Hmmm - your trucks sound too new to be needing fuel injector cleaner...
unless the gasoile in your necks of the woods is about as high quality
as crude oil... I did my first MPG averages with the new Ram and I get
a combined MPG of about 13. Assuming that my tires are the correct size
and that my speedometer is reading correct.
This is with about 850 miles of driving with 500 miles being open
highway. This is a full size Ram with a 360, auto, and 4.10 limited slip
gears, and Magnaflow catback resonator - and a VERY lose nut behind the
wheel. I would say your MPG definatly is not normal. The 4.7 even
with auto trannys should average better MPG than that. Its lighter -
more powerful and more efficent than the old 318s.
As for whats causing it? check all the obvious things - ignition
componants, tire inflation (which many people dont realize will REALLY
hurt your MPG if your tires are improperly inflated).
Also dont rely on the overhead computer for MPG accuracy. Do it the old
fashoned way. Miles driven divided by gallons used.
