    Fuel Economy - 3.5 V8

    Today I drove from Alice Springs to Tennant Creek (500km) and used 65 litres of unleaded. I was only doing 80 - 90 kph to see how good I could get the economy. This is in a slightly lifted 87 Range Rover Hiline EFI.
    What sort of economy are others getting from their V8s?

    I was pretty happy with that economy. Windows down, no A/C on. No trucks involved!

    The car has been spring lifted and has a homemade 3 inch snorkel. Also fitted with a steel ARB bullbar with drving lights (Hella Bull220) above the top tube. I don't think the wind resistance is anything to brag about!

    I still have to go to Darwin and back to Alice over the course of the next week, so I will keep an eye on the economy throughout the trip. I suspect that sitting on 110 kph will give much worse figures.

    I'm starting to hink about a V8 D2 when I update, the figures I've been hearing lately have been very good. With the price of V8s now it's really worth considering.

    That is really true.. you will probably save more than the difference will be on fuel over quite a while. Just remember that in remote travelling with a
    V8 you have to carry lots more fuel When the going gets harder the V8 will use lots more than the diesel.

    There used to be a Red County at the L/R dealership in Alice owned by one of the mechanics who used to work on the Nor-Force L/R .
    We met up with him at Matoranka and Katherine at the servo , he had a 3.5 v8 and was averaging about 13lt -100km 8O 8O driving a brick at 100km per hour ! He showed me some of his mod's and to say the least i was impressed 8) 8)

    I believe he still has the County and now lives in Daly River .

    Tennant Creek to Katherine, about 700 kms, travelling between 90 to 110 kph, still used about 13.5 litres per hundred. Any faster than that and it tapers off prety quickly.
    I am wondering if the addition of the snorkel is helping my fuel consumption.
