I wonder how many bearing failures at 50:1, likely not many
661 Oil Test 32:1 vs 40:1 vs 50:1 ?

Ive seen one on a ms261 when I got it but dont have a clue what oil or ratio was ran before I got the saw
I wonder what it would look like if you ha mixed it to the "proper" ratio of 42:1 or even 50:1..?...
Post up a pic of a saw run hard for 12 tanks with Ultra and you see burned pepperoni pizza.(Second pic)
Fuel quality and run conditions play a real large part in how each users experience with any particular oil is
An idled saw will spit out oil @ 32:1
A saw run hard will be dry @ 32:1
I bet the outcome would be different, in a good way.

Also saw another on a husky 262xp that had been ran at 50to1 with Stihl orange bottle and silver bottle

What year would the 262xp have been made? Any idea of hours on the unit? I heard they are good saws.

Does anyone know if bearings give any kind of warnings in chainsaws before they fail? Vibrations? Drop in power? Noise?
Are bearing failures always catastrophic? Meaning taking out the whole top end.

You gotta consider that AS is .0000000000001% of the users out there and how many people just use 87 octane E10 that is a year old and whatever oil they can find.

1991 on the one I owned. Excellent saw. Crisp throttle

I bet a different fuel (like VP SEF) at the same ratio would have looked much better as wellI wonder what it would look like if you ha mixed it to the "proper" ratio of 42:1 or even 50:1..?

How do you know what affects those "non-oil" components have on the over all lubricating qualities of any given oil?
Interesting info in this thread.
bwalker, maybe I missed it, but what is your preferred oil for a woods ported chainsaw.
I know this is an oil thread but how the does the fuel selection factor into all of this. I always assumed, fuel choice mostly affects performance and oil choice mostly affects lube/protection. Sounds like they both affect each other but to a lesser extent.
Going with my long standing practice of assuming the opposite of what the EPA says is good for my saw, is actually good for my saw, I run 32:1 mix.

Unless you're getting some exotic fuel, it has very little affect on performance. I have tested and documented that myself.
Interesting. I tried switching from canned fuel to ethanol free pump gas and there was a noticeable difference in saw behavior. Not sure how it affected performance but it ran rougher warming up and required some carb adjusting.
Going to try this for a while instead of canned Trufuel. Almost out of H1R so trying to decided on a oil to try next

Canned and E-free fuel will require leaner jetting, but will have little affect on power. The same holds true for most race gas.

My ported 660 using 800 off-road (with Sunoco 110 octane) hasn't shown any deposits or builldup at 32:1. I've only used about two liters but that should be a representative amount to draw a conclusion. Not sure if I've already posted this one.
The same performance tests need to be done with some of these other oils in order to draw any conclusions. The only thing that has really been proven so far is that one oil makes more power with less oil, particularly in one model saw. That's not near enough data to draw any kind of conclusions from. Good stuff here, just not near enough yet.

None of this will ever be drawn to any kind of conclusion other than different opinions and assumptions. There are just way to many variables.
When you're done with all that, the only thing we really have is performance indicators. We've still yet to test cleanliness and protection.
Cleanliness is problematic because it will vary GREATLY based on how the saw is used, how it's tuned, if it's ported, and the kind of fuel used.
I'm not sure how to best test the protection factor. I think most all of us would agree that most ANY oil will provide a very long life, probably even at 50:1, and for sure at 32:1. Therefore, I believe the best way to test that is through some kind of torture testing.
Stayed up late last night trying to get through this thread, then IT WOULD NOT LET ME POST, THE SITE WAS DOWN AGAIN!
Ron, nice knife, I thought that is what it was, my Uncle always used to carry a Randall.
After reading everything in this thread, I'm sticking with 93 octane and Saber at 40:1. I see no reason to change.
Regarding oil protection, I think scoring the cylinder is a more likely concern than bearing failure. That is why I choose high test, it is supposed to run cooler.

On most saws, yes. I wouldn't take my chances on a ported 372 or 390.
