Its physics Tom.... your using more fuel to do more revs and also using more fuel to spin the wheels to counteract the extra wind resistance etc, that's like saying you'd do the same mpg doing 30 as you would doing 60 all day long, guarantee you'd get more sitting at 60. Both Mr Whippy and Poodle have researched as well as tried it themselves, don't think anyone is going to know more about the HDI engine etc than any of the mappers, other than maybe Poodle and Ruan etc. But yeah cba for sitting at 60, 80 if im doing a long run or 70-80 if im not, all depends.
Jack yeah its well worth the £7 a run, so much fun! Cheers!
