THE RESEARCH EFFORT SURVEYED No. 3 LUBRIZOL INTERNATIONAL LABORATORIES

SO MUCH emphasis has been placed on additives since World War II that one might be excused for imagining that oil is little more than a carrier for such additives, This may, in part, be true, but the fact remains that no liquid has come along which can fulfil the functions of a petroleum oil. Synthetic lubricants, gas films and such lubricating resins as polytetrafluoroethylene have come into the picture for specialized applications, but the major responsibility for keeping civilization's wheels turning remains almost wholely with oil. The awareness of this as a state of affairs for many years to come sent the chemist and engineer in search of ways and means of re‐inforcing an oil where needed, and so there has grown up an important branch of lubrication technology, additives.
