General Questions for Cummins X15

[RByrd]

Thanks for the info. While I have you, I just made my first run today with a stacked heavy haul trailer. I am grossing 88,000 lbs. My oil temp stayed around 225 degrees. Is that normal? Also, while running down the road, the truck maintained 38-40 lbs of oil pressure, but when I stopped after 360 miles and was doing my cool down, at 900 rpm the oil pressure dropped to 20 psi then when I low idled for a few minutes at 650 rpm, it dropped to 15 lbs of oil pressure. That seemed very low to me but I’m not familiar with these engines. The truck has less than 500 miles on it. It’s the 565/2050 X15 with 4.30 rear ends. Thanks again
