3.0 duramax observation

[Paulie-G]

I have a 2006 LBZ that I use for towing.
when climbing 4 to 6 % grades towing a 18k (conservative #) the engine oil temp never exceeds 235 degrees.
I just installed the Banks gauge setup and I'm shocked at how hot the ZR2 gets. Engine oil. Cooling system ect.
Emissions related I'm sure. Anybody installed an aftermarket engine oil cooler.

Well why leave us hanging, how hot is it getting?
