    6 quarts with filter. i run 10w30 year round granted my truck are in the heated garage overnight so they are 70 degrees when started. if your truck sits out over night i would go with 5w30.

    Haha, I just changed mine. 6 quarts of 5w30 and an AC Delco PF46 filter. I put pennzoil high mileage in mine since it has almost 130k on it. I run either Kendall, Mobil 1 or Pennzoil. Do not use 10w30 in the 6.0 That engine absolutley hates it and runs the gas mileage down. I know from experience :D

    You could use 10w30 if it have lot miles or worn out.

    But better is 5w30 and see if it not burn oil.

    I am sure mobil 1 oil is good for this one since I have change oil on Cadillac CTS require mobil 1 5w30 it say on oil cap.

    6 quarts, we use 10w30 year round. If they were my trucks I would use 5w30 in the winter.

    Thanks guys. 5W30 it will be. It's in an uheated garage/barn or outside all the time, so I'll run the 5w30.
