Synthetic engine oil was covered in detail in
the last issue of Star Tuned, so we will only
touch on it briefly in this article. For vehicles
with the Flexible Service System (FSS), only
synthetic oil should be used in all V-6, V-8 and
V-12 gasoline engines. Conventional mineralbased
oils do not meet the performance
requirements for an FSS engine's extended
drain intervals.

For Mercedes-Benz vehicles prior to MY 1998,
petroleum-based oils may be used. Synthetics
can also be used in the older vehicles if the
engine is mechanically sound and there are no
oil leaks. Any leak must be fixed before changing
from petroleum-based oil to a synthetic
because the more “slippery” synthetic will
make the leak much worse.
I do not see anywhere where Mobil Delvac Diesel is Approved.
Take it for what it's worth. But if it's an Official MB Stealership,
I would be taken aback if they were using Non Approved Parts,
Fluids, etc.
If I was in your same shoes, I would say NO and tell the Stealership Manager
I don't approve of those sly tactics. But that's just me.
If I am paying top dollar, I want top dollar advice and repairs.
If I am doing this at home ( which I do ) It's up to me.
My call, all the time.
For my money, Approved High Quality Synthetic Oils ONLY.
I went to the dealership today and they recommended Mobil 1 Delvac 15w40 1300 Super. I'm hesitant because I noticed on the box that it says it's for DIESEL ENGINES and it has a picture of a semi truck on the bottles, lol.. Will this be ok with my car? Thanks.
