Fuel gauge calibration
The process of calibrating the fuel tank gauges is complicated and requires precise measurement of the fuel added. The factory calibration is close but not exact, which led me to generate a chart of the Actual versus Gauge fuel levels. This was completed by adding 20 liters at a time and doing a linear progression to determine the numbers for each 10 liters in the tanks.
