Yeh that range is just a load of BS I reckon just like the advertised Mpg u meant to get around town and motorways even. Don’t think they use real life conditions when doing their testing to get them figures!I recently did a 25 mile journey. When I left home I had about 100 miles of diesel available. When I got to my destination I was down to 30. Admittedly I was touching 80mph in places . I marshal at rallies and was running a bit late to get the (free) breakfast before the briefing.
