Peter Leven inspired Oxford to a comfortable victory at Aldershot that moves them up into the play-off places.
The Scot set up the opener with a fine volleyed cross, which Jon-Paul Pittman headed in, and Michael Duberry scrambled home a Leven corner for 2-0.
The midfielder got himself on the scoresheet in first-half stoppage-time when he fired home from an angle after being set up by Pittman.
Shots rarely threatened although James Collins forced a save from Ryan Clarke.
Oxford moved up to seventh with the win, while Aldershot remain 16th, but they are now only six points above the bottom two.
Pittman's close-range opener was his second goal in his two games of 2012 after failing to score in seven matches for Oxford in 2011.
The former Wycombe man was replaced after 76 minutes by fellow summer signing Deane Smalley, who hit the woodwork seconds later.
VIEWS FROM THE DRESSING ROOM
Aldershot boss Dean Holdsworth told BBC Surrey:
"We came up against a good side with a lot of quality players. We created chances but couldn't put the ball in the net. We got punished in the first half and that's the reality.
"We'll work hard and make sure they don't lose confidence. There's no quick fix. It's about going out there and handling the pressure.
"I'm frustrated but I'm a realist - we can't compete with Oxford in terms of finances and players."
