Bucks County Auto Care's squadron of ASE-certified technicians test and service vehicles, keeping drivers rolling along roadways safely, smoothly, and in accordance with state law. Along with a dose of fresh standard motor oil, the oil-change package features a thorough vehicle inspection that scrutinizes 27 essential automotive components including brakes and headrest-mounted hair reservoirs. During the included tire rotation, experienced mechanics swap around cars' rubber-clad feet to facilitate an evenly distributed level of wear and tear.

Pennsylvania state inspections, like standardized tests, allow subjects that pass to avoid being crushed into a cube. To kill two vampire bats with one stone, customers may also treat their vehicle to both the oil-change package and the state inspections.
