There are many owners here who do not have the oil consumption issue.

People have pointed to the clogged EGR and to the PCV as culprits. Some believe that the issue rears up early in the breaking in period. Unchecked, it becomes a permanent issue for the life of the engine. Know that not all PCVs are created equal; cheaper ones may not be as efficient just because they are new (mechanic's 2 cents).
