garypark Posted December 25, 2012 Report Share Posted December 25, 2012 Somewhere in one of the multitude of computers that run the C-Max there must be one that know very accurately how much gas it uses each time an injector squirts. Otherwise the car would not run well. My guess is they only keep an truncated version of that squirt volume for the other "less essential" uses of that data such as displaying the milage to the driver. Due to all the various laws about falsifying an odometer reading they dare not truncate the miles value as it is passed around. So the MPG displayed will be a little high for each squirt-loss. The error should be linear with distance. Quote Link to comment Share on other sites More sharing options...
