I've been using Mobil 1 Turbo Diesel Truck 5w-40 for a while now. It meets the CJ-4 and CK-4.

After doing some research. Think I'm going to go with Mobil Delvac 1 ESP 5w-40. It's low ash.

Why the switch ? I'm on tdt now.

I've had good reports with TDT. I want to try the ESP because it's a low ash oil. And see if it changes my regens.

Did oil change today. I changed from Mobil 1 Turbo Diesel Truck 5w40 to Mobil 1 Delvac ESP 5w40. Supposed to be low ash. See what this does in the next 5,000 miles.
