Before people learned to manage automobiles’ oil addictions, cars snuck out of garages to go on all-night benders, doing lines of petrol off the backs of scooters. Keep a wheelmobile from running amuck with today's deal: for $13, you get a standard oil change (a $29.81 value) at McMahon Tire & Car Care, an auto shop with an A+ BBB rating.

During a standard oil change, McMahon Tire & Car Care’s certified mechanics will replace old, worn-out oil with fresh-faced young fluid, straight from lubricant college and ready to take on the heat, dust, and incredible pressures of today's high-octane internal-combustion world. To help new oil adjust to its new job of safeguarding precious moving parts, gaskets, and various shafts, a fresh oil filter is included. Filters are always replaced at the same time as the oil, ensuring that all of the contaminants from old oil are removed from your car's system. Used motor oil must be disposed of properly; the professionals at McMahon follow all disposal protocols to the letter.

Valid oil changes of up to five quarts, enough for all standard light-duty automobiles.
