§ Sir Dudley Smith
To ask the Secretary of State for the Environment what official efforts are being made to educate drivers about the various grades of unleaded petrol and their application to different types of car engines.
§ Mr. Portillo
From 1 October, all new cars will be required to be able to use 95 octane unleaded petrol. The vast majority can already do so. The Government have issued a free booklet "Adjust to Unleaded" which gives guidance on the use of this fuel in existing cars. The booklet also deals in general terms with the higher octane grades which will enable certain additional existing models to run on unleaded petrol. It would, however, be excessively complicated to include detailed information on individual models, and motorists who are in doubt should consult their vehicle manual or seek advice from a qualified source.
