0-100 Oil Pressure Gauge

The AUTOMETER 2522 0-100 Oil Pressure Gauge is an essential engine monitoring instrument for any serious vehicle builder or performance enthusiast. Whether you're tuning a street engine, diagnosing bearing wear, or verifying oil system integrity after a rebuild, this mechanical gauge provides real-time feedback on one of the most critical engine parameters.

Oil pressure directly correlates to bearing life, cam lobe protection, and overall engine longevity—making this gauge invaluable for anyone who wants confidence in their powertrain's health during break-in periods, sustained high-RPM operation, or troubleshooting hydraulic failures. AUTOMETER's proven mechanical design eliminates electrical dependencies and sensor drift, delivering accurate pressure readings across the full 0–100 PSI range. The gauge employs a Bourdon tube movement with direct capillary line connection to your engine's oil gallery, ensuring instantaneous response without electronic lag or calibration drift over time.

This direct-sensing architecture makes it ideal for engine testing environments, track sessions, and street applications where reliability and repeatability matter more than digital precision. The compact 4.7-inch diameter face mounts easily into existing dash openings, gauge pods, or custom panel installations, while the robust construction withstands vibration, temperature cycling, and the thermal stress of high-output engines. This gauge suits vintage and modern engine builds alike, providing essential information for maintaining optimal performance.
