IF the quality of dery had risen with I the improvements in oil engines and their requirements in the way of fuel, there might be no need for the use of additives. Unfortunately, however, this is not always the case and the sulphur content has tended to increase as world supplies have come to depend to a greater extent on wells in the Middle East.
Sulphur maynot only form corrosive products during combustion but can result in exhaust, fumes which may be objectionable, if not dangerous.
Dieslip, manufactured by Slip Products and Engineering Co., Ltd., 95 Victoria Street, St. Albans, Herts, of whom Baron Beck is chairman, is intended to combat such effects and to keep oil engines, including their injectors and valves, more free from the formation of carbon, as well as to lubricate the injector pump. It is a composition of barium, cal cium, organic phosphates, lanolin anc manganese. The barium and calciurr promote detergency and help toward! engine cleanliness; corrosion is inhibitec by the phosphates, and the lanolin acb as a combustion catalyst.
This additive is not a new product, a! it was first introduced here in 1940. Fo! a time, British operators remainec sceptical, although sales grew rapidb in the Commonwealth and in Europe and it is now exported to 52 countries
In India, last year, 5m. gallons o dery were treated with it and in Kenya alone over lm., whilst throughou Europe it was added to over 90m gallons. Even M.A.N., of Germany during 1952-53, after conducting labor atory and practical tests, said that th, products gave good results and the; recommended it to users of thei engines.
