Despite their mechanical nature, cars are sensitive and must be groomed, protected, and lulled to sleep by the sound of a mechanic ripping up a Haynes manual. Show your car you care with today's Groupon: for $18, you get an oil-change and car wash at Pit Stop U.S.A. (a $36.95 value), valid at the Eugene and Springfield locations.

Pit Stop U.S.A.'s friendly technicians share decades of automotive experience to safely and efficiently spruce up engines during 10-15 minute oil changes. Five quarts of fresh Pennzoil lubricant grace car bellies to flow through brand new filters and keep pistons pumping smoothly. Techs recycle the used oil and filter, helping them avoid landfills and finally earning conservationism merit badges, then check and top off important fluids, such as transmission, brake, and power steering solutions. A quick inspection assesses air filtration in the cabin, strength of serpentine belts, and light operation to ensure safe driving at night. Following services, car owners roll through drive-in bays that scrub car skins, spacious enough to accommodate RVs, oversized trucks, and Weinermobiles.
