With the Low Sulfer diesel, Id recomend running some type of additive for extra lubricity. I use Power Service, either in the white or gray bottle. Others use Howes or Stanadyne. They all do the same basic thing. Some people feel they arent really needed, but can the added lubricity really hurt? No. With ULSD (Ultra Low Sulfer Diesel) I dont want to be the one to find out that its not what diesel used to be.
I also changed my engine oil and filter at 1,500 miles just to get rid of anything the factory may have left behind just to be safe. Then I use 4-5k miles as an oil change interval. Book says 15k, but I just cant let myself go that long... I change my fuel filter every 5-7k miles or every other oil change with the newer 7 micron filter not the 10 micron. Thats pretty much what you need to know for now.
Of course this is what *I* do. Everyone has their own ways of doing things and have their own trusted brands of oils and filters. So that part is up to you. Dont be afraid to ask questions, this is a great place to learn how to take good care of your CTD. Enjoy! :-laf
