I'm not sure if there's something faulty with my fuel gauge, but would like some opinions.
I have a 2009 Mazda 3 GT hatchback. From all reports I've read online and in my manual, I have a 55 liter gas tank. This morning, my fuel gauge had the yellow light on indicating low fuel, and the computer showed that I had 20 KM remaining with the amount of fuel I had. At roughly 10.7L / 100KM, that's about 2.14 Liters of fuel remaining in the tank. The low-fuel warning light actually came on when I had about 28KM left (according to the trip computer).
I filled up until the nozzle clicked, then filled a little more slowly until it clicked again (I could hear the gurgling sounds in the tank so it was getting pretty full). The fuel receipt showed that I had put in 44.8 Liters of fuel.
With the 44.8L I put in and the (roughly) 2.2L already in the tank, that brings me to 47L total. Now here's the question: Where are those extra 8 Liters of fuel I should have to bring it up to the 55Liter max? Is it possible that the fuel gauge is not reporting the correct amount of fuel remaining?
I always reset the odometer when I fill up. When I first got the car, I would see the odometer read between 450 - 480KM per tank/fillup. Now when I cram as much fuel in as I can, the odometer shows 380KM until the low fuel light goes on. I'm thinking that the low-fuel warning light is coming on way before it should, but how can I be certain?
I took the car in to the dealership who reported that everything was working within normal parameters, and that the fuel light goes on as a 'reminder' to fill up with gas, but that there is plenty left in the tank (despite the needle being on 'E'). They also said that the 'Kilometers remaining' on the computer is based on the driving habits of the individual person - so although it may say 520km remaining after i just filled the tank, this is based on perfect conditions - no load, no wind, no heater running, basically just the engine sitting on a chassis. I brought the 'Kilometers Remaining' down to 12km (I have to take the highway to work and it's about 15km - I don't want to be stuck!), and filled up again. I was only able to put in 44 liters again.
I'm thinking about buying a 5 liter jerry-can, drive until the thing dies from no gas, and see if that changes anything. Thoughts? Thanks!
