Fuel Consumption

[NickZ]

GTI can officially run on RON95, but there is a big difference in economy and performance when on 98. For a lot of cars the difference is negligible, but for some reason it seems to impact our 1.8T a lot more!

On the end of your wiper stalk (the right one) there is a couple of buttons. Press them up and down and in the display you will see all the functions, including fuel consumption. I am guessing you didn't realise the GTI has a trip computer!

yeah i did i, i mustve have missed it when i was reading the manual. I eventually ending up finding it so now its all good

400-450 is my max, that's mostly highway a lil/lot above 110 However I'm on the M4 a lot so that's always a car park. Normally round 7.5-8.5l/100km.

Lots of surprises here bout petrol consumption. I could never get more then 600km from a tank, even 500km would only be drives to Canberra and back. Ben_GTI before I saw your name I thought for sure you were in a diesel.

As you know the consumption depends on lots of factors...
1) wind / weight (passengers) / window being open or closed / air conditionining on / tow bar / high way / city driving....

I hear that if you are going above 90km/h, it's more economical to have airconditioning on at 1, rather than full window open for air resistance reasons.

Tow bar is surprisingly heavier than you guys think..

Highway / city driving -> should really mean what sort of rev you are sitting on at constant speed. For example if you are doing 70km/h on 5th gear, you will probably get the best mileage!

I do lots of city and some high way, and I got around 470km with quarter tank left. And after filling with not the best biofuel from Gull I've done 200km and it's just used a quarter of the tank! this is 50% motorway 50% city.

I find the car very economical, I often get 12km/litres or more...

If I drive up to the Sunshine Coast from Bris and back again ... it takes less than 1/2 a tank and a week to use up the remainder of a tank around town. In that situation, I usually achieve approx. 600ks/tank. (Conservative driving? I don't think so. )

In steady freeway driving I average 6.6-7.1l/100km so I get about 600km out of a tank. (before reserve light turns on)

In normal commuting I average 9.0l/100km for 450km (before reserve light turns on)

In aggressive use mode I have seen 17l/100km and have had a few tanks empty at 300-350km.

So it all depends on the weigth of you right foot ....

My car has only done 16000km and fuel consumption has been pretty steady since new.

I average about 450 a tank of BP Ultimate.

Only got 220km out of a tank on my last track day haha.

Hoyhoy.
Well I might be 1 of the oldest on this site but still young at heart, because I'm lucky to get 400KM's before the light comes on.
P.S. I do have some fun though.

Don't want to take this thread too far from the main point, but those of you that only use the one kind of fuel, can I ask why? Is it that you had a bad experience with a type of fuel? Or that your have a petrol card for that brand? I can see those being the only reasons, there is know way your bum dyno is that good to tell differences in possible power between different petrol brands. Neither do I believe you get more km from one brand to make it worth while searching around for the type you must have.

Don't want to start an argument, just interested in peoples thoughts on the matter.

I've seen a lot of 'fuel consumption' threads on various forums, and my only request is this: please, please measure fuel consumption in terms of litres/100km (calculated by litres purchased divided by odo at fill minus odo at last fill), not in terms of 'how much per tank'. There are just too many variables in 'the tank range' approach...eg, how empty was it at last fill; what was the temperature; was the same pump used...etc n:

You'd be amazed how small variations such as these can have significant effects on so-called range measures of fuel economy but if you calculate in terms of L/100k, it will be quite consistent relative to driving style.

FWIW, my long term average fuel economy, over 30,000ks is 8.1L/100k.

I always use 98 (the odd tank of Vortex Racing) and have not discovered any discernible economy or power difference in any brand.
