At Mobil 1 Lube Express, a troop of trained technicians replaces old oil with up to 5 quarts of new fluid, screwing in a brand-new filter to match. Then, they'll put on their safety caps and perform an inspection—which includes checking fluids, lights, belts, and tires—before turning steering wheels left and asking tailpipes to cough twice. Cleaners equipped with smudge-eradicating suds and dust-hungry vacuums move in next, targeting grime and fingerprint mosaics with a full-service wash and hand dry, vacuuming interiors, and applying Rain-X and triple-foam protectants for extra defense against the elements. An application of rust inhibitor protects metallic veneers from corrosion, and a coating of Bugg Off affords rides a layer of defense against clingy insects and children wearing trendy magnetic vests. Specialists will also blast away crud from carriage underbellies and decorate wheels and tires with sprays of Wheel Brite and a tire shine.
