    The best spped taking into account economy is 56MPH. to acheive this you may be revving the engine more or keep dropping off the accelerator to do this so you woue to have some sort of cruise controlv ha

    the spped limit is the best guide.

  3. Timbo is here says:

    There is not an optimal speed and there is no such chart. Over 50 mph wind resistance is the biggest factor and it increases exponentially with the increase in speed.
    Keep below 50 for the best consumption and in top gear so engine is turning over slowly.
    The consumption will still be influenced by traffic conditions, how fast you accelerate up to speed and how well you anticipate slowing for hold ups etc.
