eats up to much gas. on 2008 BMW 328xi

Just purchased car used. We do love the car but it does eat alot of gas. Is this normal? Do you think there could be a problem?

How many miles does it have? Is it regularly maintained? Is there any warning light on, like Check Engine?
What is the fuel consumption?

depends on the make model and how you drive, yet, it sounds like a problem... get a full tune-up, plugs, cap, rotor, wires, and all filters... then fill up and at next fill up check milage vs ammount of fill up in gals/ = miles per gallon, then check against dealer specs on fuel consumption ratings...
Use better gas ... Shell premium is good. Get what you pay for.
