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 method of diagnosing a lubrication system of an engine includes controlling an oil pump with a control signal. The control signal is a command having a value for a desired lubrication fluid pressure from the oil pump for a current operating state of the engine. A processing unit compares the value of the control signal for the current operating state of the engine to a threshold control value for the current operating state of the engine. When the processing unit determines that the value of the control signal for the current operating state of the engine deviates from the threshold control value for the current operating state of the engine, the processing unit analyzes the value of the control signal to identify a fault in the lubrication system.

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.

Systems and methods are described for predicting a remaining oil life in an engine of a vehicle. One or more parameters of the engine can be monitored over a period of time. A hot compartment temperature can be determined from the parameter. A condition of the oil can be determined based on the hot compartment temperature, and the condition of the oil can be displayed.
