Just Tuesday my avg fuel economy went from hovering between 11-12L/100kms to 27-28L/100. It moves a little within those two values, but won't come back down. I know it goes way out of wack when you fill it but it usually comes right back to normal, it's been 3 days now and no change. The problem is my wife is using it around town, so it hasn't really been on the highway or any lengthy drive to see if it resets and/or if the fuel economy is actually that bad. Anyone experience this?
