To ask the Secretary of State for the Environment what steps he is undertaking to establish the incidence of motor vehicles being converted back to be able to run on leaded petrol; and if he will make a statement.

Discussions with motoring organisations following a recent press story produced no evidence to suggest that readjustment to leaded tune is widespread. A minority of cars—their number diminishing all the time—cannot be adjusted to run on unleaded petrol. This is made clear in the Department's booklet "Adjust to Unleaded", and in information diseminated by the vehicle and petrol trades. In all other cases, however, provided that the manufacturer's guidance is followed by competent mechanics, I am confident that motorists will encounter no problems in using unleaded petrol. They will, of course, both contribute to an important environmental improvement and save money by doing so.
