Brad, I've never run 32:1. but have been running the AMSOIL at 40:1 in all my saws w/o any problems.
EXCEPT: I had to do the reset procedure when I got the saw back from Randy. Pretty sure he was running 32:1 in them at the time.
Wow, I have never seen a builder recommend 50:1!!!
The info I got from this site said the AMSOIL Saber provides more protection than the Stihl oil.
Well for better or for worse I have a liter of Motul on the way; and, a jug of Maxima as well
I got cross ways with the Amazon vendor because they tripled the shipping on my order without telling me
$16.00 to ship a $20.oo bottle of oil
I cancelled the Motul and ordered the Maxima and then the vendor e-mailed, explained that shipping to Alaska was always automatically increased to a set minimum and asked if I still wanted it if they shipped it at the origianlly quoted rate
I told them to go ahead
So now I have a couple oils inbound to play with
Like MustangMike I am currently running Saber at 40:1 in my two mostly stock saws
I have never pulled the top end off any of my saws but peeking into the ports things look ok
I just get a lot of smoke for the first minute or so and a LOT of soot as well as soggy mufflers
Both saws run a bit rich but clean up well in the cut on larger 12"-15" poplar rounds
Part of this hobby I love is the experimentation
Cheaper than being a gear head again and blowing up a V-8 when you goof
Best
Michael
