I think something is wrong with mine. I have been getting like 12 to 13 mpg. The best I have done is 21 but that was all highway. Around town it sucks gas like a hooker.

The dealer said to bring it in which I will once my splash guards come in.

 

I'm assuming you have an auto, sedanman? If so, are you using the shift paddles? Revving like crazy at or past 4000rpms? I wonder if an oil change will help. Under 15mpg is pretty crazy to me, unless you're driving like crazy.

 

Just thought I'd let you know that on the 3 fill-ups so far, only the first one was off by about 2 tenths from the readout on the dash. The other 2 were exact, which is pretty damn good considering the variables involved with filling the tank from different pumps, etc. In comparison to my Prius, which is almost always off by 1 to 2 mpg + or minus, that's pretty good.

 

I have actually been pretty good. Driving it for the most part easy until broken in. Hardly used the paddles and keeping it under 4000 so yes it's very strange to be getting 13 mpg. I still believe and hope it's nothing more then a reprogram of the computer.

 

Was my actual actual milage based on the latest tank refill, half commuting at ~40 mph and the rest city stop and go, not pushing it hard, 1250 miles now.

(the trip comp mileage got messed up with me pushing buttons til I finally found the one on the far left lower side of the instrument nacelle).

That seems about like my old one when the temps were low as they have been here this week.
