March. 1926. EAE/EC. Messrs. Rolls-Royce, Ltd., Derby. Dear Sirs, For the attention of Mr. E.W. Hives. We thank you for the opportunity which you gave to the writer and his colleague Mr. Limb on Thursday last to discuss with you the report upon Motorine C and Castrol X L. We were very much impressed by the trouble to which Mr. Adams had gone to obtain results which would enable him to formulate his opinion upon the oils in question. The only comment we desire to make is that the conclusion drawn by him upon the amount of asphaltic matter produced by blowing the oil at an elevated temperature is not one which we should have made. You will remember that in the report it was stated that Motorine C contained approximately 10% of fatty oil, and Castrol XL approximately 5%, and that after blowing Motorine C produced 0.18% of sludge, and Castrol XL 1.36%. Also that in view of the relatively large amount of sludge produced by the latter oil as compared with the former Prices' oil was in his opinion the better. Such an opinion might pass unchallenged were it not for the fact that the fatty oil contents were not the same in each oil, and this fact appears to have been overlooked when the final conclusions were formulated. | ||
