The "F" averages around 12 mpg. Mostly highway (non-X-way) driving. I believe it has a 2.93:1 rear axle ratio. It would probably do a bit better if I could keep my foot out of it.....

My 300K with crossrams and (rich running) competition AFB's gets 11-12 mpg on long trips with top down. My 70 Charger R/T with single 4bbl , 4speed, 3.54 Dana usually gets 16-17 mpg at "cruising" speed in overdrive. Depending on how often you drive the car and under what conditions you may want to swap in a 2.76 ratio. They're usually inexpensive... don't forget to change to the correct speedo pinion gear so your speedometer is correct and you'll probably pick up a few mpg's Mike Laiserin [Non-text portions of this message have been removed] To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/ Yahoo!
