A method for determining a consumption amount of an engine oil of a vehicle includes starting, by a controller, an engine of the vehicle; and extracting and determining, by the controller, a consumption amount of the engine oil of the vehicle per unit time from a memory storing the consumption amount of the engine oil per unit time, in response to a speed of the started engine and an intake air pressure of the started engine.

A system includes an electronic fuel injection system of an engine, the electronic fuel injection system including an electronic governor control unit for controlling various functions of the engine.

Methods and systems are provided for diagnosis of oil dilution in an engine. In one example, a method may include sealing a crankcase and spinning an engine unfueled to heat and vaporize the oil in response to detection of rich engine operation. Pressure measurements at the sealed crankcase may be collected and compared to a baseline to diagnose a presence of fuel in the oil.

A system includes an electronic fuel injection system of an engine, the electronic fuel injection system including an electronic governor control unit for controlling various functions of the engine.

Provided is an engine oil deterioration diagnosis device (10) comprising annual traveling distance calculating part (16), a used hour calculating part (18), a severe condition determining part (20), an oil traveling distance calculating part (22), an oil traveling distance accumulating part (24), and an engine oil deterioration diagnosis part (26) for diagnosing that engine oil is in a state of deterioration when an oil traveling distance accumulated by the oil traveling distance accumulating part reached a predetermined value, wherein the oil traveling distance calculating part (22) comprises an oil traveling distance addition correcting part (32) for calculating the oil traveling distance by adding a predetermined value to the traveling distance when the severe condition determining part determines the state as the severe condition.

A system includes an electronic fuel injection system of an engine, the electronic fuel injection system including an electronic governor control unit for controlling various functions of the engine.

A computer implemented method system and apparatus for determining remaining life of engine oil in an engine includes generating reference engine profile data by determining reference engine parameters of a reference engine; determining reference engine oil lubrication data based on mechanical testing of an oil sample from the reference engine; generating a reference model by associating the reference engine profile data with the reference engine oil lubrication data; receiving the reference model at an engine apparatus; measuring engine parameters relating to operation conditions of an engine of the engine apparatus; and determining remaining life of engine oil in the engine of the engine apparatus using the reference model and the engine parameters.
