The final episode of Oil Change follows the Edmonton Oilers through the last month of the 2011-12 NHL season. The young Oilers know they will not make the playoffs, but with head coach Tom Renney cracking the whip they’re determined to finish strong, earn respect around the league for their talent and work ethic, and lay important groundwork on the road to becoming a playoff team next season. Highlights of this episode include the Oilers’ second straight victory over Calgary, a raucous Battle of Alberta at Rexall Place that hurts the Flames’ own flickering chances of securing a spot in the playoffs. From there the Oilers take to the road, capturing seven of eight possible points against Nashville, Tampa Bay, Florida and Columbus in an impressive swing through the American southeast. A victory over Nashville is highlighted by veteran Ales Hemsky’s very first NHL hat trick. In a tough shoot-out loss against the Lightning we see Nikolai Khabibulin play his first game in Tampa Bay since he led that team to the Stanley Cup in 2004. Late season injuries to star Taylor Hall and other Oiler players force another round of call-ups from the team’s AHL-leading farm club in Oklahoma City. This time it’s centre Chris Vandevelde and power forward Teemu Hartikainen. Both young Barons impress with the big club -- Vandevelde scoring his first NHL goal in a victory over Columbus and Hartikainen netting a pair in a win against Anaheim. A much different injury-related feel-good story documents the long, painstaking but ultimately successful rehab of promising rookie defenseman Taylor Fedun. Fedun returns to full contact practice with the Oilers six months after the devastating broken leg he suffered on an icing call race in a pre-season game last fall.
