18MPG reliably - stop&go&hwy, Mostly in traffic.
My OBC says my car better than yours.
I'm telling you I have never averaged below 17MPG since I have owned the car. I regularly exceed the speed limit and my commute always involves some stop and go.
I also get better than 18 MPG city & highway
OBD average speed 35-40 MPH.
On a road trip I usually get 23-24 MPG, an OBD average @ 85-90 MPH.
My E38, 740 (4.4 liter) gets 20+ MPG with an OBD speed average 85-90 MPH.
The highway gas mileage for both would be better if I didn't have to keep slowing down to get arround the fast lane hogs and accelerating back to speed.Rod...
