I've taken a slightly different approach here..

I log the AVERAGE speed of my 328i per tank (usually 230-270 miles), and do tank to tank MPG comparisons..

I've plotted these in an effort to determine the best AVERAGE speed for LPG consumption.

In the chart below

Speed (MPH) is along the bottom

MPG (imperial) is up the side

The values attached to the data points are the MPG recorded at that speed

I'd be interested in your opinions and observations..
