2-1/16in Ultra-Lite Oil Tank Temp. Gauge

The AutoMeter 2-1/16in Ultra-Lite Oil Tank Temperature Gauge (model 4346) is a precision mechanical instrument designed for accurate engine oil temperature monitoring in high-performance and marine applications. This full-sweep analog gauge reads continuously from 140 to 340 degrees Fahrenheit, providing the real-time thermal data essential for preventing engine damage and optimizing performance during sustained operation.

The 2-1/16 inch diameter face with silver background fits standard gauge clusters and custom installations with minimal dashboard footprint. The mechanical design eliminates dependency on electronic sensors, offering reliability in extreme environments where electrical connections may fail or corrode. A full-sweep needle provides intuitive, at-a-glance temperature status—critical when monitoring coolant or oil thermal limits during high-load conditions. At 0.81 lbs, the ultra-lite construction keeps overall vehicle weight minimal without sacrificing durability or readability.

This gauge serves operators of high-performance vehicles, marine engines, heavy equipment, and vintage restoration projects where precise temperature monitoring prevents catastrophic failure. Users requiring redundant or secondary temperature indication—especially in offshore, desert, or off-road environments where engine stress peaks—benefit from the mechanical reliability of this instrument. The 140–340°F range covers both gasoline and diesel engine oil operating windows, making it versatile across platform types.

AutoMeter's mechanical gauges are industry standard in competitive motorsports and professional marine operations due to consistent accuracy and zero-maintenance operation. This model's compact size and straightforward installation make it an ideal upgrade or backup instrument for any operator who demands real-time engine thermal data without electronic complexity.
