Could be all kinds of reasons why your friend is getting poor gas mileage. Those reasons range from driving style, (jack rabbit starts at streetlights / lead footed driving), aerodynamic drag, (driving with windows / sunroof open/closed, big ass'ed wing on the hatch, roofrack, etc), or vehicle maintenance / performance, ( improperly inflated tires , brakes dragging, driving with the A/C on, etc).
If your friend wants to see if he can improve his gas mileage, then have him do a tune up. Change out the air, oil & gas filters. Replace the PCV valve, distributor cap & rotor, spark plugs & wires. Take a bottle of fuel injector cleaner & pour it in the gas tank along with spraying the Intake Manifold & EGR valve with a can of carburator cleaner to clean out the carbon buildup inside. Also put the ECU into Diagnostic mode & test the Engine Coolant Temperature Sensor along with the Oxygen sensor. If any of those two sensor appears to be performing poorly, replace it. Also, check your idle and timing to make sure your engine is running at it's peak efficiency. Check your tire inflation & make sure the tires are properly inflated. Pull your wheels off & check to see if the wheel bearings are spinning properly & the brake pads are not dragging against the rotors.
All these little factors can add up and affect your gas mileage. Doing a tuneup doesn't hurt...it only helps your engine run better.
Anyhow...hope this helps...
