Yes, I could certainly be out of date, since I usually buy about 8 gallons
at a time, and that lasts a couple of years for me. Actually, I thought the
Truck&SUV Mobil1 had disappeared with their last change, since it
disappeared from local shelves. But I suspect that Delvac1 will be around a
bit longer, as real truckers don't seem to have such short attention spans
as car drivers seem to have - hence the maketeers at Exxon-Mobil with their
constantly changing numbers and bottle shapes and colors. Also, note that
the advertising says that the Truck&SUV is for gasoline engines, Diesels
don't seem to be included.
Anyway, I wouldn't want 5W-30 in my Diesel unless I lived somewhere North of
Calgary. I like the idea of 15W-40 standing up to the temperatures and
pressures on my engines!
Some of us old-timers remember the gas crunch days of the 70s, when the car
manufacturers figured out that by using thinner oils, they could save a few
horsepower, and hence improve mileage. I believe the trend to 0W and 5W
oils is rooted in this concept, which is a good idea as long as you get rid
of the car before it gets too many miles on it. The manufacturers have a
vested interest in getting people to buy new cars - not keep them for 20-30
years!
Using too "thin" and oil was a big part of the downfall of GM and their 5.7
V-8 Diesel - GM said to use straight 30W, and the gas stations put in
10W-40! It had to be better, because it cost more, right? WRONG!

You're out of date Werner. Mobil 1 Truck&SUV is now 5w30, been that way
for a year or two.
Turbo Diesel Truck is the 5w40

Anybody needing Mobil 1 should know that 15w50 is the next best. I've
found a good supply at the Wal-Mart in Rindge, NH. You want some drop me a
line and I'll give you a quote...
