An engine oil gauge, 0-80 PSI, chrome is a mechanical gauge that measures the pressure of the engine oil circulating through the engine. It is typically mounted on the dashboard of the vehicle and has a dial with a needle that indicates the oil pressure. The gauge has a range of 0-80 PSI, which is the normal operating range for most engines.
The gauge works by using a spring-loaded diaphragm to measure the pressure of the oil. The diaphragm is connected to a needle on the gauge dial. As the oil pressure increases, the diaphragm expands and pushes the needle up the dial. The needle indicates the oil pressure in PSI.
Chrome engine oil gauges are popular because they add a touch of style to the dashboard. They are also often more durable than gauges made from other materials.
If the oil pressure drops too low, the engine can overheat and seize up.
