Sorry if I asked for too much… just looking for some evidence to back up a statement you just made from a training manual. If you (and the manual) were right, then taking my car out of gear would always make the gauge “shoot past 50”, right? That is not the case. It appears to me that the computer is doing a fine job at calculating the mpg so before you make statements be sure you can back yourself up more than just saying “i read it in a training manual”.
