I should have written a follow-up. The guy that said to take my car in and they would follow me was the general manager.

The next week I called to book an appointment and the service manager said he didn't know what the general manager was talking about and he would just hook it up to a computer and it would cost me $60 so I decided not to pursue it.

I've been taking the fast odometer into account when calculating fuel economy.
