As a retired Service Manager…
As a retired Service Manager with factory certifications, where you live will determine the service. If you live say in New England, nothing is flat, uphill, downhill, traffic congestion, weather, all these have various dealer recommendations based on their customers driving. It harkens back to the day when people performed preventive maintenance instead of waiting for a breakdown. Now we're just a throw away society, why sped money to protect an important investment!
