Pistons and shafts overheat and seize up unless protected by a slick, shiny coating of oil, just like classical Greco-Roman wrestlers. Keep your engine parts from throttling each other with today's Groupon: for $25, you get a spring fuel-efficiency checkup, which includes an oil change, battery test, tire rotation, and 39-point inspection, at AAA Car Care Plus (a $150 value). This Groupon is valid at the Sawmill, Grandview, Berwick, or Lancaster AAA Car Care Plus facilities.

The ASE-certified mechanics at AAA Car Care Plus revive winter-worn wagons with an array of preventative-care services, available for most domestic makes and models. The spring fuel-efficiency checkup, which lasts 90 minutes or less, begins with a lube and oil change, including a new oil filter and up to five quarts of conventional motor oil (a $21.64 value; synthetic oils are available for an additional fee). Next, motor maestros conduct a 39-point visual inspection (a $22.67 value), followed by an electronic battery starting and charging test (a $44.39 value). An auto doctor will diagnose brake-pad health via visual brake inspection (a $44.39 value), and administer a tire rotation to ensure safe tire pressure, tread depth, and sense of equlibrioception (an $18 value).
