' (Coniinutd on poga 164) SINCLAIR it' READER SERVICE SECTION fowt>g WAV 1953' to Prove A lot of people depend on Mr. W. T. Elliott. For it's his job as Power Plant Supt. to see that the City of Denton, Texas has unfailing light and power 24 hours a day. To help live up to that responsibility, Mr. Elliott pampers his hard working Nordberg Duafuel engines -- makes sure they're lubricated with (he finest oil available. He says, "We've been using Sinclair rubilene since 1948 with very satisfactory results. Cylinder liner wear is only '/$ of 0.001 inch per 1,000 hours running. Piston ring life is 16,000 hours of operation and we get 6,100 H.P. hours per gallon of oil... Facts like those have definitely sold me on RUBILBNB Why not let the facts prove to you, too, rubicenb is a superior lubricating oil. Phone your local Sinclair Representative or write to Sinclair Refining Company, 600 Fifth Avenue, New York 20, N. Y. DIESEL LUBRICANTS save wear and replacements 143
