I was thinking about that, but here is my counter logic: For $160, I can still do a significant number of changes that will benefit my car, rather than just logging the change. Additionally, even with a Scan Gauge, I still wouldn't be able to track the efficacy of the modification over time, since it would be followed quickly by another modification.
As it stands, my logging gas used at fill up is still fairly accurate (probably no greater deviations than would be caused by the effects of variations in driving conditions), costs me nothing, and still has the potential for frequent updates (as with the Scan Gauge).
Maybe the answer is just more frequent fill ups. 1/3 of a tank used between fill ups still equals 4-5 gals, or roughly 100 miles with my current mpg.
