A car, like a barbecue, is one of man's most precious possessions, and like a barbecue, it needs to be regularly oiled to keep steaks from sticking to its grill. Protect your ride from the road and roadside hazards with today's Groupon: for $18, you get a full-service oil change (a $37.99 value) from either of Victory Lane Quick Oil Change's two Tulsa-area locations.

Starting with a speedy replacement of the oil filter and up to five quarts of oil, Victory Lane's friendly team of motorcar medicine men will quickly and efficiently administer a full wheelmobile physical, checking the battery, transmission, power steering, tire pressure, and differential fluids. Your spoiled subcompact will also receive a complete chassis lube, and the air filter and antifreeze level will also be checked and can be replaced (if needed) for an extra charge. Today's deal will also earn customers $10 off their next oil change, allowing them to keep their car's insides in fine shape throughout winter months.
