Purchased 05 Dakota, 4.7. Manual says 6.0 quarts with filter. Day after new checked oil level and showed more than 1/2 quart low. Guessed it was oversight at factory. Replaced oil at 1k with new filter and 6qts. Same thing, showing more than 1/2 quart low. Stealership says they always add about a 1/2 qt more (6+1/2) for the 4.7. Chry headquarters tells me capacity is 6 qt not 6 1/2. Anyone one with a like problem with 4.7. Checked TSB's and found nothing. Any help thanks.
