Try doing a diesel flush if you have the extra oil to get any excess debris out of your engine. 4quarts of oil 2 quarts diesel Let run to operating temp
It only burned a quart of oil in 2000 miles so no need to go extreme. It's no worse than my 2011 Silverado was.
Normally it doesn't bother me if the pleats off on spacing but this one is the best I have ever seen.
