xSp33dD3mon · 09-02-2012, 05:56 PM

I have a 2011 328i coupe, im averaging 16-17 mpg. just wanted to know if thats a normal mpg because i thought it was supposed to be in the mid to low 20s.

How are your driving habits?

What grade fuel do you use?

Lots of stop and go traffic?

usually 40mph on streets, 80 mph on freeway, i use premium fuel, 3 back to back stop signs on my street, but other than that not too much stopping

Driving in traffic almost never yields good fuel economy so zero your OBC mpg readout and then take a 50 mile highway cruise at a steady 70~75 mph. If the OBC doesn't read around 28 to 30 mpg for that trip, you have an issue.

That's way too low. Could be the stop and go traffic.

+1. Reset and then try it on a stretch of highway. You're getting the cumulative readout since it was last reset.

That is what I get with my 328IX E91. The best ever was 18.5. 328IX is not known for good gas mileage. But I'm loving this car!
