AERO ENGINES USE FILTERED OIL WITH NO LOSS OF EFFICIENCY AND A GREAT SAVING IN COSTS Completely remove the impurities, collected during use, from old oil, and it is essentially the same as it was immediately after refining, independent and scientifically unquestionable . tests have proved that refined oil is at least equal in lubricating qualities to new, unused oil. Over 6,000 users of Stream-Line Filters appreciate these facts : the suitability of the filter for use in connection with aero-engine oil is established by experience with hundreds of aircraft. Every abrasive particle—even colloidal carbon—is removed when oil passes through a Stream-Line Filter. It emerges as clear and as suitable for lubrication purposes as new, unused oil. The economies which such a system make possible are enormous, while the added engine efficiency derived from more than usually frequent sump drainage is of equal value. These facts can be substantiated ! They are important facts. • ' Facts you should know all about.
