| MARMON AUTOMOBILE COMPANY OF NEW YORK, Inc. 1880 BROADWAY AT 62ND STREET TELEPHONE 5090 COLUMBUS NEW YORK IN REPLY REFER TO May 6, 1924 Mr. F.{Mr Friese} M.{Mr Moon / Mr Moore} Prindle, 267 Fifth Avenue, New York, N. Y. Dear Sir: We are naturally and genuinely interested in the performance of your car, and anything we can suggest to improve its performance and cut down cost of operation, is to our mutual interest. For the past six months we have been using in our demonstrating cars, Caspar Oil and we are so well satisfied with the results that we feel we owe it to our Owners to bring it to their attention. We find by its use that we secure more power, the engine runs smoother and quieter; gasoline mileage has been increased; less carbon is formed and this carbon is soft and does not carry fire causing pre-ignition. All Oil Concerns recommend draining the crankcase every 500 miles. We recommend draining Caspar Oil at 1500 miles. This oil is therefore less expensive in the long run. We offer you the following example: Oil @ 28¢ per Qt. - 1500 miles. Crankcase filled 3 times - 12 Qts. to filling 10.08 Caspar Oil @ 40¢ per Qt. - 1500 miles. Crankcase filled once - 12 Qts. to filling 4.80 Saving to you --- 5.28 We carry Caspar Oil in stock and will be glad to drain your crankcase and fill. Enclosed find booklet. Yours very truly, MARMON AUTOMOBILE COMPANY OF NEW YORK, Inc. 654 West 57th Street, City. [Signature: Stanley A.{Mr Adams} Zweibel] Service Manager. SAZ:HK{Col. T.
