Mazda BT-50 2014: High fuel consumption

Asked by William Steel

My Mazda BT-50's fuel consumption has been steadily increasing over time. I am now up to 25,600 km and the vehicle is using up to 11 L/100 km without any load. The last time I took it to the dealer the service manager said that they had cleaned something or other. I topped up the tank, reset the trip computer and drove to Sunshine Coast, a distance of about 190 km. When I got there the trip computer was reading 8.8 L/100 km. I got back in the car the next day and drove back along the same road, the Bruce Highway, and it was reading 9.4 L/10 km. It's now up to 10.2 L/100 km. It's actually higher when measured at the pump than what the trip computer says. Any suggestions where I could get this looked at properly?

The fuel consumption figures you have supplied don't seem to be too far off what Mazda claims it should do. Mazda claims an urban fuel consumption of 11.76 L/100 km, which would appear to be in line with your 11.0 L/100 km, and a combined figure of 8.9 L/100 km, which would seem to be in line with your 8.8 L/100 km. The type of driving has an enormous impact on fuel consumption and I suspect that's the main factor in what you are seeing. If you want to have the vehicle checked take it to a diesel mechanic.
