Is it me? or is my y33 really getting less than 10 miles per gallon (City)? :mad: Doesn't seem too bad on the highway. Just bought it (2) weeks ago.

spark plugs
over oiled K&N fouling the MAF
O2 sensors?

I don't own a Q so don't take my word for it, but look at the above link.

10 MPG definitely sounds low.

OTOH, 2 weeks of ownership probably isn't long enough to get a feel for what the fuel economy is going to be, over the long haul. Personally, I'd wait a few more weeks to see how far my next couple of tankfuls took me before deciding if there's a problem.

SHARP looking car, BTW - Welcome to the forums!

A while ago I used to drive my car in the city... About 5 miles, never got above 50MPH, lots of stop and go. 10-12MPG was not uncommon. I think once in the winter with lots of warm-up time I saw a low of 9MPG

If you can get 20-22MPG on the highway, I wouldn't worry about it.

Thanks a million for the input. I have read and taken all replies into consideration. I will give it a little more time, and monitor the gas mileage on both highway, and in city. I love this car by the way.
