If this is also true in the EU, which I expect it is, does that mean there's absolutely no difference between supermarket diesel at £1.60/l and BP diesel at £1.80/l apart from a little bit of stuff, extra detergent or whatever, that BP squirt into it as it's pumped? I wonder if there's some kind of submarine marketing company that spends loads of time on car enthusiasts forums trying to plant the idea that there is a difference.
