I'm fairly sure Esso is exactly the same stuff as supermarket fuel. BP probably the same. Shell is at least different.
I was on the isle of Wight a couple of years ago and pulled-up at a BP garage only to find that they were out of 98 octane BP Ultimate. I made inquiries at the kiosk asking about when the next delivery of BP Ultimate was expected. I was told (and I paraphrase)...
"Not until Thursday. We're expecting a tanker with high octane fuel over from the mainland on Thursday".I drove on for a couple of miles and found a Shell garage. As I pulled up to the Shell V-Power pump there was a sign which said "sold out". I made inquiries at the kiosk asking about when the next delivery of Shell V-Power was expected. I was told (and I paraphrase)...
"Not until Thursday. We're expecting a tanker with high octane fuel over from the mainland on Thursday".So, is Shell and BP fuel the same, or isn't it? I suspect that on the Isle of Wight it might be.
My understanding is that all the fuel companies, supermarkets included, have fuel swap agreements. I was led to believe that Shell V-Power was the only one that didn't. But, on the isle of Wight maybe Shell V-Power is what is sold as BP Ultimate. Shell V-Power is 99 octane whereas BP Ultimate is 98 octane. So it would probably be acceptable for BP to sell a fuel that was 1 octane higher than advertised, whereas not acceptable for Shell to sell 98 octane instead of the advertised 99 octane. So BP might be selling Shell V-Power?
Of course another explanation is that in fact two tankers, one from BP and the other from Shell, sailed from the mainland on that Thursday. Who knows, it's a mystery?
