Micro-conspiracy

To overthrow your ideals is their sole object. Insinuating themselves into the most vital places, they seek only to destroy. Abrasive particles of microscopic dimensions, they penetrate freely through all but the most efficient filters, and wear away all the vital bearing surfaces. The Purolator 'Micron ic' filter, however, arrests them; its plastic-impregnated paper (of specially controlled texture pioneered by Purolator) has the requisite fineness, yet with such a generous area as to pass the oil freely. Be sure, therefore, to change the element when you change the oil, and safeguard the durability of your engine.
