What Fuel to use - Super Unleaded or Standard - does it matter?

Steve:
The mpg is not poor it is bloody awful!
This is the first time any of my cars has drunk petrol as if it was going out of flipping fashion.
Lets hope it improves. Otherwise, it is back to the dealer for a tweak-a-boo!

That does seem very low mpg? Maybe the ecu needs to checked by the dealer, they have to map it again? It as been known befor!

Thanks.
Will contact service department if it does not improve soon.
It is a pain in the wallet.

Getting lousy fuel consumption.
Using high octane petrol. 75 miles of town driving so far with a full fat diet of traffic jams.
Trip computer registering average 13.9 mpg! Not happy.
Mileage so far: 315 miles.

If you're stuck in London traffic all the time, I wouldn't be surprised at getting less than 20mpg. Get out of the city this weekend and give it a proper long run, you'll see a vast improvement.

Mine's only done <800 miles so far but even in stop start town traffic mixed in with a couple of short motorway drives the lowest I've dropped down to is 29 mpg on Shell's finest

Mines at ~114 miles :embarassed: and im getting around 36mpg to work and 28ish back (4.30pm rush hour) according to the computer but computers lie.

Both my mk5 and mk6 had an improvement in mpg around the 1500mile mark (not exact as it may be a km setting).

There is something in the ECU that changes around this mileage.
Also the engine is bedded in and working better.

I've just come back from a 300 mile round trip (mostly on the M1 plodding along at 75mph) and averaged 39 mpg.. Also have now crept over the 1k miles so will see how the mpg fairs going forward now that she's loosening up a bit

Typo surely, I'm sure you meant 70mph.
Fo those interested I can confirm the mpg is around the published 10% up on the mk5.

Much happier today.
Fuel consumption much improved.
Now approximately 25 mpg in traffic.
