A new engine is tighter and that causes more friction. If the engine had to be bored / over sized for new and bigger pistons then that will cause poor fuel mileage too.

The gas mileage might be down a little at first, but once the engine gets broken in there shouldn't be much difference unless the cam or compression ratio has been changed.
