I've never gotten my car below 9.9l/100km I think. 1 Link to comment Share on other sites More sharing options...

Makes me wonder how the average is calculated in FGs. Link to comment Share on other sites More sharing options...

Going up and down hills moves the float in the tank. Surely with EFI it "knows" how much fuel gets squirted in for each combustion cycle (4 bar pressure, pulsewidth, injector flow characteristics), and the wheel speed sensor combined with the programmed tyre diameter allows the distance calculation to take place. Compare the two and you get fuel per distance. Interestingly I found before custom tuning the car reported a higher than actual fuel use. After custom tune it reported a lower than actual use. About 0.5 to 1L/100 either way. As said the only way worth checking is to fill it right up, drive and fill it right up again and record odometer before you head off. I used to write it on the fuel docket. Haven't bothered for years though. I just reset Trip A each fill up and take a bit of a look at the fuel needle as I'm driving around, say at 3/4, 1/2 and 1/4 (if I let it get that low) then guesstimate. Trip B records distance since last oil change Link to comment Share on other sites More sharing options...

It was actually down to 8.4 l / 100km as I arrived into Belair Link to comment Share on other sites More sharing options...
