    D4 fuel tank capacity with empty indication

    Hi All,

    I have been monitoring fuel use, indication and refill levels getting ready for a cape trip. The D4 diesel has an 82 litre tank. As indicated I have ~100km of fuel left.

    When filled it topped at 65 litres, therefore there was 17 litres left in the tank. My ave fuel use is 8.5ltr/km and it has been over 500km, therefore the computed distance should be around 200km. Is this typical?

    Setting this aside, I never allow the tank to empty, however is there a threshold alarm, what qty of fuel is left when the alarm is flagged.

    Regards

    Gerald

    I am interested in how low can you go as well. I have on 2 ocassions now run down to 20 - 30kms to go on the computer. On both ocassoons I managed to get 74 l in there. I was carrying a jerry can so could have easily added 20l if needed. I have heard it is not god to run out of fuel in modern engines especially a direct injection diesel. Has Anyone experience of consequence of running it dry?

    Paul,

    Two things with modern diesels, one is breaking the system if it runs dry, and the second thing is keeping the diesel cool, the low pressure return from the rail needs cooling to ensure fuel density is maintained for optimum spray.

    Anyway, I was told this by a 40 year experienced truck driver.

    I have a D3, and I have been down to 0 km left on the computer and got 81L into the tank. I'm assuming the fuel system is similar.

    Fuel tank states 82L, but less pump & both senders, means approx 78L.

    Just did Adelaide on the weekend from Melbourne, squeezed in 76.4L & the warning was saying 30Km's until empty.

    Wasn't nice in the drivers seat.... ;-)

    So, topping it up when you know that another fuel stop is a long stretch away how much can you top it up to? I generally fill to the second "click" on the bowser.

    I occasionally (once when heading down the Connie Sue to Annie Beadell) filled the Defender right up but I suspect most of the extra beyond click 2 ended up on the track.

    What's the limit in owners' experience? Can you fill it to, say, you can see the fuel near the lip?
