661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[CR500]

Guy from a tree service company just left here ,his truck bed was full of silver stihl bottles ...........

his saws are sooooooooooo screwed lol


kidding I used to run Ultra like most people on here there was a time when a majority of people only ran Stihl HP Ultra,

Nothing wrong with it really

That's odd, they actually use oil. How about air filters? I hear a saw will gain a few rpm's without an air filter.

ever see a farmer maintain a saw? lol


More than a few are caked with dust and the occasional strands of hay.... gotta love round bales lol

well screw this - i'm gonna run a test...as soon as I can.

ported 661 vs my muff modded 661. 36" .404 new RS chains.

we'll do 32:1 42:1 and 50:1. H1R.

3-4 cuts, temp reading after ea cut. Timed.

Combo of steadiest & coolest temps & best times, wins! Should be interesting to see what works best in a ported saw vs stock saw.

Redbull straight heads up!!! Yamalube 2r vs H1R!!!

Dominator actually isn't too bad and I detest the Amsoil conpany.. I like 2R and have used it alot. I would try K2 as others I trust like it. NOT SURE ON baileys or silkolene. Would not run r50, h1r or 800.

I've heard of rust forming using Dominator because it doesn't have rust protection. The ester based oils at least list it on the bottle whether its in there or not IDK.

OIL!!!!

This Yamalube has me intrigued[emoji52]

This thread is like sore deek.......can't beat it.

by the numbers it doesn't appear to be anything special. http://www.arboristsite.com/communi...1-results-info-condensed.277566/#post-5305417

honestly the only thing that looks like it most closely mimics the #s of Stihl ultra is H1R. I also looked at specific gravity #s. There really isn't much to go on. But based on what there is. H1R most closely mimics stihl.

and clearly some of these are just hell and gone from anywhere to even close to stihl #s. as in it seems probable that some of them shouldn't even be used in a chainsaw!

Could be time for Farmer Steve, Homelitenut and Sagetown to chip in (or confess) here

How do you know lowest temp is best? If the oil combusts better, wouldn't that create more heat? Doesn't heat = energy? I'm just playing devil's advocate and throwing these out there off the top of my head. We don't even know if what we're testing for here really means what we think it does. Bigger, higher, lower, etc isn't always better.

Chain.......

It's really all about the chain.

Trooph.

 

[KenJax Tree]

Chains need oil too....what kind is best?

I said..
"Combo of steadiest & coolest temps & best times, wins!" Combo is the keyword. ie. the best combo of all 3. ie. if it's cool and slow than that's probably not the best combo of all 3.

What Brad's saying is how do you know if hotter isn't a good thing. Our vehicles have thermostats in them to keep heat in the engine. And obviously to let it out once the desired temp has been reached. Maybe 250° is better than 220. We don't know the upper limit where added heat is no longer desirable.

I think that is why he is doing these tests sir ,to see where the happy spot is .

Yep. I'm not disagreeing. Just saying that heat within reason might be a good thing. If one oil proves to be better for all other reasons, but it runs 20° hotter, that may still be 50 or 150° ???below that temp which is required for damage. I'm not for or against any of these oils. Just saying that I wouldn't necessarily eliminate one oil simply because of added heat, if that temp was never going to lead to damage.

And what do those numbers tell you?
