Most of those speedos, in the instructions, have a setting for Miles...Kilometers is usually the default value until you access the settings and set it accordingly...DAMIENIt's the stupid speedometer I bought. Didn't realize it was kilometers. It went 52 kilometers per the two liter tank. That's approx 60 mpg.
Ps...You will usually get less mileage per gallon during the break-in period.
