(Reuters) - Western Conference leaders Chicago Blackhawks gave Edmonton an unhappy ending to their long road trip with a 6-3 victory over the Oilers Sunday.

Jonathan Toews and Steve Montador scored two goals each to lead Chicago's offensive march and the Blackhawks (11-4-3) won their third straight and sent the Oilers home in a spin.

Edmonton (9-6-2) fell to their third consecutive loss as they wrapped up a six-game road trip that saw them finish 2-4-0.

Montador netted both of his goals in the first period to give the Blackhawks continued scoring support from their defenseman.

We obviously have some talented guys on the blue line. Coincidence? I don't think so. We've just been practicing it and talking about it for a while, Montador told reporters after helping Chicago extend their conference lead to three points.

Toews added his second goal of the game 22 seconds into the second to quickly put the Oilers behind 4-1.

Edmonton got second-period goals from Jordan Eberle and Shawn Horcoff but could not pull any closer than two scores behind Chicago.

Duncan Keith converted a goal in the second for the Blackhawks who capped the scoring with Daniel Carcillo's wrist shot with 1:45 remaining in the contest.

Patrick Kane, Nick Leddy, Patrick Sharp and Marian Hossa all recorded two assists in the victory.

Former Blackhawks goaltender Nikolai Khabibulin managed 29 saves for the Oilers against Corey Crawford's 20 stops for the home team.

We needed to man up tonight and we didn't do it, said Edmonton coach Tom Renney.

If we're better in front of our goaltender and pay attention to the detail that's required to set up your offense, our goaltending is going to be good enough every night.

Blackhawks defenseman Brent Seabrook suffered a lower-body injury in the second period and did not return.

Chicago will now be tested with a six-game road trip of their own beginning in Vancouver Wednesday.
