That RPM to MPH combination seem a little low on the RPM scale. What transmission, tire size and gear ratio combination does the XJ have? I think the 4.0L power band is about 2300 to 2500 RPM and should yield better mileage.
i tried last week what you were saying, keeping my RPM's around the 2300 range. i got 13.4MPG i think i will just go back to my 1700RPM's
