A system for tracking oil health of an engine includes an electronic fuel injection system which includes an electronic governor control unit. The electronic governor control unit is programmed to track engine parameters, calculate oil health based on the tracked engine parameters and on engine type, and display an indication of oil health.

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 system and method for monitoring a service life of lubricant that is applied to vehicle components is disclosed. The method includes receiving at least one input parameter. The input parameter relates to the vehicle's operation. The method also includes determining a remaining service life of a lubricant. The lubricant is applied to a driveline component of the vehicle. The determination of the remaining service life of the lubricant is based on the receiving of at least one input parameter.

Disclosed herein are systems and methods for estimating remaining useful life of vehicle engine oil. Such methods may comprise operating at least one processor to: receive telematics data originating from a plurality of vehicles, the telematics data comprising odometer data and engine oil quality data associated with each of the plurality of vehicles; determine, for one or more of the plurality of vehicles, a start point of a current oil cycle based on when an oil cycle event previously occurred by identifying within the engine oil quality data: a first series of engine oil quality datapoints, and a second series of engine oil quality datapoints immediately following the first series, a difference between a final datapoint of the first series and an initial datapoint of the second series being greater than a predetermined threshold; synchronize the odometer data and the engine oil quality data by associating odometer datapoints and engine oil quality datapoints reported within a same time period; determine a remaining useful vehicle engine oil distance by applying to synchronized odometer and engine oil quality data reported during the current oil cycle a regression model; and determine a remaining useful vehicle engine oil time by converting the remaining useful vehicle engine oil distance thereto based on an average difference in odometer datapoints reported during a selected time period, whereby the remaining useful life of vehicle engine oil is estimated based on vehicle operational factors associated with the current oil cycle, and independently from those of a previous oil cycle.

A method for determining engine oil system health includes determining an oil level in an engine oil sump of an engine, determining an oil consumption rate of the engine based on a current oil volume and a time at which the oil was last replenished, determining a remaining useful oil volume based on the oil consumption rate and duty cycle data of the engine, and generating an alert in response to the oil consumption rate being greater than a predetermined threshold, the alert comprising a command to a controller associated with the engine to cause the engine to perform an action.
