Fuel was fine.
How many motors ran on H1R have you tore down?
Quite a few, all of them high dollar 2 cycle aircraft engines ranging from 50cc to 150cc, I have not found an oil that works as good as h1r. There are other tests in the aircraft engine field that show the same results as the one posted .
 
Even if H1R didn't do wonky things to combustion, I still would not use it any more. No excuse for a oil to have deposits in the ring grooves like this. These sorts of deposits can and do cause ring mobility issues, which intern causes blowboy and premature failure.View attachment 424000
My milling 660 has deposits like this with h1r ,it has had a good amount of h1r ,run through it ,rich even ,black carbon with white/gray speckles ,
Here is a plug ,used for 2.5 gallons of fuel with a different oil ,still tuned rich ,but seems to burn pretty clean still ,muffler is dryer inside and not as sooty now ,piston has a nice coat of oil on it ,i want to see what this plug looks like after 20 or so gallons,am sure this thread will be going still in a couple months to repost after more fuel run through it ,lol milling cedar 5-11-15 429.JPG milling cedar 5-11-15 428.JPG
 
I asked Belray about H1R inhibiting combustion. The response -

---------------------------------------------
belray - H1-R is not meant to conserve fuel or to be an economical oil. Its purpose is to produce the most power and protect the best. It is a high performance race oil that protects engines running at their power limits and keeps them going at all costs. In bikes, the higher usage of fuel can usually be fixed through carb or injector tuning if that’s what the user wants at a performance cost. In saws, I don’t know.

The point is that it does not inhibit combustion. It just takes more fuel to run at that level. There is more energy produced by the engine and as the law of conservation of energy tells us, energy can neither be created nor destroyed. So more power equals more fuel.

me:
So some oils are formulated to conserve fuel or be economical? Curious how this is done...the short version please. :)

belray

We don’t concern ourselves with fuel conservation, and since we don’t do it, I don’t research it. I couldn’t tell you what goes into an energy conserving oil that makes it conserve fuel.
-------------------------------------
-------------------------------------
So based on that ...the only way to be sure on any of this crap is to test em.

I think I will test

2r - 32:1 36:1 & 40:1 maybe 45:1
710 - 32:1 36:1 & 40:1 maybe 45:1
sI-7- 32:1 36:1 & 40:1 maybe 45:1

800 - 32:1 36:1 40:1 45:1 50:1
H1R - 32:1 36:1 40:1 45:1 50:1

Just not liking what im seeing on R50 so I'm cutting it...

Hello, I'm wondering about using the R-50 in my chainsaw. It's a Stihl 661
91cc 7.5hp runs 13,500 off load WOT and say approx 9- 10,000 on load. (in wood)
Generally the saw is idling for a little bit and then will run 10 sec-1min
long cuts at WOT and then idling for a bit until the next cut. Idle =
~2800rpm.

Hello ,

The R50 is a great product for high rpm use, but most of your time would be at idle or at about 10,000 RPMs which would make me think that the 50:1 TechniPlate would be a better product for your application.
 
I aint a fan of the once in a while overwhelming smell of R50, but everything else about it is just perfect.

So far, 800 and R50 have given me the best running saws ........... smoothe idle, crispy response, power at the high end.

How much R50 would you need to do your test with it ?

It inhibits combustion and that's why it uses more fuel. Did you expect Belray to tell you anything other than their product is great...

The same logic used to cut R50 could be applied to all these oils.....

it doesn't matter what you think it does or doesn't do.

We'll run all the oils and find what mix ratio each likes. maybe it'll be 2R at 32:1 vs 710 @ 36:1 vs 800 at 40:1 and so on.

then run those against each other. See what differences there are.

When that happens...then there is something to talk about.
 
For shitsngrins, last night I made a few cuts with Lucas at 32:1. Mixed some up at 16:1 and tried it. No real tuning issues (1/16 turn on h and l). No smoke, or noticable difference in cut times.
My stihl ts400 concrete saw had about 10 tanks of quicksilver full syn. 32:1 through it last week. No noticeable smell. Took the muffler off last night. Piston was wet with oil and had started washing 17 years worth of tcw3 carbon out of the exhaust port and top of piston. Muffler was brown and dry. Seems like good stuff

Have fun wasting your time.
 
Here is an interesting read about H1R. Starts on page 2. http://www.wdarc.org/articles_files/2 stroke Oil Test.pdf

I googled "does belray h1r affect combustion". It was the second link from the top. Im sure there is more out there also.

thanks for posting the link red fir!!!
by far the best oil type test results i've seen. i'm sure glad to see 100cc airplane engines in it. good start at compare'in plane motors to chainsaw motors.

however,in my case of selling husqvarna chainsaws for over 39+ years,i have a weekly discussion with angry customers about oil & today's gas , and even the oil HVA makes me sell.(if they mix it right & use premium gas) i'd love to know the engine temp of all the seized up CHAINSAW engines , that i have worked on. and i will forget the ones that had burned up guide bars with dull chains on them,as all of us good chainsaw nuts (mechanics) all ready know most of the time what "did'er-in"....

Makes me wonder what test you guys are looking at..
 
Redbull, did you read the material about the H1R in the link I post yesterday?
If so does that help explain how H1R affects combustion?

I just don't think all oil is formulated equally. There is no golden ratio to go by. Each oil and engine and application requires a different ratio. That is where I stand at the present time. And honestly that doesn't matter until I do my test.

Regarding this test/article - I would simply say the guy should of tried several ratios. Just because the bottle says whatever doesn't mean that is what is correct for his engine or application.

it comes down to...
1. if there is more oil in the bottle and it's being run to rich. I personally think you could cause these problems with any 2t oil if you run it rich enough.
2. if it doesn't combust properly...inhibits combustion.

those seem to be the two camps of thought on H1R.

The application and load set the ratio not the other way around. And oil that won't combust well at 32:1 isnt worth a ****. ESPECIALLY one like H1R which is formulated for mx bikes which are speced with a 32:1 ratio from the factory.

there ya go again. 2t Oil is 2t oil. it's all the same stuff.
