because that is what my brother wanted to try in his 361 today (him and I went out and cut some). So... I was there. It was with me. It wasn't raining quite yet. I had another new chain. So I ran it.


On a different note - The nice thing going forward is that I am just going to start with 32:1 and stop if 40:1 is for sure slower or hotter or doesn't run as well.
 
Is it worth using?

seems good. actually formulated ...well says good with stihl saws on the bottle or something. I'd like to test it some more and see if the temps and times go down if using 32:1.

Don't know why but Hp2 & R50 seemed to also run very well at 40 and 45:1. Maybe the high viscosity #s? Fastest times were still at 32:1.


- looking over my notes - 2r @ 40:1 & k2 @ 40:1 ran like r50 @ 50:1 and hp2 @ 50:1.



Didn't your older tests make best power at 50 to 1 ? or was that a reset thing ?

that was ultra 50:1 vs 40:1 and h1r. So don't know what to tell ya there. I'll test h1r one more time.
 
Looks like all within fractions of a second ? so pick your favorite color and go with it ?



If you want to simplify and make light of hours and hours of work down to nothing and say there is no difference. I don't care.


But IMHO if you take in all the factors. Times, temps, how it ran, that it ran well at other ratios. The high visc #. How the other oils performed at other ratios. yeah. Hp2 is the winner of THIS group.

And I am not the end all be all here. Go buy some and try it. Run your own tests...report back to the thread.

You might say that.
You might also say on another day the results would be different.
This isn't to make lite of your labours, but all of these oils are so close really there is no meaningful differance and I suspect if you ran the same tests multiple times you would get multiple results. They are that close.

I can feel differences in how the engine runs with some different brands ,besides the times recorded were you happier with how some brands pulled under load ,clean response etc with one over another ?

I don't buy the this oil feels better than that oil thing. I think it's all in most guys heads.

I've considered all the factors at play and they aren't. Sorry.

And don't say I am biased either. I never would of thought 32:1 would be fastest. I thought the lower visc oils would of been fastest.

Ok I guess I wasn't clear enough in earlier posts. So here goes.

YES. Hp2 CLEARLY RAN THE BEST.

I think 2r had the least amount of torque when I was cutting firewood. Low visc? I don't know why...nor do I even care.

I think R50 and Hp2 had the most torque while just cutting. Cookies are one thing but actually cutting wood...yeah those two had more torque. Sorry they did! It seems crazy to say that, but I literally thought the chain was dull when I was cutting with 2R 40:1. And then it happened again with 32:1 2r. I was like what the hell.

I think R50 smells like a some nasty perfume or something. I can't stand it.

I think R50 @32:1 makes the saw run sluggish when you push it via multiple cuts. Yeah it got better at 40:1. But why in the hell would you want to use it, when u can use something that acts better at 32:1? Personally I think it's the high flash....so high the oil doesn't burn off. But who the hell knows for sure? No one here, that's for sure.

I think 2R screams at 40:1. I think K2 screams at 40:1. Saw feels lean. Solvents, less oil in the bottle? I don't know anymore nor do I care! What I do know is that the saw screams at 40:1 with those two and it ran like crap. Sorry bwalker it did. It ran so crappy that I wouldn't even try 45:1 let alone 50:1 in either of them.

and No I don't favor honda hp2. The only reason I even knew about it was because kenjax PM'd me or I pm'd him asking about it because he posted about itor something...anyway he said it ran really nice and he would send me some, which btw, he didn't.

Don't believe me? Guess what I DONT CARE! HP2 won here and if you don't like it, and yer all butt hurt about it. Again I DON'T CARE!
 
Again I'm glad you did the test and shared it on the site, and hopefully you had some fun running you saw.

I do however agree with bwalker, the times are well whiten the with margin of error that exists. Yes feeling a saws is stronger is totally unreliable, I've proved my own opinions wrong many times with a stopwatch.

As I expected you wouldn't see any real difference in power between the oils. Testing the real quality of each oil would require a test cell, dissembling a new saw, measuring the inertial components, adding internal temp sensors, running 50 gallons of fuel through the saw in the test cell, than retaking all measurements.

Man I appreciate the work u have put in ! Heck I bought HP2 to try yesterday even. Man this stuff is gettin to u and u should go to your happy place whatever that may be and rest your nerves alil. Appreciate all the work though man

People including engines builders some with decades of experience told you what was what, you didn't listen, and you still don't know what you're talking about. I'm not trying to attack you and I never was, but you resisted the information you were given, and did so arrogantly. There was no clear winner, in any way shape or form.
