Lately my Gas gauge say 1/4 tank left. Computer Say 0 kilometers to empty. Who is correct?
Or, how to "reset" gas calibration?

I would fill the fuel tank and determine how many gallons it takes - that will answer the question on zero KM to empty, or 1/4 tank left.

I don’t know how to reset the gas calibration.
