Systems and methods for accurately compensating for a change in amount of unwanted fluid diluted in engine oil resulting from a recent long trip

A method, for implementation by a system comprising a vehicle sensor and a hardware-based processing device configured to monitor vehicle engine oil contaminants using output of the vehicle sensor, the method comprising:

• determining, by the system, a time cycle indicative of a duration during which the vehicle has been in operation;
• receiving, from the vehicle sensor, output indicative of a temperature of the engine oil;
• determining, by the system, based the output of the vehicle sensor, a temperature of the engine oil;
• determining, by the system, whether the temperature of the engine oil is greater than a threshold;
• and
• generating, by the system, in response to determining that the temperature of the engine oil is greater than the threshold temperature, a correction factor indicative of an amount of contaminant removed from the engine oil during the time cycle.

A non-transitory storage device configured for use with a system for monitoring contaminants of vehicle engine oil using output of a vehicle sensor, the non-transitory storage device comprising instructions that, when executed by a processor of the system, cause the processor to perform operations comprising:

• determining a time cycle indicative of a duration during which the vehicle has been in operation;
• receiving, from the vehicle sensor, output indicative of a temperature of the engine oil;
• determining, based on the output of the vehicle sensor, whether the temperature of the engine oil is greater than a threshold;
• and
• generating, in response to determining that the temperature of the engine oil is greater than the threshold temperature, a correction factor indicative of an amount of contaminant removed from the engine oil during the time cycle.
