Oil is as vital to a car as water is to a fish, which is why a total replacement of each is recommended after about every 3,000 miles traveled. Keep fluids fresh with today’s Groupon: for $25, you get a full-service oil change (a $40 value) and wiper-blade replacement (up to a $16.99 value each) at Grease Monkey (up to a $73.98 total value), redeemable at three Seattle locations.

Grease Monkey’s professionals provide car pilots with wide-reaching, proactive auto treatments. The road to extended motor-vehicle life begins with the swapping of exhausted oil for up to five quarts of the fresh stuff and a check and top-off of fluid levels. A new oil filter takes the place of the old, filthy gunk-catcher, keeping particulates from circulating and damaging vital engine parts. Wheel wizards then check tire pressure, filling each rubbery disc with a blast of air if necessary, before vacuuming interior upholstery and gently cleansing exterior windows. A pair of gleaming new wipers then ousts the car's old and tarnished blades, assuring that windshields will never be caught off guard during sudden sandstorms triggered by ancient amulets.
