This will be my first winter with MB Diesels (84-300D and 81-300SD). I am in the Raleigh, NC area. What things do I need to attend to? It does not get consistently below freezing, but I want to get the best from my engines.

Let me know the best attack. I am using Rotella 15-30 in both and I have changed both fuel filters (on both). I am trying to get some MB antifreeze to top off the radiators.

Thanks, as always.

Don
