STLE Presentation Paper
Interesting testing, with GMO (Glycerol Monooleate), MoDTC, and a "secret" experimental organic friction modifier, on a friction testing machine.
Establish the tribofilm, and the friction reduction associated with it, heat soak and monitor.
Change oil to no FM additive, and test.
Change back to FM oil, and retest.
Quite some mnay moons ago, I had dinner with a chemist who was working on Magnatec (Castrol Start-up), and he claimed that their ester gave improved friction when the reference oil (and the between test flushing oil) was used between Magnatec runs.
Guess the experimental FM indicates that it's certainly possible that an additive can survive an OCI...and MoDTC at the temperatures and times tested didn't fare so well.
