Normal fuel consumption for XR6?
What fuel consumption should I get for my 2005 BA Falcon XR6 sedan?
When I bought it three years ago it was using 11L/100km, but after cleaning the plugs, a diagnostic computer check that showed nothing major, an injector service, and replacing the exhaust sensor and cleaning throttle it was showing 13.2L/100km.
Now, a week later on the dash it says I'm using 13.3L/100km? Do you know what's causing the problem?
I always fill up with 98 fuel, as it pings on 91 fuel.

Ford's official fuel consumption was 11.3L/100km combined, now that's a blend of city type driving and country driving.
Given that, if you're driving mostly in the city I would expect you to get a little more than 11.3L/100km, so maybe it's not too far from what you should be getting.
It shouldn't be pinging on 91-octane fuel, and I'm guessing the engine is carboned-up.
I would give it a solid blast down the highway and see if you can blow the carbon out. You could also try an engine cleaner in the fuel.
