Abstract
Methods and systems are provided for modeling an oil dilution qualitative indicator based on an integrated difference between a commanded air-to-fuel ratio and an engine air-to-fuel ratio as determined via an oxygen sensor, cumulative cold engine temperature operating duration, and fuel injection characteristics (timing, duration, number of injections) allowing fuel injection timing modifications that minimize oil dilution when the oil dilution qualitative indicator is greater than a threshold level.
