Oil Pressure Gauges

How It Works

GlowShift’s Oil Pressure Gauges are electronically driven and use a 1/8-27 NPT electronic oil pressure sensor. The sensor can be installed directly to the oil gallery, an oil gallery test port, an oil filter sandwich adapter and an oil cooler adapter as well. A T-Fitting can also be used by attaching it to the included oil pressure sensor or the factory sensor. Installation will vary by application and may require additional threading adapters.

Why It’s Important

Let’s think of Oil Pressure as the blood to your engine. It works to keep all of your mechanical parts properly lubricated. Maintaining proper lubrication reduces the wear on your engine’s parts to ensure the engine does not get too hot and continues to run smoothly. A lack of oil pressure can be catastrophic to your engine and having a reliable oil pressure gauge installed allows you to know your precise pressure to help avoid any problems. An oil pressure gauge can also help indicate when it is time for an oil change on some vehicles.

High Pressure vs. Low Pressure

Ideally, you want your oil pressure reading to be at a median level. A high pressure reading is generally 80 PSI or over while driving at higher RPMs. This may vary by vehicle and each owner should verify the specifics in their vehicle manual. High Oil Pressure occurs when an unusually high amount of pressure is needed to circulate oil through the engine. A few common causes of high oil pressure can be a bad pressure relief valve, blockage in the oil delivery lines, or a malfunctioning oil pump that restricts the flow of oil. A low oil pressure reading is generally below 15 to 20 PSI while idling. A low reading can occur in cold weather where the oil pump may take a little longer to deliver the oil to the engine. Other common causes of low oil pressure can be worn bearings, a broken oil pump or the need for an oil change. Keep in mind that oil pressure gauges may display lower or higher readings in cold weather due to the viscosity of the oil or the oil pump being delayed in delivering oil to the engine. If your gauge is reading high or low oil pressure, be sure to get it checked as soon as possible as this can quickly lead to engine failure.
