Hi there,
Using http://www.spritmonitor.de/en/ I collected my "brim-to-brim" re-fuelling data for analysis. The tool allows to calculate real fuel economy judging by real mileage and amount of fuel used, so gives quite precise figures.
Thus, I found out that my instrument cluster MPG figures are about 4-5% optimistic. E.g. 25 mpg real figure is 26.2 mpg by display.
My previous car, a BMW 528i, had a special engineering mode in its OBC (On-Board Computer). You could put MPG correction factor there and I managed to get the OBC to display very precise figures (down to 1% give or take).
I wonder if I can do the same on my Mercedes C180K '09?
Thank you for reading this.
