New Shell FuelSave Diesel?
Has anyone tried the new Shell FuelSave Diesel in their Doopers? I filled up with it on Friday and drove from Nottingham to Birmingham and back. The absolute best mpg I have obtained on the computer is around 68. Imagine my surprise then when it hit an average of 80 during this trip!
With the computer still showing an average of over 75 (as I had covered a few less economical miles since returning home) I refilled at the same garage. I couldn't believe that my ACTUAL mpg was only 62? Now, my computer is usually around 2 to 4 mpg on the optimistic side, but should it really be out by 13mpg! I wondered if this new fuel could somehow "confuse" the computer?
