To start. I only started keeping track of my fuel economy after I installed my 63 series K&N intake for the V8. I have no data to suggest what I might have been getting before hand, and the general consensus is the on-board mpg calculator is off by a few numbers.
Originally I had intended this to show possible gains with the intake installed. The readers of this thread could make their own judgement on weather it might be a potential upgrade if your looking to boost MPG. After all there are a number of threads on the forums regarding that topic.
What ended up happening during my logging of this information was a realization that octane rating has far more to do with MPG than I thought.
The first data point is using 87 octane. The next 3 data points I used 86 octane. Clearly there was a loss . The high point was using 90 octane. This was a substantial difference from the 86. The last 3 data points and what I am using now is 88 Octane.
What does this mean? It may be more beneficial to fill up with higher octane (90 if available) than attempt to purchase aftermarket products that may or may not work.
Its a little hard to quantify the difference between MPG gained / money spent to buy more expensive fuel but you can probably figure it out with your local fuel prices.
