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 $20, you get $45 worth of oil-change services at Flyin’ Fisch Synthetic Lubes in Kitchener. Since 2007, Flyin’ Fisch Synthetic Lubes has rendered a range of automotive services, including 1 yr./40,000 km warranty approved oil changes. During the oil change, Flyin’ Fisch’s certified mechanics will replace old, worn-out oil with 3.5–5 quarts (depending on automobile size) of 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, Flyin’ Fisch uses and distributes Amsoil products, a leader in synthetic lubricating oils. The price of an oil change varies by the size of the vehicle, but prices for an oil and filter change and inspection usually run around $35 for a small car, $68 for a bigger vehicle, and somewhere around $3,000,000 for a medium-sized space shuttle.
