As usual, going into Rocha's for an oil change results not only in an oil change, but a thorough inspection of the vehicle and the vehicle's maintenance records on Carfax. As a result, it was determined that the battery was on it's way out, and that the front and rear differentials needed servicing. I was notified by phone of the needed maintenance in advance and in a timely manner. Given my permission to proceed, the required maintenance was performed in an efficient and timely manner and I was notified when my vehicle was ready for pickup.
