Do you track it?
@YogiTheCat and I recently had a nice exchange about oil temperature, as it is one of his concerns in choosing an appropriate viscosity. He asked me at the time what my oil temp was when towing and I told him I hadn't really checked, but I expected it was pretty close to normal, given my wife's truck has a pretty substantial oil cooler.
Today I towed the Supra back from the cottage so it was a good time to monitor that. It didn't go above 106C (223F) the entire trip, despite a few WOT runs, some bumper-to-bumper due to an accident...etc.
In tracking the Jeep for the last week, which also has a rather massive heat exchanger, it sits at 106C too, so I'm guessing that's the temp FCA targets.
His truck doesn't have an oil cooler, so he sees a rather broad range of oil temperatures. Given how many trucks "back in the day" didn't have oil coolers either (my old F-250 sure didn't) I'm guessing this is only becoming a worry now as thinner oils, like 5w-20 and 0w-20, probably soon 0w-16 are spec'd for these applications. Viscosity control through temperature then becomes a potential concern.
