If Dorothy had never changed the Tin Man's oil, the Wizard probably would have just thrown away his spare heart. Show your car you have a heart with today's Groupon: for $49, you get five oil changes at D'South Automotive & Tire Service in Bossier City (a $99.99 value).
D'South Automotive & Tire Service's technicians treat engines to booster shots of EcoPower motor oil, a synthetic blend whose refinement process improves performance and reduces environmental emissions. Each 25- to 30-minute oil change includes up to 5 quarts of the specially engineered lubricant, which is used by the U.S. military and state troopers because of its ability to boost fuel economy, provide advanced protection against metal wear, and teach engines to purr the tune of "You’re A Grand Old Flag.” Technicians also swap clogged filters for a clean replacement, top off fluids, and pay house calls on components such as the belts and hoses. After redeeming the first oil change within four months, customers will receive a card valid for four more transfusions, to be used every time the engine turns sluggish or the pistons demand hazard pay.
