And I just looked at that thread... for starters the first thing I noted was the incorrect attribution of flashpoint to how an oil behaves inside an engine.
Flash point is listed on an MSDS for storage and shipping purposes. It only tells one 2 things. 1. If the oil has a diluent or not and 2...
His test where not tests and he doesnt have any idea how or if Super M caused the failure or the heat or if there was any dufferance in heat. His methods are twrribke and a hand held twmp gun are highly inaccurate. I use expensive Fluke temp guns and even those have a huge margin or error.

We ran one a bulk tank with 50:1 mix. The injected models got 50:1 and oil injection.
We ran all tge camps for cycle stuff on the same mixed fuel too.
