[W126 Coupe] oil additives

"But what shall I use for my Mercedes 300 SD diesel"

Mobil 1 make a synthetic diesel oil called Mobil Delvac 1 5W-40  and then 
there is  shell rotella synthetic.

In my diesel excursion  I run the standard diesel rotella oil in it 15w-40. 
But I do use the Mobil 1 Filter which is a screw on. They don't make a 
canister filter like MB uses.  The only place I found that sells synthetic 
diesel oil is wal-mart and it the rotella brand.  If your looking for M1 
you'll have to order it on the net.  And its expensive either one!  Plus I 
don't like the fact that they synthetic is rated at 5W.  Truck or car diesel 
need 15W.
Personally I tried M1 standard diesel oil, delvac 1300 and did not care for 
it. I went back to rotella truck runs better with rotella.  I cant justify 
the synthetic oil price for diesel oil when Ill get 500,000 miles on the 
motor anyway !  Just my 2 cents :) Plus the big rigs all use rotella.
