With more than 250 locations spread throughout the US, Latin America, and China, Grease Monkey is a recognized and respected name in the automotive service industry. The reasons for its success boil down to quick and knowledgeable service conducted by technicians who value each car's longevity above all else. The marquee service is the full oil change—no appointments are needed for the quick, yet extensive service, which includes a complete review of the car's needs in accordance with its owner's manual and astrological charts. But the technicians offer a variety of other services that are likewise dedicated to keeping cars healthy and at peak performance, including emissions tests and transmission, brake, and battery work.
