Jiffy Lube- STC, Warrenton

The highly trained technicians at Jiffy Lube tend to about 24 million customers each year with services such as the Signature Service Oil Change package, which promotes the longevity of each vehicle. Staffers acknowledge that oil plays a crucial role in maximizing the lifespan of each car—it cools the motor and prevents moving parts from deteriorating. More than 20,000 technicians who have completed an extensive training program certified by the National Institute Automotive Service Excellence (ASE) nurse vehicles at Jiffy Lube.

In addition to performing oil changes, Jiffy Lube's savants perform air-filtration, electricity, and windshield services, among others. The technicians' quality pledge includes a commitment to transparency, which stipulates that they will inform car owners of any necessary services, only complete a service after it has been approved, and refuse to replace windshields with saran wrap.
