How to Measure Fuel Consumption

• Fill the petrol in the fuel tank until gas vapours can be seen in the fuel inlet pipe.
  
  
• Once the gas vapours can be seen in the fuel inlet pipe wait for about 20~30 seconds and if possible wait for more than a minute for more accurate calculation.
  
  
• Do not shake the vehicle's body.
  
  
• As soon as the gas vapours sinks add more petrol till the gas surface is visible once again.
  
  
• Initialize the trip meter to zero at the petrol pump.
  
  
• Drive the vehicle till the fuel gauge needle reaches the 'E' Position. Ensure that no petrol has been added in between.
  
  
• Repeat steps 1~4 again.
  
  
• Read the petrol quantity from the pump.
  
  
• Read the mileage from the trip meter.
  
  
• Calculate the fuel consumption. (Trip meter mileage - Petrol quantity)
  
  
• After calculating the fuel consumption, once again initialize the trip meter to zero.
  
  
• Repeat the above procedure at least 5~6 times.
  
  
• Calculate the average fuel consumption.
