Re: Where do you get 20W-40 oil???
I also use mobil 1. Could only get 10w 30. From my dealer. Goes against the manual, as you have demonstrated oil is a confusing business.

Hey Steve,Mobil 1 Turbo Diesel Truck 5W-40
Mobil 1 Extended Performance 15W-50
I use these two oils. If you use the search function you will find a huge amount of links explaining why people use different oils.
