I have a question regarding my 96 Dodge van.
There is a large difference between the city and highway mileage. The
vehicle gets around 20 - 21 MPG on the highway but only around 9 - 10
in the city. I'm careful not to be a leadfoot and do follow the speed
limits. I just put in a new serpentine belt (it was squeaking), air
filter and PCV but that doesn't seem to have done much. The van has
about 50,000 miles has a 5.2 motor with automatic transmission.
What else can I check or fix to help bring up the city MPG?
