The Jiffy Lube Signature Service Oil Change handles more than just the replacement of vehicles' engine juices with up to 5 litres of Pennzoil conventional motor oil. Each service comes standard with a fresh-from-the-box oil filter, plus a comprehensive lineup of other vehicle-maintenance checkups, an exterior window wash, and interior floor vacuum. Trained technicians entreat cars to say "Ahhh" before quenching automotive thirst with top-offs of transmission, differential, transfer-case, power-steering, and windshield-washer fluids. A detailed inspection enforces the well-behaved manners of the antifreeze and coolant reservoirs, engine air-filtration system, serpentine belt, wiper blades, and exterior lights. Finally, techs wield professional testing equipment to examine the battery's amp capacity, the starter's electrical draw, and the alternator's electrical output to make sure cars start quickly with every turn of the key.
