Patent ID: 7917307

Claim:
An oil sample analysis calculator for analyzing results of oil samples from an engine, the oil sample analysis calculator comprising: an input module which receives an input data set, the input data set includes concentration levels of at least one of metallic and chemical contaminants in an oil sample; a processing module which receives the input data set from the input module and corrects the input data set based on at least one of an amount of oil added to the engine and an amount of oil removed from the engine; and an output module which receives the input data set corrected by the processing module and outputs an output data set, wherein the output data set comprises one of a trend warning and a rate of change warning based on a predetermined set point, wherein the input data set comprises: a first oil contaminant concentration corresponding to a first oil sample; a second oil contaminant concentration corresponding to a second oil sample taken after the first oil sample; and a third oil contaminant concentration corresponding to a third oil sample taken after the second oil sample, and wherein the processing module comprises an algorithm which compares the first oil contaminant concentration, the second oil contaminant concentration and the third oil contaminant concentration for generating the output data set.
