Why Am I only getting 11 miles to the gallon?

You got to get that taking into the dealership.
8 MPG and now 11 MPG!!!!!!!!!!!!!!!!!!!!!!!! That is CRAZY. Something isn't adding up here. Either your math is wrong, on board computer is messed up, or you have a 16 yo kid taking gas out of your tank at night to put into his or her car. I tend to think the later.
Even a mechanical issue I doubt would cause you to drop that far. Bad sensors, air filter, etc. etc. usually will only add up to a 2 to 5% drop in MPG. No way you should be getting less then 16MPG in a 530i. You should be more like 18MPG to 22MPG. Plus with a mechanical issue chances are your going to have a warning from the car that something is wrong.

I get about 26 mpg on average in my 525. I can just barely see 31.5 mpg's on the highway and have seen as low as 20 mpg's with a heavy foot in the city.

I think I'm going to have to do a complete tune up to the car. I replaced the cabin air filter. Spark plugs aren't due till about another 12k miles. The engined was checked when I changed the brake pads and rotors last week. The one thing I'm noticing now is that my 530i doesn't accelerate like it used to. It usually takes a few seconds before it picks up and shift to the right gear. I just don't want to imagine how much a complete tune up to this car is going to cost me at BMW of Manhattan. Never done it before, since I got the car a year and a half ago. Has anyone done it? If so, how much was it?

I'ts the steptronic 530i. I just recently got it up to 11 miles per gallon. Before it used to be 8 miles per gallon. I use the a/c occasionally because I'm in New York, so sometimes is hot and sometimes is not. But I really have to do something about this. Paying $4.60 a gallon of premium gas and having this problem is a real killer to my pockets.
