I have always wondered if supermarket petrol is inferior quality to the stuff you get at the likes of Shell or BP garages. Some people say it's identical, some people swear that it's different.
Anyway, a few nights ago I was listening to TalkSport on the radio and they were talking about the potential fuel protests. This petrol tanker driver called in, and among other things he said that the stuff from supermarkets is terrible low quality and "you might as well pour salt in your engine".
This got me thinking about this again. If supermarket petrol is lower quality and would damage your engine, why do car manufacturers not tell us to avoid it? Why don't Shell etc advertise that their petrol is superior to the competition? It doesn't really make sense to me. If supermarket petrol really is worse then surely they'd be telling us?
But that's two tanker drivers I've heard now say that there is a difference. Do you think their employers tell them to say that? Seems odd.
