What oil is best? and what ratio?

[Keith Gandy]

They still make it

Ya they make the HT250 but not the FS250 but heres a mint one I love

 

[Keith Gandy]

1st. But what about both?

!! 1st is Mobil 1 at 40to1 in my 064/66 and the second is Red Armor at 40to1 in my 346xp

Thank you Keith. That Mobil 1 looked like it is brownish.
The 2nd pic with RA oil, almost looked like a clear sheen on the piston.

Ya the Mobil one was brown like that on the piston, exhaust, plug too

I wouldn't have any reservation using either of them.

Yuck! If you hadn't said it was a Stihl I'd have thought it was a 90's Homelite!

I figured. It's some brand I've never heard of. I'll get the name when I get home.
At 35°, it leaves strings in excess of 5' long when you're done pouring. Thins out in a few minutes of run time

I used that canam (or whatever it's called) stuff they had. It was so thick when it got cold. I could of cut it with a scissors.

Had to thin it out some first.

Sounds like the same stuff. I didn't thin it yet, but 50/50 With fuel oil probably wouldn't hurt

35:1 at whatever name brand oil is available, knock on wood, so far the only saw we have had blow up is a poulan wild thing.

Trying out some amsoil saber lately, seems like good stuff so far. I've been running red armor, good oil... but it is pricey stuff. The amsoil smells good too.

I ran it for years. Have no problem with it and no failures in anything i ran it in.

I normally start at 3:1, a guy can always add more fuel oil.

Ran Schaeffer 9000 full synthetic on a new 661. 32:1 for 12 tanks running 36"-41" .404

This is NOT the tcw3 7000 semi syn.

jug pics...

Looks real good Julian. Plenty of oil where needed. [emoji106]

 

[porsche965]

What would happen if you brought it up to 40:1?

I don't know. I will repeat something that @tree monkey Scott has told me a few times.

He doesn't run 32:1 so much for the film of oil between the piston and jug. He says you really don't need that much. He runs 32:1 because of the bearings. Those are what need the most oil.

No truer words have ever been spoken

 

[porsche965]

I do know that running more lubrication to a bearing than what is needed raises the temperature of a bearing. Does this matter in a chainsaw? Don't know. This from the research department of Timken Bearings, Canton, Ohio. Just curious. You have a great track record of successes I sure won't dismiss.

 

[porsche965]

We should take a poll on bearing failures documented due to lack of oil and the ratio of oil the bearings were run at. It would support your thesis.
Is this why Husqvarna is beefing up their bottom end of the new 572xp so they can still comply with the EPA @ 50:1 without further failures?
