(copy attached for Hs{Lord Ernest Hives - Chair}). as a matter of fact we recommend 8,000 to 10,000 miles as about the average mileage for decarbonising. The probability is that the other car referred to by the customer is a lower compression engine. We are sending a copy of your memo. to Hs.{Lord Ernest Hives - Chair} as he may have some comments to add with regard to the question of oil and air filters and the advantages or otherwise of these.
