Let's have a look at some facts rather than unproven claims.
Good Idea
Fact 1 - Supermarkets now sell just under 50% of all fuel in the UK.
45.2% to be exact
Fact 2 - there are seven refineries in the UK. They are:
- Essar Stanlow
- Ineos Grangemouth
- Phillips 66 Humberside
- Total Humberside
- Murco Milford Haven
- Valero Pembroke.
- Exxon Mobil - Fawley
There are 9 refieries in the UK, You missed Lindsey and Teeside
Interesting that Shell do not own a refinery.
Fact 3 - all fuel in the UK comes from these refineries.
No it doesn't Shell V Power is Imported from Qatar from the Pearl Refinery a joint venture between Shell and Qatar Petroleum V Power is a GTL fuel of which there are very few refineries worldwide
Fact 4 - Fuel is distributed around the UK from various fuel distribution terminals. The refineries are connected to some of these terminals via pipelines. Here is a schematic showing these pipeline connections.

True for UK refined fuels
Fact 5 - all fuel produced from these refineries is produced according to a set standards - BS EN228 whatever.
I love facts
Advanced GTL fuels burn cleaner leave less deposits, the additives packages are better than supermarket fuels and when you have seen as many engines as I have stripped that have been run on supermarket fuels and failed then use Supermarket fuels at your peril but I'd add Millers additive. V Power, Momentum, or BP Ultimate only for me
