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?

Sagacar and welcome to the Chrysler Minivan Fan Club Forum. We hope your experience here is a pleasant one. Following are some tips to help with giving / receiving information, but firstly, your mpg problem.
- Perhaps your computer is already using US gallons rather than miles per Imperial gallon.
- The conversion mpig to mpg is 0.83. So, 24 mpig X .83 = 19.9 mpg whereas you show 19.
- Common factors affecting highway gas mileage are driving style, terrain, wind conditions, speed, load in / on the vehicle, and air pressure in the tires.
- 23-24 miles per US gallon sounds right (expected) for your vehicle
Jason's suggestion is what I would do. My computer often shows higher, by a mpig or two, than calculated from fillups.
