Cogliano scored in overtime for an NHL-record third consecutive game and the Oilers defeated the St. Louis Blues 4-3 on Tuesday night.
Cogliano took a pass from Sam Gagner with 4.9 seconds left for the victory.
The 20-year-old Cogliano said his accomplishment is pretty special.
"It was pretty shocking," Cogliano said. "It's hard to believe something like this, it's certainly a feeling I will remember for the rest of my life.
"Things like this don't happen often. I think I've just been really lucky to have those opportunities go in for me. But yeah, three in a row, that feels pretty good."
It was the seventh victory in the past eight games for the Oilers.
Oilers coach Craig MacTavish says they were lucky to get two points after allowing an early 3-0 lead slip away.
"That was a wild game," he said. "Kind of hard on the heart for this time of year. You take a 3-0 lead and you think maybe it is going to be an easy night for us.
"We have a young team and you got seduced into thinking it's going to be point night. Hopefully, we have learned a lesson here."
It was the fourth consecutive loss for the Blues, who have lost 10 of their past 11 games.
Blues coach Andy Murray admitted it was special to see Cogliano come through again, though it's not likely to be a favorite memory.
"Obviously we scouted the two previous wins and saw the Columbus one and saw the one in Chicago, and he was on the ice and put the puck on his stick with a few seconds left in the hockey game, so good for him, but I didn't really enjoy watching it," he said.
Edmonton got off to a quick start, scoring a little under three minutes in on its first shot. Stortini hit the corner behind Blues goalie Manny Legace with a wrist shot.
The Oilers took a 3-0 lead, scoring on a pair of power-play goals. Gagner fed a pass back to Stoll at the point on a two-man advantage and he sent a shot into the back of the net.
The Blues got a break late in the period to cut Edmonton's lead. Boyes' long dump-in shot took an odd bounce off the boards and came out to McDonald, who had an easy tap-in with Oilers goalie Mathieu Garon badly out of position.
St. Louis got back into the game only 40 seconds into the middle frame when Stempniak batted a pass from David Backes between Garon and the post to make it 3-2.
The Blues continued to pressure and tied the game a little over 11 minutes into the second as Paul Kariya made a nice feed from behind the net, allowing Boyes to score his 37th of the season.
It was the fourth and final meeting between the two teams this season. Edmonton ended up winning the series 3-1.
