Is there anything I can do about my inaccurate fuel gauge? Today it was at the bottom of the red zone, and I put in 9.5 litres and it went up to half a tank, but the tank is 42 litres.
I have an OPCOM device, but I don't know how to read the actual amount of fuel in the tank.
Is there anything I can do to fix this?
