There is extensive discussion of the differences between Mobil 1 and
Delvac 1 on Internet forumns especially those devoted to diesel
automobile engines.
Here is one of Mobil's responses to the MB club:
"What's the difference in the additive package for Mobil 1 (CF rated)
and Delvac 1 (CG rated)? What practical effect does this have on oil
changed at 5 - 10K mile intervals in an automotive diesel engine?
Mobil's Response -
The latest API service categories are SJ for gasoline engines and CH-
4 for severe duty, four-stroke diesel engines. Mobil 1 meets API SJ
and CF. The API CF category, introduced in 1994, is applicable to
light duty, indirect injection diesel engines. Therefore, Mobil 1
will perform well in passenger car and light
duty truck diesel engines requiring a API CD or CF oil. The API CH-4
category is intended for modern, large displacement diesel engines
which generate much more soot by comparison. Both Mobil Delvac 1 and
Delvac 1300 Super meet API CH-4 and have outstanding soot handling
abilities."
o I guess its up to us to cehck our engines, what oil they call for
and decide. My Volvo TAMD41a's are currently using Mobil 1, but I
plan to cehck if I should swith to HD synthetic at the next change.
I have been advised by my mechanic not to switch back to conventional
oil now that the engine is on Mobil 1.
