I have always used the Shell V-Power as that is what was recommended to me when I bought my WRX STi Type UK and have used it ever since with the one exception in the west country - Dorset to be exact - and used 20quids worth of BP ultimate and it seemed fine but I am now back to the diet of Shell V-Power and is it worth buying shares in Shell as the cost of it is going through the roof at the mo.
But I did see a piece on this week's BBC F1 coverage when Alonso used both his regular fuel for his F1 car and then switched over the V-Power and he said it didn't make that much difference to him and with a bit of remapping work would be ok. Opinions?
