    Trip Comp consistantly 16-20% under actual consumption.

    Any reason behind this? It's literally ****ing useless.

    Check my fuel log, updated my last three with readout mileage.

    I'm comparing the trip computer to actual consumption?

    Have you compared the odometer to what a GPS indicates?

    Is the Micra connecting to a GPS somehow?

    Would the Micra not use the same information to give me odometer readings as it does my fuel economy?

    I expect that it does, but I'm just looking for anything that might account for such a large discrepancy. I own a 2014 CUBE, and a 2018 NOTE and both of their readouts are off, but not by that much.
    I put slightly larger tyres on the CUBE (65R instead of 60R) and the calculated mileage went down slightly. In reality the consumption improved when I considered the actual distance covered.

    I don't blame you for despising the economy; you sure put a lot of miles on it.

    No, it's just using a sensor in the transmission.

    Tomcj2 was just asking if you've checked your odometer accuracy.

    Are you resetting the fuel economy gauge at each fill-up and filling the tank to the top each time?
