    Defender Td5 and fuel consumption

    Given fuel prices and the amount of kms I do my economy on the Td5 defender is one of it's best features for me. Wether city/ open road, towing I always seem to get 10l/100km on the mark.

    That was until I just did 5000km over Easter were 12l/100km was the best i got nad it went up to 14 on open drives.

    Now the major differences are;

    Fitted a Safari Snorkel prior to leaving

    Borrowed a ARB 3/4 roof rack

    Now before you say weight, I went over the public weigh bridge and had bugger all than normal, swag and camp oven the heaviest things. I also sat on 100km/hour, were I normally do 110km on trips.

    So it must be the roof rack. Amazed it would make that much difference. Given that it was borrowed to get the spare off the back door I reckon removal and a spare wheel carrier will pay for itself in no time.

    I would be interested in what others are getting in economy as stuff I have read on the forum seems to vary greatly. Also if others have had the same with racks.

    Defender econmoy.

    Hi Dages.
    I get around 11 kpl but most of my driving is short trips to and from work where it hardly even warms up.
    The worst I've ever got was about 6kpl and that was dragging a van weighing 1.5t and into a strong headwind on the road between Hedland and Broome last year.
    I've also got a roof rack but have never checked figures without it.

    If I had room I'd devise a system whereby I could lift it off and leave it hanging up at the ceiling where it would be ready to drop on for the next trip.
    I've just sold the van and am going to a camper trailer mostly so we can go further off road but as an additional unintended benefit we will get better economy.
    With prices which might increase much more and with no real end in sight I think this may well be worth it.
    Happy LR ing.
    Alan.

    Mine averages 10L / 100 klms, until I fitted a 1/2 rack (see pic), and it went up to 12 litres / 100 klms. Rack is now off and stored till required. Weight is not the issue, I believe it is the wind drag. Quieter without it also.

    Gotta agree with everything said with respect to drag versus weight. The other factor is speed. Go over 110-120kmh and everything goes out the window.....literally!

    Kimba has been remapped and the fuel consumption is pretty much the same. On average (with a roof rack and not loaded) we get 11l/100km everywhere.

    Load the rack, with the swag and box and we go up to 12s.

    Travelling around Oz, fully loaded, pulling a 1.5 tonne trailer we averaged mid 13s over 51,000kms. The worst was 14+ with the trailer in sand. Trailer + vehicle was over 4 tonne.

    I have an EezyAwn rooftop tent up front and an ARB half rack behind that. I consistently get 11L/100km on the freeway - on which I do a steady 110kmh. Our trips to Cooma also contain a few hundred kays of 100kmh roads, sothat brings the average down.

    I will take the tent off one day to see what consumption I get, but it's a pain in the backside to keep taking it down and putting it back up all the time. I like to have it there permanently so that we always have somewhere to sleep if need be.

    Yeah I agree that weight seems to make little difference. Will take the rack off this weekend to test.

    I am building on our block some 400km from where I currently live. I regularly take a tonne down on a trailer and drive back empty. This towing seems to make little difference to fuel sitting on 90 to 100km.

    And is one reason why I am a very happy as a Td5 owner, given that it also drives even better with that weight.

    Have been told that a snorkel will reduce consumpltion, don't really think it would be large enough to notice.

    A good wind deflector will cut down on the drag, most racks have a rather blunt front on them.

    I have always had a full roof basket rack LR(AR, and get about 10.5l/100 on average, but have noticed this go up to almost 13, when the rack is loaded. I too thought a deflector may help, especially as I am hading off on a 10K plus trip in July - I figured it may be worth while.

    Anyone got any ideas on a decent deflector, or where I could pick one up in SA?
