Definitely going to change the oil, I do it yearly as I only run this truck in the winter. The second time I started it the oil pressure message went away and it is registering 40# at idle, so looking OK. Thanks for the responses!
Hello everyone,
I have a 2001 2500HD Plow Truck that I just started for the first time in at least a few months, weather is cold here. Oil pressure warning came on. I know about the screen and the pickup tube, I am wondering if I can test the oil pressure with a manual gauge (or a scan tool, I have torque and blue driver) to rule out the sending unit. Appreciate any input
Thanks!
