Cant wait to see the results ................
Let me know if you need someone to help take the chains off your hands when you are done.
I'm anxious to see the results as well. Yes, there are plenty of variables, but your tests have shown some consistent results. If you're crazy enough to do the tests, I'll enjoy the results

Belray should not be used at less than 32:1 in any engine under 125cc.

Me too.
I don't understand that. How is one ester based synthetic oil ok at <32:1 in a chainsaw and another not? Would be a great question for Belray. Anyone asked? I have not. Just thinking out loud.
Me 3, after you showed me that picture of the piston, in my 13 tank 661, that was only ran with Stihl Ultra @ 40:1 with 91 E free gasoline.
I am not going to use Ultra anymore.

As long as Randy does not mind,, here it is.
12 full tanks were ran threw the saw, and I dumped most the 13th one out before shipping. 40:1 Ultra, 91 E free gas.
I have little over 20 tanks on my 441, with Belray mixed at 32:1, looks nothing like that, not even close!!

I am getting sloppy with a lot more than my files in my old age .................
I talked to a dude on here who has been runnin 40:1 H1R i his ported 441c for years without issue and he runs his saw quite a bit..i just mixed 32:1 because thats what the bottle said..idk..this stuff confuses me.
I would love to see the piston cleaned up and then after another 12 tanks on H1-R.
