I'd check the PCV system for some defect since this is the most easily remedied if the issue is there.
We also don't know if 90% of your driving is @ 85mph+ with frequent bouts @ WOT.
Driving style is docile. I don't beat on it, and ususally never drive more than 5 over. Consumption is static regardless of highway vs city, hot vs cold, etc. PCV is integrated in the manifold, so its not servicable. Had the dealer notate that consumption was occuring, but they were not concerned at the minimal rates. 1 quart per 2k is thier limit. I'm perplexed...
