does anyone actually get better mpg with v-power?

95 gives me 330 miles to a tank, v-power (98) gives me 290-300 a tank, but the performance of shell over the others is much better, even the shell 95 i find better than Esso or BP 97 but i try not to do this too much, if i cant find a shell then i will only ever put the premium of any other station in. if im tight for cash (lets face it, everyone is now petrol is a million pounds a drop) i use shell 95. Tescos momentum seems ok, but i find it can be slowish to get going over shells v-power.

little update for you, my mpg seems to be getting better, might have been a coincidence but i took it for a proper blast down the er...autobahn? yeh the autobahn and mpg seems to have improved, but, since the weathers been a bit nicer the flappy paddles have been in action alot more. so yeh, mpg has since dropped through no fault of the engine of course
