Does supermarket fuel have 'lower capability' additives?
I have been advised that petrol additives are actually added during fuel station delivery. Non-branded stations, such as supermarkets, receive fewer or or lower capability additives which is partly why fuel from those sites is often cheaper. Is there any substance in that?

Brands such as BP and Shell do use extra additives for their premium fuels with various claimed benefits such as improved fuel economy. But ultimately all fuel - branded or non-branded - has to meet the same legal standards in the UK and supermarket fuel usually comes from the same refineries as premium brands.
