At what stage do they carry this out?That’s true but different brands add different additives to make it their own. Talking to a guy who works for Esso he said that’s the difference between supermarket fuel and theirs, the additives.
He only uses super diesel as it keeps the engine cleaner as well as petrol.
I have also been told this.
But I have also been told by a friend who was a fuel delivery driver for Shell......and he says it's not the case.
