I'm an owner/ operator in Idaho with US authority. I have recently purchased a 2019 KW with an X15 cm2350 CPL 4343 with 718k miles. It was owned by a husband/ wife team running coast to coast produce. I got a load of semi trailers from Pennsylvania to WA for my first trip back home. I'm grossing around 55-60k lbs. I looked through 70 pages of your website threads yesterday trying to find info on consistently high oil temps. This engine is factory. Currently running oil temps between 240-250+ and averaging 4.5 mpg on the trip. Boost gauge is reading 28psi in hard pull. I am completely new to tier 4 engines but I'm trying to keep up with the changing industry. If you've got the time for a phone call or further email correspondence, I would greatly appreciate it. Engine spec printout does 565hp and 1850lb/ft. Thanks!
