On motorway and without cruise I can easily get 200miles to a half tank. I think that works out about 29mpg. seems to be getting better the more miles I put on....as does the perfromance.

17 around town with a bit of booting, 22 on fun A roads, 23-25 om M-way.... boring

I have just done 92miles from full and the gauge has moved a tiny bit off the max. Range currently showing 380miles + 92 I have just done = excellent.

In fairness when I filled up I kept the G Spot button pressed.

Unless you have had a re-map, specifically for 102 RON, then you wont actually gain any benefit from using BP 102.

BP Ultimate is 97 RON, not 98. Futhermore, BP Ultimate has been proven, in two independent tests, to be worse than Tesco 99 (which is also the official fuel of the British Rally Championship) and also the now obsolete Shell Optimax (98 RON).

BTW, I started with about 24mpg, whilst running it in. But as I open her up, it's starting to drop - about 18mpg ATM.

Now I am confused?

I thought we were supposed to run these on the best fuel we could, but I read your comments as this is not the case?

Please put this into plain english, for me at least.

Thanks

The ECU has been programmed to run on 98 Ron fuel or lower (the timing adjusts as required). If you fill up with fuel of a higher octane rating the ECU will only adjust the timing to its factory set max (which is 98 Ron). The result is you will not notice any power increases over and above the 98 Ron (although people swear they do, this is just wishful thinking).

Example;- If i fill my 996 TT with Sunoco GT Plus which is 109 Ron Fuel and run the car/ECU in std mode i dont notice any power increase over the std 98 Ron. However once i set the ECU to run the 109 Ron the timing advances and i have more power. The only difference you will notice is cost. 109 Ron £ 3.00 ltr, 98 Ron £0.98 ltr.

Just the oposite buddy.

Running on cruise drinks more fuel if the car is travelling on say hilly areas as you can make your throttle adjustments smoother with your own foot. The cruise also wants to keep you at the set speed so any incline will result in more throttle being applied where in reality when driving manually you may let the car slow slightly, Clarkson proved this on an A8 deisel when he drove to outer mongoliar and back on one tank of fuel.

I'll concede on hilly ground

I am expecting high 20's on the motorway as you are getting.

Helping my dad to run his new avant in, several times have got 30/32mpg on a 40mile run, that is taking it steady though!

Starmist that is very good mileage, light foot is the secret, but give it some now and then or it ain't going to bed in well.

I managed 25mpg from my first tank which was a healthy mixture of motorway, town driving and some "exploring" of the car's abilities. This was on half BP ultimate and half a tank of whatever the dealer had put in. I only usually use V-power but couldn't find a shell station, so I'm sure it will improve from now on.

Alex, I am going to be satisfied with that (25MPG) on cruises, I am not to hard on my cars, this one will be treated with care, so I am so excited can't wait til wednesday when I pick her up.

If he does this ... his car will develop less power ... have a search for other posts on running in

Andy I'm going to "vary" the revs a lot, for the first 1000 miles.
