2-1/16 Gauge Oil Press. 0-120psi

The 2-1/16 Gauge Oil Pressure Gauge from AUTOMETER is an essential diagnostic tool for any serious automotive mechanic or performance enthusiast. Oil pressure is one of the most critical engine parameters to monitor—low pressure indicates bearing wear, gasket failure, or pump degradation, while consistent readings confirm healthy lubrication throughout the engine. This mechanical gauge provides real-time feedback on your engine's oil pressure performance, making it indispensable for troubleshooting, tuning, and preventive maintenance on street cars, track vehicles, and rebuilt engines.

Built with AUTOMETER's trusted mechanical movement, this 2-1/16-inch analog gauge reads from 0 to 120 psi—a range that covers most gasoline engine applications from stock daily drivers to naturally aspirated performance builds. The compact 5.2 x 4.65 x 5.5-inch form factor and lightweight 0.74 lbs construction allow flexible dashboard or A-pillar mounting in tight engine bays without adding significant weight. Mechanical gauges eliminate the need for electrical sender calibration and offer superior reliability compared to electronic alternatives, responding instantly to pressure changes so you catch problems before catastrophic engine damage occurs.

Whether you're diagnosing a suspect oil pump on a high-mileage engine, validating a freshly rebuilt bottom end, or monitoring an aggressive turbo build, this gauge pairs seamlessly with standard oil pressure sender ports found on most engines. Hobbyist mechanics and professional shops alike rely on AUTOMETER gauges for repeatability and accuracy during engine diagnostics. Installation requires only a basic mechanical sender and appropriate plumbing lines, making it the go-to choice for custom engine bays where electronic instrumentation may be unreliable or where traditional analog feedback is preferred.
