Thread: New Hilux Fuel Consumption

Cool. For an accurate measurement you need to be topping it up to the point at which you can see the fuel and it is not dropping down into the tank. Then reset your odometer. Then at the next fill you do exactly the same. Only then will you get an accurate fuel consumption calculation.

With an OBD2 scanner like the Scangauge, to calibrate the fuel consumption you do the above three or four times, adjusting the scanner’s calculated consumption to the actual amount of fuel you put in the vehicle. Once it is calibrated it is incredibly accurate - I have 140L fuel tank on my Hilux and I have run it close to empty in outback conditions (>1200km) and the scanner has predicted the refill amount to the nearest litre. This gives you all sorts of useful range statistics.

As we have discussed the actual fuel consumption as properly measured has always been less than on the dash display.

Completely irrelevant for what you want to do but interesting nonetheless. Glad the situation appears to be as predicted.
