HC Deb 12 November 1987 vol 122 c197W
Mr. Allan Roberts

To ask the Secretary of State for the Environment what is the difference between lead-free and unleaded petrol; and when he expects each to be widely available in the United Kingdom.

Mr. Moynihan

Unleaded petrol is the technically correct way of referring to petrol to which no lead has been added. There is a British Standard Specification to which all unleaded petrol in the United Kingdom conforms. Lead-Free is simply a popular term for the fuel. As to availability, I refer the hon. Member to the reply I gave to the hon. Member for Glasgow, Central (Mr. McTaggart) on Wednesday 4 November.
