Patent ID: 7648837

Claim:
A high throughput method for screening lubricating oil compositions, under program control, comprising: 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 the at least one lubricating oil additive for combination to formulate a leading candidate lubricating oil composition for testing; (b) containing a plurality of the leading candidate lubricating oil compositions comprising a major amount of at least one leading base oil of lubricating viscosity candidate and a minor amount of at least one leading lubricating oil additive candidate in varying percentages in a plurality of test reservoirs, wherein the major amount of the at least one leading base oil of lubricating viscosity candidate is greater than about 50 wt. %, based on the total weight of the lubricating oil composition; (c) automatically measuring the oxidation stability of each leading candidate lubricating oil composition to provide oxidation stability data results for each leading candidate lubricating oil composition; and, (d) automatically outputting the results of step (c).
