You may be right, it sure doesn't seem like there is a consistent problem for all, nor a consistent fix for those with a problem. At one point I suspected a convergence of the oil rings and the EGR system in some mysterious way, but I know some with clean EGR systems and use Rotella who still have oil burning...so I don't know really.

Too bad the earlier 3.2Ls aren't an easy swap, my Trooper burns close to zero oil. I burned maybe 1/4 quart on the last Moab trip, that's around 3000 miles, wheeling and all. And yes that was with Mobil One 5W30.
