How High for Synthetic?
I run Mobil 1 Turbo Diesel 5w-40 (full syn). How hot can it get before it compromises the oil?
Here is the long version, again-
Delta temp 2-3 degrees when I first installed the DashDaq 2 years ago
delta temp around 20deg, oil cooler replaced 8k miles ago at dealer
deltas after change were about 8-10
deltas gradually 20-30, 40-50 with 5th wheel (4 weeks ago)
flush with RESTORE and RESTORE PLUS,
change thermostats for good measure
temps 192-202ish, but spiked up to 215 once for no reason. Heat seems to take a while to get hot, but when it does its all at once.
filter kit arrived today...
probably asking dealer to order a new oil cooler tomorrow, will return to stock over the weekend to get the wrench light.
However, we have a camping trip planned next weekend. Truck might not be fixed. Just put 130 dollars worth of oil in it and don't want to ruin it.
Anyone think I have a bubble?
PS, I have about had it with this situation.
