Low oil pressure?

J.rob, wouldn’t highway speed cause lower oil temps? It doesn’t take much power at all to cruise the highway with all that nice cool air to flow through the engine bay, across the oil pan, where oil gets cooled the most.

idling at a stoplight would heat the oil up much much faster.

Much/most of the heat in the oil comes from the heat in the pistons, which goes up with the power being generated, even at cruise.

I was watching my oil temp gauge on the CTD towing a 20' trailer in I-64 through the mtns of WV last week. Going up the mtns, the oil temp would rise to the 220*. As soon as I started downhill, the oil temps would drop like a rock; they would drop 50-60 degrees with a 45 second steep downhill run. That change is overly extreme versus our typical small blocks, what with the biiig oil cooler (plus a big turbo with oil flow in it) in that truck but it illustrated the correlation of oil temps with combustion power.
