Cars need regular oil changes to keep them running in top form, just as winning racehorses need periodic blood transfusions to keep the drive for victory coursing through their veins. Treat your chariot like a champ with today's Groupon: for $20, you get an oil change and an inspection at R&T Performance in Sparks (a $42.50 value).

Technicians at R&T Performance—a recipient of the ASE Blue Seal of Excellence—bolster four-wheeled friends with precision vehicle service. During each oil change, technicians drizzle mucked oil from the car, unfasten the contaminated filter, and safely dispose of them before they attempt to win the engine back with a hastily composed love song. Up to 5 quarts of conventional oil slither through the car, slickening metallic components, and a clean filter takes its place next to the motor. Once sufficient oils have been integrated, mechanics administer a nine-point safety inspection, snooping from the cooling system to the tires and seven destinations in between. Techs gauge rubber for proper air pressure, inspect the suspension, and make sure brakes haven't lost confidence from reading the Kelley Blue Book.
