| 2. Messrs. Rolls-Royce Ltd., DERBY. 11th August, 1936. We have further authority from Mr. Harold Moore, the well known Petroleum Technologist, who supports our contention that Research Method is the only fair one, and on this we get a rating of 87½. In passing, it is also worth while noting that about 80% of competitors in the Ulster T.T. Race, where only standard fuels are used, have nominated Cleveland Discol. Finally, whilst we would naturally refer to your own ideas on this subject, we would say that it would not be necessary to make any jet adjustments for a Bentley car. We have had to aim at making a blend which is suitable for any car in its standard state, and we do not think that the Bentley is different to the majority. My own personal knowledge extends to the following Bentley owners who use Cleveland Discol with the utmost satisfaction, and in fact have been good enough to give us their own views. These are - Mr. C. R.{Sir Henry Royce} Fairey, Flight Lieutenant Staniland, Mr. A.{Mr Adams} C. Bertelli etc. Yours faithfully, CLEVELAND PETROLEUM PRODUCTS COMPANY.
