HIGH THROUGHPUT SCREENING METHODS FOR LUBRICATING OIL COMPOSITIONS

摘要

Method for determining dispersancy performance for a plurality of fluid samples of different compositions is provided. Each sample includes one or more base oils of lubricating viscosity (110) and one or more lubricating oi l additives (120) and a predetermined amount of an oil-insoluble material. The methods can advantageously be optimized using combinatorial chemistry, in which a database of combinations of lubricating oil compositions are generated. As market conditions vary and/or product requirements or customer specifications change, conditions suitable for forming desired products can be identified with little or no downtime.
