HC Deb 29 July 1965 vol 717 c168W
66. Mr. Buxton

asked the Minister of Power whether, in view of the increasing number of misleading trade names under which petrol is being sold, he will seek to make it obligatory for all retail pumps to display a sign giving the guaranteed octane rating.

Mr. John Morris

The British Standards Institution is examining the possibility of drawing up standard specification, associated with an agreed nomenclature, for different grades of petrol. I think this may be the best way of making progress towards the objective the hon. Member has in mind.
