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

[Moparmyway]

2800 idle - 13100 top

Did some testing, after running hard, I let the saw idle for about 30 seconds to cool down, way I always do it. Pulled the muff. Would it look like that if I just shut the saw off? I don't know. The key is, I always pull the muff after cooling the saw the same way. To me that looks pretty damn good. Night and day difference vs lucas 32:1. H1r looked like that at 42:1 but it runs slow.

It definately makes a huge difference ! If you shut it off right away, it would get hotter inside and there wont be any oil on or in the muffler if you worked the saw good

Let a saw @ 32:1 idle and there will be spooge ........... run that saw good and it will be dry

To keep the mud daubers away, I go WOT then hit the kill switch when I am done running a 2 cycle. This coats a dry muffler real well

Which is why inspecting for residual oil and noting differance between different oils doesn't tell you much. The amount of residual oil is mostly a component of ratio and how the machine was operated before shutdown.

if the method for measurement is always the same, the results are consistent on the same products & ratios and there is a difference with other products. Then I think that is noteworthy.

I tend to agree. However, letting a saw idle for 30 seconds will lead to an oily appearance like pictured regardless of oil. There are some other variables at play also, such as how hot the saw got prior to idling down. I would think the hotter the saw was initially the dryer the appearance.
Honestly, I don't even worry about it as residual is mostly a factor of oil ratio and another good reason to run a little more oil than the factory reccomended 50:1.

Another factor I wouldn't worry to much about is cylinder temp. Other than to use it as a rough measure of increased HP.

Aspen Fuel in Europe is highly regarded as the premium pre-mix fuel. The oil is at 2% or 64:1. If it was available here I would try it.

One would think that there would be saws all over Europe blowing up because of the lack of oil in the fuel after reading this thread. ???

2% is a 50:1 ratio.

Btw a small piece of steel wool added to the muffler outlet keeps bugs and critters out pretty well.

I'm out of oil so now what do i buy?[emoji1]

There is a screen installed in there, you can see it if you zoom in

Whatever you preferr to smell.
Most all protect rather well at reasonable ratios.

I didn't notice it. And I don't run them, ever, hence the Stihl wool...pun intended.

Only Klotz and Stihl Ultra bother me. Klotz makes me nauseous and Ulta make my head pound.

Well then, next criteria for me would be cost .............. which smells best to you and is at the better cost per quantity

When milling or drilling odor is a nice thing not to have too much of,it messes with the sinus' for me ,the 2 oils i have found with least odor are the dumonde tech (very expensive) ,and the mobil (hard to get for most guys ),have not tried maxima yet or klotz ,anyone have any oils they have found that have little to no smell to them ? the H1r and the Yamalube both have a smell to them that when right under the exhaust messes with sinus'

K2 has no smell to me, it seems to be the best all around oil for me to use

Stay away from klotz if you dont like smells

2% is a 50:1 ratio.

Correct. I was thinking ounces. My mistake.

Wouldn't there be a chance of some of the steel wool dropping off into the muffler box? I guess it would just get blown out the port if it did.

I use the really coarse stuff, which isn't fuzzy and friable.
Btw AV gas as in 100LL is an alkalate fuel.

2r, mx2t and K2 have little smell when tuned properly.
I love the smell of Klotz Techniplate..

No MXT2 here, Trx250r180 is hoarding it all[emoji1]
