    Mazda BT-50 2009: High fuel consumption

    Mazda Mazda Advice Mazda BT-50 Mazda BT-50 Advice Mazda BT-50 2009
    I believe my 2009 Mazda BT-50 dual-cab 4WD with uses excessive fuel. It averages 12 L/100 km in combined use and 11 L/100 km in Highway use with no load and sticking to the speed limits. I have complained to my Mazda dealer and at first they told me to wait till the vehicle has done at least 10,000 km. It was still using the same amount of fuel at 15,000 km so again I complained and they checked the fuel system, but could find no fault. I wrote to Mazda, but they gave me the brush-off by saying the dealer had checked the fuel system and found no fault. A neighbour has an almost identical BT-50 and his vehicle uses less than 10 L/100 km. In desperation I had him drive my vehicle for a period, and the best he could do was 11.9 L/ 100 km. I again approached my dealer and he suggested I do another 8000 km and see if it gets any better. What could be the reason?

    As Mazda pointed out to you the fuel consumption figures they publish are the results of laboratory tests mandated by the government. Every carmaker has to do the test and publish the results on a sticker on the windscreen of the car. As such it shouldn't be taken as fact that you will get the same figures when you drive the car in real life. The figures are given as a guide and for you to use when comparing one vehicle with another. There are many things that affect fuel economy, so you need to check everything that might cause your consumption to be higher and make sure you are doing everything you can in your driving environment to minimize your fuel consumption. Having done all of that it does seem that your vehicle is using too much fuel, as you say. I would engage your dealer and ask that he set up a fuel consumption test that measures the actual amount of fuel you are using so that both you and the dealer are in agreement about the fuel being used. You will then have a common basis on which to discuss what action you and the dealer could take going forward.
