended for cool running in a much hotter engine and vice versa. I have even read this in the engine documentation (Husky, I think.)

Used ATF filtered or not... gag a maggot what an incredibly dumb idea!

Everyone knows bacon drippings are the way to go for two stroke oil and if you run short you can substitute cod liver oil. No joke, I think I read this on some blog somewhere.

The bacon drippings reminded me- there actually are scented additives for fuel. I'm partial to the cinnamon myself

Girlie man!!! Cinnamon???? Nothing better than drippins from hickory smoke and black strap molasses cured bacon. Some of the rind stuffed in next to the drive sprocket will help keep 'er lubed up too!

Just lay the breakfast bacon on the manifold. Can of beans along side.

I can understand "wanting" to be frugal use that gallon of oil, but the best thing to do is to trade it or just give it to a friend. Cast your bread upon the water. Pay it forward kind of thing.

No way you should use 2 stroke oil, designed for a water cooled engine, in a hot running, air cooled engine. The ash differential is important too.

Would it kill your chainsaw in 10 minutes of use? no, of course not. But my goodness, you can buy store brand air cooled 2 stroke oil at any big box for so cheap. Makes no sense to be penny wise and pound foolish. Just my $.02

I have used 2stroke oil in my chainsaw for years. I bought a new chainsaw last year and have been useing it in that. Reading what you guys have to say has me worried now. I'll read the lable and if it doesn't say to be used in air cooled engines I will buy an oil that does.
The first chainsaw I had said in the instructions to use motor oil and gave the ratio per gallon. That was about 40 years ago.

We had Jeeps from the 60's till late 80's(Dad did). In the 70's AMC/Jeep had a newsletter that came out a few times a year. They had some recipes for cooking on the intake or exhaust manifold. Never did try them though... Sure it would work though. Most were supposed to be foil wrapped "dishes"
