I have a LR Discovery 2 and have been using fuelly since 2017. The currency thing is a bit tricky I think. The numbers don't add up after changing the vehicle's location. Are there any guides or cases I could read?
I take it you have imported the car from Norway and instead of inputting the fuel cost on NOK you are now using GBP. Problem with Fuelly is it doesn't use a currency per se, you just use your local currency, so you cannot retro convert. Easiest way to keep numbers going is to convert GBP back to NOK before putting into Fuelly.
