The Mobil 1 synthetic turbo diesel truck and the Mobil synthetic heavy duty diesel 5-40w (Delvac 1) are the exact same oil just different packages.
The Shell Rotella synthetic 5W-40 isn't quite as good but it is FAR BETTER than any dino oil and costs less than the Mobil synthetics.
I use synthetic year around for less wear on the engine and less frequent oil changes.
