Patent ID: 7985592

Claim:
A high throughput method for screening lubricating oil composition samples for compatibility with elastomers, 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 the 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 at least one base oil of lubricating viscosity and (ii) a minor amount of at least one lubricating oil additive in varying percentages in a plurality of test receptacles; (c) providing at least one elastomer; (d) measuring the elastomer compatibility of each sample to provide elastomer compatibility data results for each sample; and, (e) outputting the results of step (d).
