Pick up my new M5 on Tuesday (v excited), do these cars prefer a certain flavour of fuel? There's a BP garage close to where I live and a Shell garage 15 mins away. I guess BP ultimate and shell vpower are similar but what about Tesco's super unleaded?
Anything else I should be aware of, or is it essentially a five series with a big engine?

There's a good explanation quoted here -

Your M5 will definitely run optimally on super, whether the difference is noticable to you or not! I would have thought that even without driving it hard it will overall "feel" better, smoother running and marginally improved consumption. Try running it to near empty and then filling with super - it might take a few miles for the ECU to "learn" that it has higher octane fuel and adapt ignition timings accordingly.

Would be interesting to see the difference of an M5 using regular and one using V Power (or similiar), I'm not sure there would be much between them?

Why would you think that?I know of people having engine failures from not using appropriate fuel in their 350zs surely the M5 is also recommended to be run on super to avoid these sort of issues? Or am I making stupid assumptions

It will make less power on 95 RON. I myself don't understand why someone who bought or leased a £70k car would look to save £3 per tank.
Use the best stuff you can.
Money isn't the issue or has ever crossed my mind, it's fast enough as it is and I'm simply interested in opinion.Use the best stuff you can.
I will almost certainly start to use high octane from now on

There is a noticeable difference in quality of fuel between brands, it's a question which comes round every few months.
Google it, 5th gear did a review using a 330bhp Impreza (I think) and the difference between supermarket fuel and Shell V-Power was 10-15hp.
I myself have noticed either smoother running and/or more fuel economy.
I only ever use Shell fuel for my daily, and V-Power for my M3 - your M5 is an £80k car, are you really quibbling over a few pence per litre?
