Which petrol in your M

[The Livster]

As a long term diesel driver, soon to be M5 owner I was wondering which petrol you guys put in your M cars ?

With my diesels I added Millers to every other tank ,this seemed the accepted way by those ITK

With the M I will be using V Power, just wondered what other's used ,will have to dig out my shell loyalty card( not used since my 370z days)

Thats my understanding, its mainly for its cleaning properties. Does anyone feel they get better performance too ?

Thanks for the input guys , I know this subject crops up all the time and I have read loads of articles and reports. I am just asking what you M drivers use . People often feel their car runs better / smoother etc on a certain fuel . I will be using V as there is a shell station a couple of miles away on the route to my daughters, as pointed out , the cost is negligable .
