Rusty, Paul Lamar conducted a oil burning test to see how much “sludge” is left after burning out.
Turned out 2 cycle oil was the best MMO was not that good for this application.

His test was 'interesting', but if Tracy, Ed, & probably others are getting unburned 2stroke oil scavenged from the combustion chamber into their crankcases, I gotta ask if his test has any significance in this application.

What do you guys that are flying think?

You're right Charlie.
1) Using Mobil 1 synthetic you can actually see the red-tinting from the scavenged MMO after a while.
2) The belly of the airplace is tinted redish after a while (of no cleaning).
Both are indicators that at least the MMO is not being burned. Don't know if not enough time in contact with combustion gasses or why.
