My Chrysler Grand Voyager LX 3.3, 2006 model, 36.000 km is new to me this spring. From highway driving (60 m/h) the trip computer reports 24 MPG, I expect 22 -23 from experience with my previous -96 Voyager 3.3, but the actual consumption is 19 MPG. Converted to US Gallon.

Can the computer be "that" wrong?

Is that poor mileage usual on 2006 model?

I have had the car to service while troubleshooting this situation, and they say "no error" and upgraded software.

What could typical be wrong in fuel system?
