Sorry if this is a Repost.
I was fishing around the Mobil website and found some info on the TDT that has replaced 5W-40 T&S. As many of you may remember T&S was the same as D1 when introduced and then diverged. This is no longer the case as the following is a direct quote from Mobils website from the Myths Page following the Applications Chart.
Quote Mobil,"Mobil 1 Turbo Diesel Truck 5W-40 and Mobil Delvac 1 5W-40 are the same formulation and meet the exact same performance requirements."
