Just got back in from a 30 mile run to a car show. Tried an experiment as suggested by the Mobil 1 tech. Put some duct tape over the
oil cooler before starting up.
The
oil temp evenually rose to 190 F and stayed there. Seems to have done the trick. Byproduct is the
oil pressure was perhaps lower at idle, say 32.
Could be just my imagination, but she is idling smoother when warm.
Outside temp was about 78F when doing this test.
Cheers
