I have a Dodge truck with the Cummins diesel. I have been using Traveler 15-40 oil that I buy at the local TSC store. I have recently switched to Shell Rotella 15-40.
I have thought about using this in some of our cars, but I have read that the "diesel" oil has too much detergent in it for a gas engine.
In a lot of the post on this form it seems that people are using the 15-40 oil in their gas engines, so I guess it must be OK ??
