Hi All,
New to RAM and Cummins all my last trucks were Duramax equipped so this may sound silly, sorry.
2019 2500 6.7L Cummins, 68RFE, with 5600 miles on it. It has been to the dealer for the trans plate recall and flash updates, so those are done. I finally got to tow with it for the first time a decent weight behind it yesterday (scaled 9100 lbs). About a 8 hour 400 mile trip. 88 degree humid weather, hilly terrain, cruise set at 67 mph, tow haul, full exhaust brake, with the AC on.
Truck did great but I noticed something odd (at least to me) with the oil temps, I use the gauge summary view on the center cluster. Coolant temp sat in the upper 190s-205ish, trans temp stayed right at 168 and never moved, oil pressure 47-50psi. However the oil temps would slowly steadily climb (unless going up a grade then they would climb a little faster) to the 203-207 mark and then plummet quickly (like approx 2 secs) down to about the 172-174 mark. Then take 15-20 minutes or so to slowly climb back up and rinse and repeat. Is that normal? Seemed odd to me. It did it countless times on the trip. Seemed to run fine no issues, truck pulled well. I don't believe it was during a regen I checked for that a couple times. I'm happy; I've just never seen that with a oil temp before.
Thanks!
