The Valvoline Instant Oil Change of Naugatuck features a fast oil change service. There are three different stations that you can drive your car into (it resembles a car wash), and you literally sit in your car while the service is performed. It takes about 10 minutes to complete this and includes a full check of your vehicle. This includes a check of the lights, tire pressure, windshield fluid levels and an engine diagnostic check. With your oil change also comes a coupon for a free car wash down the road that is good for seven days after the date that the service was performed.
