§ 74. Mr. E. L. Mallalieu
asked the Paymaster-General if he will take steps to arrange that on every pump from which petrol is sold is displayed the octane rating, so that a motorist will know what quality of petrol he is buying and can select the cheapest kind which will give the best result in his particular engine.
§ Sir I Horobin
This is a matter for the oil trade, but a difficulty about the hon. Member's suggestion is that quality and suitability often do not depend on octane number alone.
