Preventative Maintenance

To keep your vehicle operating reliably the fluids and filters must be serviced at regular intervals. Modern automobiles require specific fluids for each application and failure to follow manufacturer specifications can lead to a catastrophic breakdown. Our technicians are knowledgeable in keeping your vehicle serviced with the proper fluids, right on schedule.

This is not a normal oil change. Whether your vehicle needs conventional, high mileage, synthetic blend or full synthetic oil, the Napa Signature Service Oil Change is the right oil change. We check and fill the essential systems and components of your vehicle letting you know of anything it may need.


Your vehicle requires its fluids be kept within manufacturer specifications to continue functioning reliably. Whether it’s the transmission, brake, coolant, fuel, or power steering; we keep your car’s vital fluids at peak operating condition.

Over time, everyday driving can cause the steering and suspension geometry of your vehicle to deviate from the manufacturer’s specification. Incorrect vehicle alignment can cause premature tire wear and even reduced fuel mileage. Our certified technicians use industry leading alignment technology to measure your vehicle’s steering and suspension geometry and adjust it back to factory specification.


When one of the many components on your vehicle inevitably fails, our certified technicians are here to help by using the most advanced diagnostic equipment and years of expert experience to make sure the repair is done right, the first time. After the problem is diagnosed, don’t settle for bargain auto part store replacement parts, NAPA has been in the auto part business since 1936 and is committed to supporting their customers for many miles down the road after the repair is completed.


Let’s talk about your suspension – you know, the system that connects your wheels to your vehicle, controls your handling and delivers a good ride. Your suspension is critical for proper steering, stopping and stability. 

Your brakes are extremely important. Having good brakes just keeps you out of trouble. You’ll want to carefully maintain your brakes.

Transmissions are heavy duty pieces of equipment that are designed to last a long time. But like any other machine, they’ll eventually wear out and need repair. So let’s focus on what you can do to push that day off as far as possible. 

Your drivetrain is the last link in transferring power from the engine to your wheels. It’s made of strong parts that last a long time – but they can run into trouble.



Nothing is more important to the performance and safety of your vehicle than the tires connecting it to the road, as the tread wears, the geometry designed to evacuate water and provide traction in the winter months diminishes. We carry the top brands for a variety of applications to keep you in control no matter what the weather conditions are.


We take care of our customers and their vehicles; that’s why our customers make it a point to come back. Take a look at what some of them are saying about our automotive expertise.

They were so hospitable and knew what needed to be fixed. They were upfront and honest with me. I took my car in to have the work done and the staff was professionally and did the work in a timely manner so I didn’t have to be without my car! I would strongly recommend them to anyone in the area!

Fabulous customer service and run by a kind and knowledgeable older gentleman who will give you a fair deal and tell you exactly what’s wrong with your potential car. The lot offers cheap deals and obviously they will have some issues but this isn’t a problem because they won’t hide them from you.
