Discussion
I've heard it said that a V12 user should only ever compute the fuel economy once - but perhaps discussing range is a bit less traumatic?
Just put 86L in with 400kms/250 miles on the trip counter with some city driving (e.g. 13mpg). The petrol pump icon had just appeared on rev counter panel.
Given the tank capacity (I believe 105L/23 gallons) I guess that I would have had a reserve of 19L so perhaps another 100kms/60miles in her, if cruising?
What sort of range can you expect to achieve on longer journeys?

Just had a quick flick back to the old EVO long term 550 test... and 16-18mpg / 320 mile tanks were 'the norm' with 360 miles seen.

Would have thought that the 575M which is 6% lower on CO2 on paper would show a comparable improvement but we'll see how it goes in practice.
One might have thought that the lower idle speed afforded by the COP ignition would have contributed to a reasonable improvement in the urban mpg but it turns out that the old mill is quite efficient (or should I say inefficient) at turning fuel into heat at 0 mph!

Any benefits to report running 98 over 95RON?
Just read the manual that states that that the Fuel Reserve ideogram/icon should appears when there's approx. 18-20L left and then last bar on the fuel gauge (which I believe will have started flashing by this time) would be expected to go out when down to the last 12L...

I usually put Shell VPower/VMax in as was told to do so when I asked similar question when I bought the car. But when I put Normal in I cannot tell the difference performance wise.
I would never fill-up at a supermarket. Just too many stories about low grade fuel at these places - probably put about by Shell/Esso/BP PR machine!

I've been using 98 so far as that's what I've been putting in my other car for years but now that I read that 95 is approved/acceptable in the F, I will give that a go.
My local Shell forecourt only offers 95 and V-Power 100 but the price delta is significant and as it's not clear that this generation of F can make use of the higher RON although I suppose that it might still be worth it from time to time / on track etc. and there could be something in the low friction claims/guff.... However, adding a couple of drops of snake oil into each tankfull might also have the same effect

I was able to spot the difference quite quickly, with a notable difference in performance especially around the mid range. As a result I have only run Shell's high octane stuff for many years now. I understand that it's the highest octane fuel on the market (99+?). BP's best stuff is only 97 from memory, but I'll be happy to be corrected.
Another upside is that when I used to run it on the normal stuff, after a few tanks I was noticing that warm starting was starting to become an issue. I don't have any problem at all with Shells finest.

we have averaged what looks like 19mpg over 1300 miles which I think is brilliant from a car that is only supposed to do 12.4 mpg combined
Ok that was for a 550 but that equates to 350-400 milesIn normal driving (which for me includes driving 15mins in/out of London at the beginning/end of each trip) we seem to average 15-16mpg
