I have friends that work in the Mobil bottling plant in Beaumont Tx. I had heard that the new Mobil 1 truck and suv was simply Delvac 1 rebranded. Both friends have confirmed this to be true, Delvac 1 and the truck and suv oil are bottled from the same tank. Both of my friends says it is common for Mobil to rebrand an existing product. I hope this helps people who want to use Delvac 1 but have diffuculty finding it.
