A A C Auto Clinic's ASE-certified technicians work to keep drivers safely and smoothly rolling across American roadways. During an oil change, mechanics replace motors' used oil with up to 5 quarts of 10W-30 oil, quickly screwing in a new filter when the car's not paying attention. For those who choose the first option, a tire rotation switches wheels around so rubbery soles can take turns being in front and avoid uneven wear and tear. Technicians can also install a new set of wiper blades (up to 21" long), which help drivers see the road while driving through snow, sleet, or Rain Man posters. During the 30–45 minute service, the shop's play area distracts kids as well as adults who are still children at heart.
