I'm currently giving V-power a go.
First four tanks in my new car (done just over 1,000 miles now) were normal Shell unleaded (have avoided supermarket fuel for a while now and feel that my cars have run better for it) and I got between 30 and 31 mpg average for the tank. Thought I'd give V-power a go for a few tanks to see if I get any difference ...and so that the little un can get the Ferraris!.
Filled up with 46 litres of V-power the other night and initial observations (after 90 miles) are that the car definitely seems smoother when cold, and possibly a bit keener when I put my foot down. Current average mpg is reading 32.9.
Will report back as time goes on.... need to bear in mind though that the engine will still be loosening up at this stage so not sure how much of any change in performance / efficiency will be related to this rather than fuel.
