1. A system, configured to monitor vehicle engine oil contaminants using output of a vehicle sensor, comprising:

  • a hardware-based processing device configured to perform operations comprising;

    determining a time cycle indicative of a duration during which the vehicle has been in operation;

    receiving output from the vehicle sensor indicative of a temperature of the engine oil;

    determining, based the output of the vehicle sensor, a temperature of the engine oil;

    determining 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.
