Well I know a guy who's delivered fuel for over 15 years, and he doesn't add anything, no 'additives.' It comes out of the suppliers terminals and gets delivered to garages as it is. It is a bonded item and once in the tanker, it is illegal for anyone to access the fuel. Also illegal at a petrol station to access the fuel tanks for whatever reason, except to take a manual 'dip' reading if the gauges are suspect.
