Marketing speak from oil companies isn't data..it's marketing speak..please do not post on this thread. I'm in the middle of email conversations with lucas, motul, and klotz. I will post them all up here when im done. I'm trying to keep all this data close together. please delete your posts. thx.
Your exhaust port roof shows a lot of buildup for so little run time and you are painting the inside of your muffler with unburnt oil. The area above the top ring shows a lot of buildup for such little run time as well. Should look just like the piston pic I posted if you ever run it enough.this 661 was broken in and run on h1r. 42:1 This is approx 9-10 tanks.
exhaust port - slight brownish but still transparent discoloration
top of piston - very very thin layer...hard to see exactly. There is a difference where the transfers are
my only concern is the area just above the top ring (between piston top and top ring) - some brown.
EXACTLY! That's why I suggested locking the other thread, not deleting it. Most all of the discussion was futile, if not actually misleading, until additional oils were tested. I fully support the end goal here.Keep in mind this is an open forum and if you wanted to keep unwanted post out you should have waited to publish the thread. They are not obligate to delete their posts but you can ask.
I think it would work fine. Of course if you had a dyno it would be the same concept.Is there another way to load the saw for testing without having to buy 20 rolls of chain ? Like rigging a saw to a boat prop in water ,water being the load off the prop ? seems like it would be more consistant ,and a longer load to get deposits to show up like a long cut milling would do ? Or would this not work ?

Wouldn't tell you much in regards to how the oil would perform in anything other than that specific application.You could connect to an airplane propeller! And run it at 6000 RPM for three hours!
