    Gen2 fuel consumption
    Answered by Graham Smith · 12 May 2011

    Proton's official consumption for the Gen 2 GXR is 7.9 L/100 km average, but 6.2 L/100 km on highway and 10.8 L/100 km on urban use. The latter suggests your car is not far away from the company's claims. Normally the trip computer is more accurate because it measures the fuel being injected into the engine, whereas the old fashioned method of fill-to-fill measurement has plenty of room for error. But in your case there is reason to suspect the trip computer, even more so when you've been told there's a dealer bulletin to check for fuel consumption. That suggests there is something wrong. Take it to the dealer and have it checked as has been recommended.
