The fourth episode of Oil Change is about a long, cold winter’s stretch of tough games. There is a very good chance that those games after Christmas through January will make or break the Oilers’ chances of getting into the playoffs. And they will also certainly help inform management’s decisions about what to do, or not do, with the NHL’s trade deadline fast approaching.Although the Oilers’ game to game play and win-loss record remain paramount, this episode, airing when it does near the start of the festive season, also gives us a chance to get to know some of the players a little bit better away from the rink – perhaps decorating a Christmas tree, shopping for their kids or making community appearances. ****Oil Change, Aquila Productions’ popular and critically-acclaimed documentary series about the Oilers’ quest to go from bottom feeder to championship contender comes to Citytv this year. Using state-of-the -art, high-definition video cameras and audio-recording equipment, the Aquila follow the team closely on the ice at practice and during the heat of games, in the dressing room, training rooms and coaches’ offices before and after games, away from the rink at home, out in the local community and on the road around the league. We will see and hear the Oilers with their game faces on, with their hearts on their sleeves, and with their guards down during good times and bad alike.
