My car has a mph speedo face sticker over the kph logo and the speed goes up in mph with the markings on the clocks.

 

But i think my milage is going up in km, is that possible?

i believe so.... mines seems the same

If it is then that would be very cool.

 

I best check my milometer on the way to work

Yep, mine was fitted with a mph clock into a km/h housing leaving the original odometer in place, so I still have a km/h reading on the odometer and trip meters

I converted mine and it now runs up in miles - both the speed and the odometer. I have had to make a note of the exact mileage when i converted so i can work out the correct mileage when needed. Got about 100k in KM's and 7k in miles lol.
