Any contributions we can use?

Why would anyone bother at this point. The most valuable information was in the first few pages.

Boys I'm done! The overall atmosphere here on AS and other saw sites, as well as the quality of discussions is in the garbage, and has been for sometime now. The people in many cases are honestly not much better IMHO. At this point it's not worth argue or getting into it with people who have nothing better to do, and are obviously not worth one ounce of my time.

The day of exchanging real and valuable information is long gone, it's all about self promotion and bull headed egomaniacs.

Have fun boys.

I look forward to seeing this 088 after you have a few dozen tanks through it ............. specifically, I would love to see pictures of inside the muffler looking at the ring lands and piston skirt through the exhaust port

boat oil 32:1 aka schaeffers 7000 tcw3

this 661 has only been run on schaeffers 32:1 ...so this is after the first 6 tanks.

Have any other pictures ?

Check this out and really digest what it's saying.

As I have heard you say many times before however this is coming from an oil manufacturer and their sales propaganda. I would like to know how they measure such precise % numbers of oil left in an engine? How do you harvest the oil and what measuring option are they using to come up with these %? I see that they say "approximately" leaving themselves an out from the absolute.

Often time when you see % in a report it makes it more believable or when you post tenths of a percent most people draw the conclusion that their work is done with exact precision.

It was an in depth study they did. The pdf I posted was just a quick and dirty as I no longer have the full right up. The test was ran using radioactive isotopes. Not sure how the residual measurements were taken.
Irregardless the key point isn't what's left behind its how fast the oil moved through. If one wants their saw full of oil just idle it for a few minutes prior to shutdown.

And this wasn't bs marketing either as they never mentioned specific oils.

Pulled down my new ms 260 to do a base gasket delete and this what it looked like. Motul 800 and premium ethanol free fuel.[/ATTACH] View attachment 451331
crikey! with a piston top like that and you reckon stihl ultra is dirty, should have gone to specsavers! LOL i notice its that thick that its starting to peel off, might need a screen with bigger gaps for them to escape!

Usually I see those flakes in the center of a piston that was ran hard for a short time and idled for longer periods.
The idling builds up some crud, the hard running starts the flaking, but not enough hard run time to remove all the flaking

I've heard over and over again Ben that you have said it takes many many tanks of running to get an internal read on an oil/mix or when some sort of porting, even exhaust is made.
What type of time do you have on this 260 without any changes made whatsoever to this saw?

The carbon on the piston imo is normal and the saw has nice transfer wash also. I wouldnt care for the buildup starting in the exhaust though. Ben what did the ring lands look like?
