Improper ignition timing or a slipping V-belt also cause too high oil temperatures
I'm wondering where everyone else is coming up with their figure for too high oil temps.

Fascinating that my '74 manual has the exact same wording in it (page 16), except that it specifies 285 degrees F. Maybe as the engines ran hotter for emission reasons, they upped the temp recommendation. And, my manual pictures an 11 blade fan, not the dreaded five.
