If I use an OBD2 reader with Wifi and a smart phone app, will it read my MPG?

I've got a reader and just downloaded an App for it that reads all the info including MPG. Will my 97 be compatible with this function?

I'd walk out to the jeep, try it and report back. If it can indeed read the fuel delivery and speed, I suspect it can do the simple division.

Im on duty for a while but once I can I sure will try it. I hope it works, The OHCs read MPG so surely an OMB2 reader should be able too? I don't see why not?
