2-1/16 A/B Oil Pressure Gauge 0-100 PSI

The AutoMeter 2-1/16" A/B Oil Pressure Gauge (0-100 PSI) is a mechanical analog pressure gauge designed for real-time engine oil pressure monitoring in automotive and light industrial applications. This full-sweep gauge delivers accurate readings across its 100 PSI range, making it essential for drivers who need to catch pressure fluctuations before they become costly engine damage.

The 2-1/16 inch diameter face fits standard aftermarket gauge pods and dashboard openings, while the antique beige finish and beige face deliver a classic aesthetic compatible with custom gauge clusters and vintage restoration work. As a mechanical gauge, it requires no electrical power—pressure is measured directly via a mechanical sender line, eliminating electronic failure points and providing reliable operation in harsh underhood environments where electrical noise or EMI might compromise digital alternatives. The full-sweep movement provides smooth, continuous readings rather than stepped increments, allowing drivers to detect subtle pressure trends during idle, acceleration, and sustained highway operation.

This gauge is ideal for classic car restoration, hot rod builds, track-focused vehicles, and any application where direct pressure feedback enhances engine diagnostics and protection. Engine builders and enthusiasts rely on mechanical oil pressure gauges to verify proper oiling under load and confirm that new or modified engine internals are receiving adequate lubrication before extended driving. The 0-100 PSI range covers typical street and performance engine requirements, from idle pressures near 20 PSI to sustained operating pressures of 40–70 PSI depending on engine speed and oil viscosity.

AutoMeter's established reputation in aftermarket gauges ensures accurate calibration and robust mechanical construction. Mechanical gauges have been the standard in performance and diagnostic applications for decades—they require only a sender line from the engine block and deliver immediate, visible feedback that no dashboard light can match.
