Re: Mazda 3 2010 fuel gauge fault
On a "full" tank I actually would get at least 600kms (about 50kms per little block of the fuel gauge, on a 1.6L petrol version - lots of diesels here in France). I think at gauge = 0 there should still be about 6-7 liters in the tank (tend to fill it up with about 47-49liters when down to the last little block).
I have another "problem" though, being that the average fuel consumption of the onboard computer is off by half a liter ... upwards. When I picked up the car it read 8.0L; it gradually dropped to 7.4L over the first 4000kms and has now dropped even lower to 7.3L (mixed environment, bit more city trips than highway). The real consumption calculated when filling up the tank however is between 6.9 and 7.0L. I guess the computer needs some time to readjust to the real levels of consumption.
Great car otherwise (not too big a fan of the automatic settings of the ventilation/airco though, prefer manual).
