Maintaining a car’s health involves a great deal of patience, an excellent roadside manner, and a willingness to croon like Mary Poppins while doling out cherry-flavored brake fluid. Keep vehicles in top form with today’s Groupon: for $18, you get an oil change at your home or office from E-One Automotive Mobile Garage (a $35 value). There is an additional charge for service locations outside of Vanderburgh County, Newburgh, and Henderson, Kentucky.

E-One Automotive Mobile Garage dispatches its jalopy whisperers on service calls to tend to ailing autos with a convenient, on-location oil change. Upon arrival at your home, office, or repurposed airplane hanger, an ASE-certified technician deftly swaps out grizzled old oil from wheeled steeds in 10–15 minutes. Thirsty motors get treated to up to 5 quarts of young oil as well as a new filter eager to do battle with friction and ensure that the engine remains cool enough to switch a jukebox song with just the pound of a fist. Once tanks have been topped off, a visual inspection of fluids, wipers, and smoke-screen deployers ensures the vehicle’s road readiness. E-One arranges oil changes around the schedules of their clients, affording busy motor-buggy parents the chance to pencil in an oil change around work or daytime appointments.
