I do, I have a Scangauge. The problem is at least on my car, it is actually pretty hard to track because the MPG is always changing significantly, even under what seems to be constant conditions like just cruising down the highway with a constant throttle position. I think some of that may be because there are basically no flat roads here for more than a few seconds and there are so many potholes that when I do get a few seconds of "flat" road I am always having to steer to avoid potholes. This makes seeing even relatively significant differences such as AC on vs off surprisingly difficult as normal variance is much more than the difference from most of the things I would be testing.
