I've only had 2 brand new cars, both manual transmission Toyota engined cars-did some up & downhill driving, no WOT, leaving it in a lower gear going downhill to seat the rings, neither one ever showed any oil consumption between OCs, AT ALL! Now if I was buying a new Demon, a Scat Pack Charger, or a Shelby GT-350 Mustang, it better not have been driven anywhere but off the delivery truck. I've seen what new car salesmen do to demos-it ain't pretty!
