  1. MPG Optimum Speed for Fuel Efficiency

    Engines and Transmission (8G)
    I have a daily commute of 70mi between Manchester and Telford. This works out at about 35,000mi a year in my 2.2 i-CTDi diesel. I've heard various thoughts on fuel economy, but does anyone have a view on the optimum speed for fuel efficiency?
