Yes, it's strange. Up here, our Mobil HM blend has had that for a very long time. A high mileage vehicle should be out of warranty, so the certification should not be an issue. Then again, if some people don't think it's the appropriate oil (no matter how many miles they have), they won't touch it. And I'm sure that the oil companies don't mind selling HM oil for new cars, either, from a financial perspective.
