| BP. from Hs.{Lord Ernest Hives - Chair} X1588 Hsl/LG20.6.22. MIRACLE OIL. X1588 Referring to the attached. We recommend that you reply to this letter as follows:- "We have had no expérience with Miracle Oil. We have had numerous pamphlets and offers of free samples to test, but we have not considered it worth our while making any tests. We do not see any reason why you should obtain any better results with your Rolls-Royce car if you use Miracle Oil. If your car is not behaving satisfactorily on the oils we recommend, we shall be very pleased to help you in every way". Hs.{Lord Ernest Hives - Chair} | ||
