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

[KG441c]

288 is 54mm. All the aftermarket are 54mm.

Mike have u used one of the 54 big bores on a 181 se?

Sometimes overthinking is needed

i need to buy both of these for a 32:1 test

H1r works great for drill bit lube.

I'd use it for keeping dust down on a gravel driveway...

 

[KenJax Tree]

Not sure why you're so hung up on solvents. I've never had a problem running 40:1 using any oil i've used. Commercially not testing cookie cuts.

 

[KenJax Tree]

Ok gotcha[emoji6]

Nothing wrong with Randy's port work.

Nothing wrong with H1-R either. From what I can tell it's one of the best oils out there. You guys just aren't thinking about it correctly...


Stihl ultra = di-ester oil (~80-90%) + additives (10-20%). That's it. NO solvents in it.

Additives = are your rust inhibitors, cleansers few other things


H1R = di-ester oil 90% + 10% additives. That's it. NO solvents in it.

Yamalube 2r https://www.jakewilson.com/docs/MSDS_Yamaha_Yamalube 2R.pdf
blue dye .5%
base oil (dino and syn) 54-75%
solvent 10-15%
Pour depressant - .5%
additives 16-20%


There is less amount of oil in the bottle of yamalube.

News flash: blue dye, pour depressant, and solvent. ISNT ****ING OIL!!!!!!!! (tried to explain it before, but no one would listen, just wanted to say I was stupid, crazy, wacked etc about my challenge)


If you run 32:1 yamalube, then you are running leaner then 32:1 belray h1r.


If you discount the %'s of solvents and non oils in the yamalube bottle. I'd guess you'd have to run around 25:1 yamalube to get the same amount of oil in the gas, as you have with 32:1 H1R

run 25:1 yamalube probably see some performance issues... ie. THAT MUCH OIL IN THE MIX might hinder combustion, cause piston to slow down, might cause "tuning oddities".


And no I'm not saying you should all run 50:1 H1R.

Seems to me the thicker oils like h1r 800 r50 should be run 36-40:1.

Thinner oils 2r, k2, 710, lucas, should be run at 32:1. Me I wouldn't go even to 40:1 on those. Since your really running leaner with most of them...all those mentioned have solvents which isn't oil.

as for what is cheapest vs running a thicker at 40:1 vs a thinner at 32:1. bean counters can figure that out.

Yamalube will run cleanly down to 20:1 in my expiereance and kart guys run it at 16:1.
Most oils do not inhibit conbustion like H1R does and besides its just dirty burning crap.

H1R is just dirty burning crap.

And I might add that just about every actual FD certified oil has a solvent in it and for good reason.

 

[bwalker]

H1R burns clean for me. You run enough of any oil and it's going to burn dirty.

Yamalube has a lot of non oils in it....so many I bet it would run 25:1 in a saw no problem.

Lot of non oils? It has around 10% dilluent.. big deal..
I know your hung up on H1R, but I would suggest just about any other oil talked about here is a better choice..

 

[bwalker]

not buying the whole certified oil thing. sorry. stihl ultra is certified and it's dirty as crap. I've ran it in my saws for years at 40:1 , 45:1 and 50:1. DIRTY no matter what. Have heard from several people it's even worse at 32:1.

Others haven't noticed Ultra to be dirty. In regards to that piston pic you posted you ran very little of it and jumped to conclusions. The rust preventative that's sometimes added to motors at the factory could of caused that, or more likely you were running on the lean side.
I also do not believe that Ultra is FD or EGD certified. It only claims to meet FD. Say what you want but the most current ISO AND JASO tests are pretty damn stringent.

run 25:1 yamalube probably see some performance issues... ie. THAT MUCH OIL IN THE MIX might hinder combustion, cause piston to slow down, might cause "tuning oddities".

Which is it? You're contradicting yourself.

stihl ultra is certified and it's dirty as crap. I've ran it in my saws for years at 40:1 , 45:1 and 50:1. DIRTY no matter what. Have heard from several people it's even worse at 32:1.

Like I said before, that's not always the case. I have a customer that runs it at 32:1 with VERY clean results. You can't ignore the data that doesn't match your preconceived ideas. You're still jumping to conclusion without supporting evidence and contrary to what others are trying to tell you.

 

[bwalker]

Btw the JASO smoke test is ran at a 10:1 ratio and the exhaust port blocking test is ran at IIRC 5:1.

 

[bwalker]

what part of what I said, didn't you read? let me help you: "I've run stihl ultra for years in my saws at 40:1, 45:1, 50:1..."

we all know you've got it all figured out. But if your going to respond at least read the post completely or slower or whatever it takes.


I don't care if it's certified or not. I'm going to test it and if my tests show 2r rocks, then your going to say I told ya so. And if my tests show it actually sucks. Then your going to say im an idiot or I did it wrong or whatever...no matter what you will think 2r is the best. Great.

Frankly, I don't think you have the knowledge, objectivity of the credibility to make any judgment on oil performance. Your more concerned with being right than getting it right.
It's not just what I think in regards to 2R. It has a 30 year track record of excellant performance in a variety of applications. There are also other oils that might be better, but you won't find very many and none with as long a record.

 

[bwalker]

FWIW I ran ultra briefly and didn't notice it to be dirty, but really I can't say for certain as I didn't run it long enough.

 

[bwalker]

contradicting myself - taking things out of context again aye brad? That is what your going to try and discredit me with? Pretty weak. I expected more out of you.

yamalube at 25:1 performance wise yeah might suffer vs 32:1. Might see some "tuning oddities". BUT it has so much non oil in it that it might still run ok at 25:1.

Clear enough for ya now?

Your grasping.. I have ran it lower than 24:1 and didn't have any issues. Expiereance trumps guessing.
And you are really being a drama queen on the solvent thing. 10% isn't much, but if your hung up on it use R50 or better yet 800T...anything is better than that tar you are running.

 

[bwalker]

Brad, I see you can still by Mobil 2R on ebay shipped from the UK. That's the ultimate!

Its not cheap either

I have a quart on the way from Germany

No. I don't see where I took it out of context.

Do you not see that you're making a lot of assumptions without sufficient evidence, or contrary to what others are telling you?

You've provided a lot of useful information in this thread. I just think you're making assumptions that you don't know to be true.
