A device used to measure the operational force exerted by lubricant within an internal combustion system, indicating the efficacy of the oil pump and the condition of the engine’s internal components. As an example, observing a lower-than-specified reading during engine operation suggests potential issues like a worn oil pump, internal leaks, or blocked oil passages.
Accurate monitoring of lubricant force is critical for maintaining engine health and preventing catastrophic failures. Regular assessment using this type of instrument allows for early detection of developing problems, facilitating timely repairs and avoiding costly engine overhauls. Historically, basic gauges provided rudimentary indication; modern units offer digital displays and data logging capabilities for detailed analysis.
