    Hey ppls just wondering what sort of kms I should be getting from my VR SS Auto. I only get roughly about 280kms a tank on premium around the city, is that about standard? The car is stock, exhaust and all.

    Hey mate thats pretty bad, you should be getting around 350kms or up from a full tank, check your ignition system, spark plugs, leads, etc. I know theres other things to check as well but im not sure what they are, a good service might help.

    if you havent already done it go thru and replace ya leads, plugs, dizzy cap & rotor button, air filter, and fuel filter.

    those are usually the biggest affectors of fuel usage and are not very expensive but if it hasnt helped much after that i would say your injectors are next

    Or the mostly likely failure on the V8s is the fuel regulator

    Shouldn't you be able to get 500-600km out of a long-range tank?

    Not so easy for these guys Mortus, most people weigh 50 kilos more than us. That makes for some heavy feet

    in this order:

    0) pump tyres up to 38psi
    1) oil
    2) oil filter
    3) air filter (if it needs changing, check it)
    4) fuel filter
    5) spark plugs
    6) rotor button
    7) dizzy cap
    8) oxy sensor
    9) spark leads (if they need it, check the resistance against factory specs)

    then see how you're going for money :p

    I drove my VP a couple hundred ks today and got about 10L/100 maybe a little better than that. So it's doing ok at the moment. That was without lean cruise

    The VR SS have an 80 liter tank I was told, on empty when I fill up it only takes about 55 liters I guess my fuel gauge is prolly out?

    mate your fuel gauge won't affect how much petrol you can fit in the tank.

    BUT if what you mean is that your gauge reads empty and your car only takes 55ltrs then the only way to really find out is to run it out i guess. Not good for the pump but i don't have another idea.

    HOWEVER based on those figures - 55 ltrs to about 300kms your fuel use is still bad.

    Well since my wifes driving my VP to work lately I'd thought I'd do an experiment, since it's probably in perfect running order (you would assume so from the times it runs) I thought it would be good to see how far you can go on a tank in a 5 litre that's running well. She filled the tank up the other day, from just under the last little notch on the gauge it took 65 litres and so far is at exactly half tank and used traveled 320 or 330 km's (I forgot but one or the other). I'm not sure if the second half of the tank will go the same distance or not but that's where its at right now just on my normal VN based tune no lean cruise or anything fancy, it's looking like it'll go at least 600 ks on the 65 litres. If she's still driving it next tank I'll try and increase it 10% or so. This is all about 70% highway and 30% town with 4 cold starts a day

    The car had an full engine rebuild in 2002 maybe they never got it tuned right? I just took it up Tassienats and got 330kms with about a third of a tank left but I was sitting on 150 160kms/h most of the way and about 2 1/2 grand that still seems a bit much for highway driving hey.
    Getting a service on Thursday then might look into getting it Dyno tuned soon as I can afford it.

    VR maloo
    I drive my vr maloo like its stolen- tricked auto box exhaust with holes all through the mufflers not even got the hsv cold air box on atm- i get roughly 13l every 100km city bout 9.5-10.5 country so bout 11-11.5 average a week i do 90kms to work 6 days a week and use roughly over 100l of fuel with running about on a sunday / shop runs etc.
    hope this was helpful comparison.
    Oh btw 469000kms orignal motor - used and abused by myself and driven 4 states of australia for work including bad, bad dirt roads.
