VITAMIN FOR BATTLE WAGONS! Nobody ever saw a vitamin as it exists in a natural food. But there is no question of its presence – or absence – when judged by the effect of the food on the human body. Years before Pearl Harbor, scientists at the “University of Petroleum,” Shell’s research laboratories, were taking molecules apart in an effort to discover the natural “vitamin” to prevent rust in the turbines that drive our ships and power our industry. They thought that RUST might be regarded as due to a “deficiency disease” – as beri-beri and pellagra ar deficiency diseases of people lacking the right vitamins. Question their theory if you will, THEIR RESEARCH SUCCEEDED. They found their “anti-rust vitamin” – in time to meet the greatest need in our Navy’s history. Like a natural food vitamin, it is invisible. They know it is present, or absent, by the result. When it is added to turbine oil, for example, a film forms over the metal which is impervious to moisture even under high bearing stress. The turbines in our Navy’s battlewagons have been stepped up in efficiency to the point where they consume less fuel than those of any other Navy – giving our ships greatly increased range. In global warfare you know what this means. Successful operatio of these improved turbines – their resistance to “Black Rust,” whose attack is deadliest when the pressure is greatest – is a tribute to Shell’s “anti-rust vitamin. ” . . . . . 1944 Shell Oil Company Ad, A5478.
