Mobil 1 5w-40 Turbodiesel is no longer the same as Delvac 1. It used to be the same when it was called Mobil 1 5W-40 "Truck and SUV." I believe they both have the same CJ4 rating, but the additives are different. Delvac 1 is the same formula as the old 5W-40.

It doesn't magically cost less than the new stuff, it's different!
