2008 Hyundai Azera Question: Why would this car use so much gas, what mechanically
Answer #1DaveJHM June 26, 2011, 05:42Master
There are many reasons a vehicle can use too much fuel. Some are mechanical and engine management issues, some are physical attributes.
I would recommend a diagnostic assessment be carried on on the drivability side - including the engine performance.
At the same time - check for any attributes that may be slowing down your vehicle, requiring more fuel to operate your car, etc. Things like bug deflectors, exterior trim.
