From a specialty list (Bob the Oil Guy).
The present formulation of Truck and SUV has been discontinued, effective this month. It is to be replaced by a new Truck and SUV that will be 5w-30 and primarily for gasoline engines, and a new product, "Turbo Diesel Truck" that will be 5w-40 and CI-4+ rated.
No clue about availability and prices of these new Mobil 1 products. Marshall -- Marshall Booth (who doesn't respond to unsigned questions) "der Dieseling Doktor" [EMAIL PROTECTED] '87 300TD 182Kmi, '84 190D 2.2 229Kmi, '85 190D 2.0 161Kmi, '87 190D 2.5 turbo 237kmi
