I am with condom, my first thought was "did he lean the mixture"?
Also, what altitude was the trip done at?
Gotta admit it's been a long time since I flew a piston and probably ten years since I flew a 172, but if I was guessing I would say a mixture of perhaps not quite full tanks and a rich mixture may have been the cause.

PS: I think we all have a story about the inaccuracy of Cessna fuel guages!!
