Show Standard Oil To Market New Anti-Knock Gas Standard Oil' Company of Calif, today announced the West's first automotive gasoline made with an aviation anti-knock fuel formula. This aviation blend is available only in Standard's premium grade gasoline. Company engineers say the new gasoline is designed to meet the special performance . requirements of modern engines. These special needs are the result of increased compression ratios, radical cylinder cylin-der head designs, and critical valve operation. Extensive tests in Standard's laboratories and on the road indicate indi-cate the new gasoline lengthens valve life and reduces combustion chamber deposits, thus improving octane performance. A substantial reduction in wear rate of piston rings and cylinder walls also is reported in the .tests. ' Spokesmen for Standard Oil say the same benefits improve' performance per-formance of older cars as well. Primary purpose of the new blending, blend-ing, however, is to make possible all the' performance designed into modern high-compression engines. |
