I normally use an AGIP synthetic for my 86 300SDL, recommended
by my MB mechanic. The winters are just too cold here in the
northeast (Vermont) to use conventional in a diesel. I just moved to
the boonies, and the only synthetic I can get around here
is Castoil syntec 5W-50, or Mobil 1 10W-30 or 5W-30. Would
either of these be OK for a diesel in very cold weather? Thanks,
Jim

Mobil 1 5-40 (also known as Truck/SUV oil). According to many diesel
experts from another news site, it is same as Delvac-1. I have been
running my 85 300SD on this oil for over a year now. Had no problems
last winter here in NJ.

There are two aspects to lube oil: its SAE weight and its Service Category.
You need to use diesel service category oil, not below 10 SAE weight,
see the API chart.

have used Mobile 1 in my '91 SDL since I acquired it in '94. Never any
problems, 'course I'm in the south!

Also a Vermonter here, in southern Windsor County, 2300 feet above sea
level.
Use Mobil 1 Truck and SUV 5w-40. It is CI-4 rated, and available at
WalMart for about $20 per 5 quart jug.
Most of those automotive synthetics are not CI-4 rated, so you might
as well get something better for essentially the same price.
