O'Brien Auto Group's factory-certified and trained technicians keep autos running friction-free, swapping grimy lubrication for conventional or synthetic motor oil. After a hydraulic Hercules lifts the vehicle skyward, a technician carefully drains its reserve of grease-infused oil. Steady hands then pour up to 5 quarts of synthetic or conventional oil into the reservoir, providing smooth-gliding efficiency for pistons and miniature catapults that make vehicles go vroom. Conventional motor oil provides long-lasting lubrication for most cars, but synthetic oil offers more consistent performance at extreme temperatures—ideal for summer road trips to Mercury. After autos are fully oiled, mechanics perform a complimentary 29-point inspection and thoroughly wash exteriors, making cars gleam like a body builder's slick pectorals.
