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

The 2-1/16 Oil Pressure Gauge 0-100 PSI from AutoMeter is a precision analog instrument designed for serious automotive enthusiasts and mechanics who demand accurate real-time oil pressure monitoring in street cars, performance builds, and vintage restorations. This electric air-core gauge eliminates guesswork about engine health by providing direct feedback on lubrication system performance—critical data for tuning carburetor jetting, diagnosing bearing wear, and verifying oil pump function under varying load conditions. Whether you're running a modified small-block, naturally aspirated, or turbocharged engine, oil pressure trending reveals potential problems before catastrophic failure occurs.

Built with AutoMeter's proven air-core movement design, this gauge delivers fast needle response and smooth, stable readings without electromagnetic lag or oscillation that plague cheaper magnetic instruments. The short-sweep mechanism allows the needle to travel across the full 0–100 PSI range in one sweep, enabling rapid pressure checks at idle and under boost. The white face with black numerals and contrast markings ensures visibility in bright sunlight or dark engine bays, while the 2-1/16-inch diameter fits standard gauge clusters, custom panels, and overhead pods with minimal adapter requirements. Electric operation (not mechanical line-pressure driven) eliminates oil line plumbing complexity and provides safer sensor isolation from high-temperature engine bay environments.

This gauge suits street machines, drag cars, marine engines, and heavy-duty applications where oil pressure verification is non-negotiable. Installation requires a compatible 0–100 PSI sender unit threaded into the engine block or filter adapter—no special tuning knowledge needed, though experienced technicians will appreciate the repeatable accuracy for baseline diagnostics. The compact 4.7 x 4.4 x 4.8-inch profile and lightweight 0.46-pound construction make it ideal for weight-conscious builds or retrofit into tight underdash spaces. AutoMeter's track record for durability under extreme vibration and temperature swings makes this gauge a trusted choice in both amateur and professional shop environments.
