Like an Olympic sprinter with his head stuck in a stairway banister, vehicle engines desperately need lubrication if they're going to run properly. Oil up with today’s Groupon: for $16, you get a conventional oil change and a 15-point vehicle inspection at Big G Tire Pros' location in Bridgeville (a $32.99 value).

Big G Tire Pros' staff of technicians maintains horseless chariots and puts minds at ease with a variety of automotive services. A 30-minute conventional oil change swaps out each vehicle's weary lifeblood for up to six quarts of fresh, engine-lubricating ambrosia, while also changing basic filters. A 15-point inspection tasks the keen eyes of mechanics with checking key automotive systems, yielding insight into the condition of the transmission, hoses, hose clamps, and belts while also examining the air-conditioning, cooling, and charging systems. Coolant and wiper-fluid levels receive a professional scrutinizing, and oil-leak jailbreaks are completely halted. After analyzing the tire wear, preternaturally gifted technicians determine tire-pressure levels via esoteric soothsaying, and conclude the inspection by checking the shocks and lubricating squeaky door hinges.

Big G Tire Pros protects its customers with complimentary roadside assistance, a warranty that comes with all Big G purchases. Stranded motorists can call in the warranty and receive towing, lockout, jump-start, and flat-tire-changing services as well as fuel, oil, fluid, and water delivery for especially dehydrated vehicles.
