Pistons and shafts overheat and seize up unless protected by a slick, shiny coating of oil, just like classical Greco-Roman wrestlers.

Since 1929, the Livingston Tire Company has taken pride in offering each customer outstanding service and trustworthy automobile care. Its ASE-certified technicians only need about 45 minutes to complete an extensive oil-change package, beginning with a thorough de-gunking of vehicular veins that removes blackened crude and old coffee grounds, and inserts up to 5 quarts of fresh standard or synthetic lube. After a filter replacement, a tire rotation works to maintain even wear across all rubber treads, and a brake inspection, done while the tires are off the vehicle, can help ensure that there are no nasty surprises during nightly cliff-side races. Finally, a 19-point safety and maintenance check goes over crucial car mechanisms, examining them for damage that might waylay an everyday road warrior.
