So I spent a little time talking to an oil chemist this morning and decided to try something.
Here is JC blend #8
368 lbs load + at friction spike
2.46 heat from high pressure shear
.023 heat from friction
I ran this test until the arbor motor shut down due to overheat.
The follower pressure was over 500 lbs. and follower temp was 430 degrees.
THE FOLLOWER DID NOT SCAR, even though the arbor was blue from heat.
So what is it? It is the same oil that was in the cup last night.
Bel Ray EXP 20W50.[used]
I just dumped out 20% and topped it back up with Royal purple XPR 20W50...
