I was wondering if the R having an extra 5L tank capacity made it behave differently. In all honesty, i'd expect the 3 cars to be calibrated slightly differently on remaining fuel, so they gave a common number of miles remaining on the low fuel warning.
Anyway, as predicted, 100 yards into my journey to meet up with Chris (mcmaddy), the light came on - 30 miles left on the range. I got down past Sunderland and Chris set to work with the changes:-
Soundaktor down to 30%. It's now sounding in Race mode like 100% is for Normal mode. I prefer it this way - enhancing the natural engine sound rather than drowning it out completely. There's something a little unnerving about not being able to hear what is going on with the engine as you're driving it (especially during the running in period).
Coming home lights activating automatically, without a high beam flash.
Volume (Gallons) required to refill.
Had a quick blast up one junction of the A19 and back again with Chris, just to try the soundaktor out at it's new setting.
Then I filled up on the way home, around 10 miles into "0 miles". The car took 53.32L (11.64 Gallons) to do 321.2 miles = 27.6mpg for its first fill - with Shell Nitro + (computer read 28.9mpg "since fill").
Feeling a little wary of having dipped 10 miles into "0 miles", I decided not to chance driving on to the nearest Shell garage, so thought i'd try out Esso Supreme and see what that does for me - might not be a fair comparison, as next week in my new job, my commute is going to double,so i'm expecting slightly better mpg if there are no extra opportunities to put my foot down, and the further running in of the car might also take effect.
