Why are diesels so noisy when cold?
I know this is probably a dumb question for all you guys that have had diesels for years, but this is my first winter with one.
I was just curious why they're so noisy and rough running when cold.
Should I go to a different grade oil? I just changed it with 15/40 2k ago, so I'd hate to waste 40 bucks worth of oil if I don't need to. It runs in the 20s most of the time where I live in the winter with occasional dips to single digits.
