The New Orobis Additive Plant

MORE HAS BEEN WRITTEN ON THE subject of lubricating oil additives in the past ten years than in the whole seventy to eighty years since petroleum oils were first used. As a result, the works engineer, the motorist or anyone who uses sufficient lubricating oil to take any interest in the subject of lubrication, frequently forms the idea that additives are something new. This is not so, since anything added to an oil to improve its properties is technically an additive. From early days such materials as sulphur, graphite, and similar substances have been incorporated by both oil manufacturers and oil users to help overcome lubrication problems. These products were early types of oil additives.
