Like violins, cars announce their need for a tune-up by squeaking shrilly and leaking oil every time you play Mahler. Keep your ride purring pleasantly with today's Groupon: for $19, you get a full-service oil change and tire rotation at Bob Sumerel Tire & Service (a $55.95 value), valid at six locations in Columbus, Powell, Dublin and Lancaster.

The ASE-certified technicians at Bob Sumerel Tire & Service mend automobiles of all makes and models with a comprehensive list of services. To ensure smooth operation, mechanics offer engines fresh conventional motor oil during the 60-minute full-service oil change, also adding a new filter, which keeps contaminants from organizing anti-piston rallies at the bottom of the oil pan. Technicians then reposition each of the four tires, a ritual that evens out tread wear and brings balance to the vehicle's driving life, enabling better navigation through tight turns and along narrow sidewalks.
