Official Fuel Economy Thread (formerly Highway economy).

...And you must be living and driving in the area without the hills, cause the hills would kill the fuel economy. I can see figures as low as 4.6 average on the MFD when I arrive in the city at 9 PM and when I get almost all green at the traffic lights. But my wife drives Tig 99% of the time to work and to the shops, we live at the hills and average now is 7.0L (MFD) at 2350km. I'm quite happy with that.

actually that run was not that flat, quite a few hills on the hwy up to southern QLD from norther nsw. I agree a very up and down route doesn't help, though again it depends a fair bit on we drive/approach it. What really kills it is a net ascent and likewise a net descent does wonders for it.

and yes of course our long term av is much higher, my post was to show it could be done, as an earlier poster didn't think it was possible. It was to also show that even the TSI's are quite economical when driven so.

If I was driving our TSI Tig I would say our long term av would be somewhere in the 7's, but Mrs drives it most of the time and its more around 8.0-8.5, which is still good considering it does a lot of short trips around town.

I tried to drive to work 'economically' this morning & as i consider myself a bit of a motoring enthusiast, i must say, it drove me crazy trying to change up through gears at 2000rpm.....
The ''fun-factor's'' gotta be worth more than $2.80/100km, IMO. Will happily sit on a long term av' of mid to high 9's.

Cheap thrills!
It can be driven economically but giving it the beans with the 4Mo system and Stage 2 is too much fun to play the economy game all the time.

Taking the Tig for its first big drive over easter. Heading to Melbourne from Sydney. Anyone reckon I will do the 860km on a single tank? Not keen on driving slow for economy.
It will require an average of 7l/100km - surely should be achievable in my Tdi auto...won't be heavily loaded, just me and the dog.
My old 93 camry did 8s on the highway so if I don't get 7l/100 from my diesel then I'll not be happy!

860 for a tank would be right on the limit for a petrol if you are driving in a usual manner i would say.
For a diesel it should be easily doable.
Just note that the air con will kill fuel economy as does going over 100km/h.

Mine will return 6.8 at 90km/h on the highway

That's great, Team V, for the performance capabilities of yours!! Do you update or track your 'long' average, what's that on?
I'm still (13000k's) sitting on a long term av of 9.0 in my stock 125. Semi-spirited city driving.

Long average is on 9.5 but i have been giving it the beans lately.
If i drive "sensibly" i can get the trip average to be in the 8's around town.

I try not to reset the total average (fuel economy 2) so i get a long term view of my use.

Not sure if you've noticed this on yours, but my "2" records all reset when the driving time hit 100 hours. I am pretty sure I didn't reset it myself because one day I looked and it was on 99hrs.xxm and the next day I looked it was back to 2hrs.xxm my average fuel had gone from 8.5 to over 10...I only touch the reset when I refuel and I hadn't refuelled.

[jimbomort]

hmmm not sure about the reset but I will look at ours

our long term is on about 7.8, though in the first 12 months it would have been more like mid 8's, so long long term would be more like low 8's. We do lots of short trips etc, and some heavy traffic, but also lots of regional driving. My wife drives ours most of the time, if just on hers would be mid 8's, if just on mine would be low 7's. I enjoy giving it the stick occassionally, but I drive economically most of the time. We dont use air con much, ours is a manual and I generally keep it to a 100 on the hwy, so most of my trips, even through town are in the 6's and low 7's.

I'm not sure if this is the right spot but rather then starting a new topic I thought it would be appropriate to ask in this thread.

When collecting a new VW specifically a 147 Tig from a dealer should it come with a full tank of petrol. Is it common practice for VW to fill it with 95 or 98 octane fuel?

Lastly, I know this is a topic of great debate but what are people's opinions about the best petrol for the Tig? I was thinking of using BP Ultimate.
