There is provided a work machine. A reserving chamber reserves lubricating oil to be supplied to an engine. A channel forming member forms a channel of the lubricating oil from the reserving chamber to the engine A press-feed unit press-feeds the lubricating oil reserved in the reserving chamber to the engine via the channel forming member. A float floats on an oil surface of the lubricating oil reserved in the reserving chamber A detection unit provided in the reserving chamber and detects the float A determination unit determines a tilt state of the reserving chamber based on a detection result of the detection unit A control unit controls the press-feed unit based on a determination result of the determination unit.

Systems and methods for capturing fluid change history in a vehicle are provided. A method includes: detecting, by a computer device, a fill cap is removed from an inlet port of a fluid reservoir or a drain plug is removed from an outlet port of the fluid reservoir; activating, by the computer device and based on the detecting, one of a fill sensor and a drain sensor; obtaining, by the computer device, fluid characteristics data from one of the fill sensor and the drain sensor; determining, by the computer device, at least one fluid parameter based on the fluid characteristics data; and transmitting, by the computer device, the determined at least one fluid parameter to a remote system via a communication network that is external to the vehicle.

A controller includes: a control unit configured to detect, based on information from a sensor mounted on a vehicle, a first event indicating that engine oil is discharged from an engine of the vehicle, or a second event indicating that the engine is replenished with engine oil; and a storage unit configured to store the result of detection by the control unit as a history of oil change.

An engine oil dipstick for monitoring an internal combustion engine comprises a processor and a sensor module. The sensor module is configured to sense a characteristic of the internal combustion engine and to output data representative of the sensed characteristic to the processor. The engine oil dipstick is configured to provide a housing for the processor. The processor is configured to determine a value representative of the firing frequency of the internal combustion engine based on the output data.

The present invention comprises an apparatus and method for replacing an original equipment manufacturer air-oil separator apparatus having an integral pressure control valve (“OEM-AOS” system) in a vehicle. The OEM-AOS system is disconnected from the engine air intake. The integral pressure control valve is disabled. An accumulator for collecting oil from by-pass combustion gas is connected to the OEM-AOS system. A discrete pressure control valve (“discrete-PCV”) is connected to the accumulator and to the engine air intake. The discrete-PCV is located within the vehicle at an easily accessible location so that it can be quickly accessed and replaced when necessary. The accumulator includes a sensor that is operable to send a warning signal to a vehicle operator when the vehicle needs to be serviced to remove condensed oil from the accumulator.
