ScanGauge II

An interesting product if you're lamenting the fact that Jeep did away with the oil pressure gauge, etc., is the ScanGauge II.

It does 3 different functions: (1) reads and clears "check engine" (MIL) codes, (2) it shows you up to 4 digital data items at a time, and (3) it has a sophisticated trip computer for keeping track of MPG, etc.

I hooked it up to the ODB-II port under the steering column and velcroed it to the top of the instrument cluster:

You can see it sitting in my garage idling :) so the engine is using 0.6 gallons per hour, the coolant temp is 190 degrees, and the air intake temperature is 134 degrees. Pressing one of the white buttons lets you change the data value displayed there.

I haven't tried the trip computer functions much, but it does give a good instant MPG reading and automatically resets for each day's travel. I also haven't had much chance to use the code reader, knock on wood. :)
