Most recent towing trip yesterday. The coolant stayed nice and cool, about 195F average while maintaining 63 mph. The oil temps climbed slower than before, but still reached 224F peak.
I'm very happy with the coolant which is obviously much cooler, but the oil is still strangely high for my taste.
How is it possible there can be such a gap between coolant temps and oil temps? I feel that coolant dropped quite a bit but oil barely runs any cooler relative to the drop in coolant, so what is happening; why is the system not removing more heat from the oil?
Maybe, in addition to the oil filter relocation you could add an additional oil cooler and maybe that'll get you to the lower oil temps that you seek, especially when towing during the summer months.
I've also done the simple AGS delete and that has helped tremendously with reducing the coolent/oil temps. I may swap out the oem t-stat to the 180°. I've also changed out the oem transmission heater t-stat with @caulk4's transmission t-stat bypass valve reducing the temp ~40°.
I reside in Louisiana where the summertime heat may be one thing, but adding the humidity makes things worse for my HEMI.
Imo, the folks in control should stay out of the automobile business and focus more on "fixing" other things ...
Keep on hammering down and good luck.
