We have stuck oil type and overheating being related together also on some race cars.
One car we were involved with was running on a new type of oil and overheated in 10 mins of qualifying.
An oil change later and it completed the 3 hour enduro later that day with no problems.
We found the the car had a large oil cooler fitted,
but the new type of 'better' oil did not absorb heat from the engine as well as one of it's "benefits'.
This meant the heat not absorbed by the oil and lost by the oil cooler now also has to be lost through the radiator which was just too much for it.
Other simple fixes could be a change of fuel, as have found the 98 creates more heat than avgas,
and of course E85 is a geat cooler, but E85 requires more than just a drain and refill of the gas tank, there is a lot of other stuff to look at too.
