The Oil Pressure Gauge keeps you informed on oil pressure so you can spot drops during startup, hard driving, or sustained load before they lead to engine damage. A military-grade pressure transducer provides highly accurate PSI data, giving you a clear view of lubrication system performance in real time. A precision stepper motor keeps the needle smooth and steady—no fluctuation, no guesswork. Built with a durable housing and solid aluminum bezel, it’s made for real driving conditions and long-term use. Made in the USA and backed for life.

Track-Tested. USA-Built. Backed for Life.

Built to last. Backed for life.
  • Lifetime warranty on internal circuit board electronics
  • 5-year coverage on sensors and wiring
  • Applies to gauges purchased since Jan. 1, 2006

Every Speedhut gauge includes a lifetime warranty* on the electronic circuit board inside the gauge case. It is the core of the gauge — the part responsible for the precision communication that delivers the accuracy and performance Speedhut is known for.

Sensors, wiring, and other external components are covered by an unlimited 5-year warranty.

This combined lifetime / 5-year warranty applies to the original purchaser.
*For your lifetime — as long as you own the gauge — we stand behind it.
Speedhut Inc warrants products to be free from defects in materials or workmanship. This warranty is limited to repair or replacement. Speedhut Inc is not responsible for incidental or consequential damages. Improper use, installation, or unauthorized modifications void this warranty.


Ensure you are using our sensor, most other sensors will not work with our gauges.


With the harness disconnected from the sensor and the gauge powered on, measure the voltage across the red and black wires in the harness at the sensor end. Here you should see 4.9-5 volts. 


Once you have confirmed the voltage, short the red wire to the white wire, this should make the gauge sweep full scale. 


With the harness still disconnected from the sensor, go to key-on or start the car. With the sensor disconnected the gauge should stay at 0 or the bottom of the scale.


If all those turn out normally, next we'll test the sensor. Disconnect the harness from the gauge, and reconnect it to the sensor. Measure voltage between the white wire (signal from sensor) and black wire (ground) and you should see a range between 0.5 to 4.5 volts. You will need to supply power and ground to the sensor while it's disconnected from the gauge. You can use short paperclip pieces if needed.
