Your petrol of choice ??

[MartinH]

Branded fuels is a clever marketing construct. With the exception of Fawley in Hampshire all UK refining is owned by specialist refining companies, not the big oil companies. There is no such thing as Shell or BP petrol. Fuel is picked up by tankers from the refinery "rack" based on price and logistics. Esso petrol in Inverness will most likely come from Inneos in Grange mouth, not ExxonMobil in Fawley. What is true is that the "brands" will supplement the "rack" fuel with additives. So, ironically the petrol companies do exactly what we all do; they buy on price and location and then choose, or not, to add their own snake oil additives.
