An engine lubricant was developed for diesel and gasoline engines covering all service and climatic conditions in Central Europe.The performance spectrum and reasons for formulating a SAE 20W-40 multigrade with a viscosity of 4800 cP at 0°F are explained.A review of the development and test work conducted includes studies indicating the lubricants behaviour in gear boxes, hydraulic systems and other off -highway arid construction equipment.Typical examples of European mixed fleet together with service results obtained from the field are demonstrated.Data compiled show stay-in-grade characteristics, excellent wear protection and engine cleanliness.In comparison with SAE 20W-20 and SAE 30 monogrades oil consumption is reduced.
