Edmonton had not scored eight goals in a game since 2003, and it came at an opportune time. Phoenix was able to tie the game 4-4 on a power play goal by Peter Mueller. But the host Oilers regained the lead at 7:32 on Penner's power play goal.
Glencross scored twice in a 3:05 span and Stoll finished the scoring with an empty-net goal in the closing seconds.
Phoenix goalie Ilya Bryzgalov was pulled in favor of Mikael Tellqvist at the start of the second period after Bryzgalov allowed three goals on 11 shots in the first period.
Dwayne Robinson made his third consecutive start in goal for the Oilers and responded by stopping 34 of 30 shots.
