Gas and milage formula not working out.

Sorry for my English it is not my first language.

I have this file and the column KM/L and R cost per KM is not giving me the correct info.

I not always filling my car up with gas, as the prices changes quit here, so now it does not work the formula out right.

I put in the Liters put in, and when I full up again, then I put in the Odometer Reading
