What are the benefits ?
I have found that both Dominator & Red Armor run very clean & wet the engine well with sufficient puddling within the crankcase . Red Armor really deposits a nice red sheen on Piston bearings & rods surfaces . Saber is fine however just a little soot on the crown & exhaust ports , nothing serious , ring lands are clean . Just a observation on all saws that I currently run !

what do u guys think about this articel?

More oil more power, do u find similar results?

Rings don't seal very well without oil that goes for 2T's and 4T's
An easy way to see this in practice is do a compression test on an old worn out chainsaw with low compression or any engine for that matter.
Then redo the compression test but this time put some straight oil down the plug hole you will see a rise in compression.

A lot has changed in oil technology since 1978. I know this was being tossed around as an updated oil test using some saws on a dyno. The fact that auto tune saws don’t like some heavier ratios probably is the biggest proof that it’s probably not going to be the case with OPE. I think the carb jet physical size, lack of reeds in most cases, and lack of displacement (250CC is what was tested) will be the reasons why.

More oil could possibly make just a little better seal. Ran some old marine two stroke oil in a small 4 cylinder pickup for a bit. Thought it helped with oil consumption. No idea I’d it honestly did or didn’t. My mind goes places sometimes


I added the oil to the fuel

Can't pick and choose your theories, gotta stick with the givens, including "oil technology"

Oil seals rings !

There is no "magical oil" out there, but there are a few that deliver great lube, corrosion resistance, minimum to no deposits, performance, and smokeless discharge. Two that come to mind are Dominator and Schaffers 7000. Those are the only 2 oils that I will ever purchase again, everything else, to me, just isnt worth it.

Schaeffer’s 7000 ran for (?) hrs in my MS 460 since the new piston was installed back in Feb/March this year. I mix 40:1 with 91 octane non-ethanol fuel. I use this saw almost daily as a hand-cutter logger in hardwood country, the upper midwest. Typical day is 1-1.5 gallons of fuel used.. Saw is not stock, squish was set to about .024” by using a Coors beer can as a gasket. Timing was advanced, and muffler is a hogged out dual port style. Saw is strong.

Although I don’t really care for the layer of carbon on the top of the piston, the cleanliness of the rest of the parts, and the light layer of oil speak for themselves.

Yeah using that Coors can for a gasket leaves a lot of carbon on the piston! LOL You need a beer with more percent of alcohol!

I don't know much about saws, or oil, or saws and oil, but that looks crazy to me. Is that normal?

Maybe it is from a really hot piston and really cool cylinder from running hard in the middle of winter? :nusenuse:
