Abstract:
1. A high throughput method for screening lubricating oil composition samples, under program control, comprising the steps of: (a) conducting molecular modeling of at least one base oil of lubricating viscosity and at least one lubricating oil additive to provide leading candidates of the at least one base oil of lubricating viscosity and at least one lubricating oil additive for combination to formulate a leading candidate lubricating oil composition sample for testing; (b) containing a plurality of the leading candidate lubricating oil composition samples comprising (i) a major amount of the at least one leading base oil of lubricating viscosity candidate, and (ii) a minor amount of the at least one leading lubricating oil additive candidate in varying percentages in a plurality of test reservoirs; (c) measuring deposit formation of each sample comprising heating the sample to a predetermined temperature in the presence of a substrate and determining the amount of deposits formed on the substrate after a predetermined period of time by determining the weight of the substrate containing deposits and comparing the determined weight with the weight of the substrate to provide deposit formation data for each sample; and, (d) outputting the results of step (c).
