Routine maintenance and preventive care

It is imperative to keep up with today’s vehicle maintenance schedule. Engines under the hood are finely tuned instruments and it is important to keep up with the manufactures maintenance schedule to avoid costly repairs down the road. Our trained techs follow a set checklist based on your cars mileage in addition to a safety inspection. We also top off your fluids at no charge. We can typically provide a quick oil change while you wait and get you back on the road.

Changing your oil at regular intervals is important, but it is not the only item on your vehicle maintenance schedule.  Following your manufacturer’s mileage checklist is key to extending the life of your car. A good example is the recommended change to your timing belt.  If you delay the maintenance and the belt change, then you could experience catastrophic damage to your engine which could be avoided by following the change schedule.  The good news is that we can typically provide substantial savings over the dealership for the same service by not overcharging for many of the listed maintenance items. Stop by our office anytime to discuss and review your vehicles maintenance schedule.
