Pathfinder power

We recently said goodbye to the Outlander and hello to a Nissan Pathfinder 4.0 V6 Aventura. It's currently being converted to LPG. I plan to write a review of the last 12 months and then detail the conversion of the Pathfinder.

How to rate our efficiency

An interesting discussion started today following on from a tweet from @bobbyllew (of scrapheap, red dwarf and Carpool fame) on the best method to demostrate just how cheap it was for him to run is Mitsubishi iMeiv. MPG doesn't apply unless you make some strange calculation of power so he stumped for Cost per 100 miles driven. I suggested Pence per mile, a figure I often use when comparing the relative costs of running a vehicle. The subsequent twitter stream made interesting reading with many pro and counter arguments.
The bottom line is that you're trying to compare apples and oranges between Electric and fossil fuelled cars. The costs per mile is a relative figure but is impacted by the changing costs of the respecting 'fuel' and so it's merit as a published figure is useful but time limited.
Perhaps we need a traffic light system to be introduced.
