My car drinks more fuel than a Russian peasant drinks vodka

No, tuning to fix problems is a bandaid fix that treats the symptoms and not the underlying causes. Car should always be running correctly before tuning.

What is your average speed from the trip computer?

I think it was in the 20's or 30's km/h? can't remember. I'll have to look tomorrow to get an accurate reading.

What sort of driving do you do? Is it stop start all the time? Motor Way? Country? or a mix.

Do you do an actual check on the consumption by filling right up and calculating the actual fuel used vs the actual km?

How do you drive? Are you on the limiter every chance you get dragging off every other motorist on the road at the Traffic Light GP?

For your consumption I'd do the 02 sensors first as they are really cheap for genuine ones off EBay or Summit racing, well cheap compared to a weeks fuel!

From there you can look at the other options above.

My car is getting around 11.5 - 12.0 driving like a normal person but was getting around 13.5 driving like I stole it, however that is 90% motorway driving

Mix of stop/start, motorway.

No manual calculations, I just what go off what's on the computer/gauge.

I honestly don't give it at all. I barely take her past 3.5k rpm. There might be the off time i open up the throttle but I honestly barely ever.

i drove about 100km today and half a tank of petrol is gone!

are you using crap ethanol fuel or petrol

It will be the 02 sensors, the air temp sensor or a **** tune if its been tuned before, that's pretty much it unless a fuel injectors leaking or something else damage wise.

Most likely its the 02 sensors.

My SS has alot of goodies and still on highway i can get 7.2l per hundred and cruising around is like 14l per hundred or so, giving it the beans is another story all together

I am wondering if the fuel gauge is playing up..... how much actual fuel is going in on each fillup OP?

sometimes you need to re-iterate stuff.

Yep I would go with replacing the Oxy sensors aswel.

I replaced them both in my VT and fuel economy improved.
