Scott Hartnell and Austin Watson scored, and Pekka Rinne made 34 saves for Nashville, which has won six straight.
The six-game winning streak is the longest of the season for the Predators and gave David Poile the most wins by a general manager in NHL history (1,320), passing Glen Sather.
"To be able to come back and deliver on such a big night for him was pretty special and something really incredible for us as a group to be a part of," Watson said. "Congratulations to Mr. Poile and his family. It's incredible."
Connor McDavid and Leon Draisaitl scored, and Cam Talbot made 38 saves for Edmonton (27-33-4), which has lost two games in a row.
"Mistakes hurt us," Oilers defenseman Darnell Nurse said. "We fought with the right effort and a lot of our guys had really strong games. As long as we have that compete level and that effort we will be on the right side of the board most nights. It was definitely tough to lose that one, but it is one we can grow from."

McDavid scored at 11:01 of the first period to give Edmonton a 1-0 lead. He picked up a loose puck in front of the net and deked Rinne.
Draisaitl made it 2-0 at 19:07 on the power play with a wrist shot from the left circle that beat Rinne glove side.
"The first period was tough, I don't think we played that bad," Predators coach Peter Laviolette said. "The chances were in our favor. I like some of the things we did. Our defenseman didn't have his stick on the first goal, and the second one they were able to score a goal off the rush on the power play."
Hartnell scored at 16:28 of the second period to make it 2-1, capitalizing on a turnover by Ryan Strome deep in the Oilers zone. Nick Bonino knocked Strome off the puck in the corner and set up Hartnell for a one-timer in front.
Arvidsson tied the game 2-2 at 19:50, converting a pass from Filip Forsberg on a 2-on-1.
"It was a big goal with  seconds left," Arvidsson said. "Filip made a big pass and I just had to have my stick down and put it in the net."
Arvidsson put Nashville up 3-2 at 14:52 of the third period on a rebound off a shot from Forsberg.
Watson made it 4-2 at 16:50 on a one-timer into an open net after a pass from Ryan Hartman.
"I thought it was a fairly evenly matched game and when all was said, we made a few more mistakes than they did, and they capitalized more on our mistakes than we did on theirs," Oilers coach Todd McLellan said. "We played a solid third period, there wasn't much going on either way, but we had a couple of breakdowns from veteran players that really cost us."

They said it
"I think we have that confidence as a group that we know that we can score goals if we stick to what we're talking about and stick to what [coach Peter Laviolette] is preaching, then we're going to be able to score goals and come back in the hockey game and we were able to do that." -- Predators forward Austin Watson
"We didn't make a lot of mistakes, but they made us pay for the ones that we made. We had enough chances to extend the lead in the second period and we weren't able to capitalize on them." -- Oilers forward Milan Lucic
