[s-cars] Gas mileage on your UrS?

[Ivan Demkovitch]

After yesterday $50 fill up I became little worried :-)
I get 15-16mpg city/highway driving. I get about 23-24 when driving on 
cruise control at 80mph.

Yes - I have heavy foot and everything. I compare to my 540i which I drive 
on a same manner and even faster. I constantly get 18-19mpg with same 
driving out of V8 4.4L motor..

Is it ok gas mileage? Or something could be wrong? I had O2 sensor replaced 
recently with universal 3 wire sensor. I also have Stage 1 chip

Thanks,
Ivan
