Whats your average fuel consumption. I get 350-400km city and easily 550-650km highway.
About 500 k's mixed city and highway.
250km ish / tank, V6 5 speed, though that is mountain runs etc, haven't had it 5speed long enough to see what its like normal driving. I hope its alot better! $200 fuel in four days is not cool.
VS SII S Pack V6 5sp Manual that I just sold a month ago used to use 8lt/100km on the highway. Thats 12.5km per litre. Meticulously serviced by me especially oil and filter and air filter every 5,000kms plus tyres aligned and balanced and pressures checked weekly and kept at 34psi all round on factory 15" mags.
mine is stock VR it use to use a full tank (68L) in about 600-650kms, now im lucky to get 400km out of it, i still drive it the same way (never foot to floor, never over 3000rpm), and it is mostly highway kms that i do
Mostly highway km's and only about 400kms....I wouldn't be happy with that. My VS had done well over 200,000kms when I sold it and I was getting 700kms or more on just highway runs. Around town with very short trips I would get 400-450kms approx.
I would get a diagnosis done via auto electrician or even get a dyno tuner to check mixtures. The cost of getting this done would be well worth it especially if you could get back to well over 600kms+ to a tank like you should be getting.
Could be a number of issues. Do all the normal servicing of filters and oil, then do spark leads and plugs if not done for a while, don't forget fuel filter, check tyre pressures. Stock tyres like 15" should be minimum 34psi, check exhaust for leaks at engine or through system and even catalytic converter may need replacing if its still factory. So many things to do, but its worth it in the long run.
it has done over 300,000 kms but ive had cars with higher kms and they still got alot more kms out of the tank. about a week after it started drinking the fuel we replaced the back resinator with a luckey mufler cos the resinator was clogged, and one of the bolts on the flange snapped but i dont really think this could of effected it because it started using more fuel before then, i should be replacing the bolt in one the next couple of weekends
I'm only getting 400km with mixed driving which is about 20% down on a years or so ago. I figure it's the oxygen sensors as they are original (210,000km). The car has heaps of power and runs like a Swiss watch so I'm not too worried....the truth probably is I'm too tight to spend the $$$.
Thats like playing with a double edged sword. Your economy is 20% down but you don't want to spend the money on an oxygen sensor. Wouldn't you be better to spend the money on the oxygen sensors, then get the rewards very soon in the future and continue to get the rewards due to better fuel economy???
400km on 50 litres city , 650+ on pure highway.
Hako , isn't injecta-carb just down the road from you ?
OK - OK.....new O2 sensors I will buy.....20% is $6 per week on my fuel bill so that's over $300 per year...probably more like $500 taking into account long trips like next week I drive to Townsville and return.
So, I've ordered and paid (it hurt) for 2 new ones on Ebay - $58 ea plus $7 postage - gen Delphi 4 wires.
I guess I can't take good advice eh!
And I'll post on the improvement.
Thanks.'
ps...that 400km is figured for 63 litres...that's about 16 l/100km...stone the crows.

i get between 350 to 450km a tank and its about half half with the city and highway driving
in all city driving very consistently get 400-420k, its a wagon so its a 68L tank, but whenever i fill its only just over 60L
thats manual and never taking it above 3000rpm
Over 200K, V6 Auto VSii and I get about 700km to the tank, mixed driving.
I always keep the oil clean, but I wouldn't say it is regularly serviced.
The VS's SHOULD be really great on fuel eco.
i have a vs SIII ute with vt motor and only getting 380-420kms per tank city driving and mostly around 1500 - 1700rpm
