In a previous thread (Never Change Oil?), I posted how my 2009 T&C used a quart of oil every 1k miles. Neither Pennz Platinum nor Mobil1 made a difference. I am 1400 miles into my current OCI using Pennz Ultra 10w/30(old formula). The sump is down about .75 quarts and holding steady. I had intended to do 10k to 15k mile OCI's since I would be adding a quart of fresh oil every 1k miles. I had resigned myself to accepting the consumption issue, but it would appear that Ultra may be reducing the consumption, although it is a little early to tell. I am guessing the low NOACK is a factor. The plan will be to stock up on old formula Ultra while it is still available. Ten or twelve jugs should get me through the serviceable life of this vehicle. I will push for 8k to 10k mile OCI's backed by a UOA.
