<FONT face="Comic Sans MS">I too had excessive oil consumption, 2 quarts in 600 miles @ 1,400 miles. While Dodge ultimately was willing to pull the valve covers to check for missing valve stem seals, I figured I'd seriously document the usage before opening up the motor. I did this by first changing the oil and filling it exactly to the fill mark, running the the engine a bit and the next morning topped it off again. Then I used a dial caliper to measure the drop over time. I always measure the morning after use, so any thermal or oil cooler drainage variances were eliminated. I logged this in an Excel spreadsheet and used a factor of 0.332 inch = 1 quart of usage.
In my case, the consumption improved from a measured 1 quart per 800 miles @ 2,500 miles to a current 1 quart per 3,000 miles @ 4,700 miles. Wasn't a straight linear improvement, but by averaging 14 data points I feel pretty good that it was a break-in issue for me rather than a mechanical problem.
This process will probably expedite a repair if there is an issue as Dodge was going to have to do a similar process before they'd authorize a rebuild.
Good Luck</FONT f>
