Hey Paulk1, I am not too sure, your best bet would be to call the dealership and find out what they use on diesel engines. But as it looks you are still under warranty so in my opinion I would just let them change it.

If it is the same then you can use the same oil, but if it's different send them over an email. They are usually very good with getting back to you.
