What is an Oil Pressure Gauge?

An oil pressure gauge measures the oil pressure in your engine. It’s typically found on the dashboard of your car. Your oil pressure gauge informs you of how much oil remains in your vehicle, but it’s also an indicator of your engine’s general health. If you notice your car has low oil pressure, we recommend having a qualified technician inspect it. Low oil pressure can be indicative of various problems, including:

  • An oil pump failure
  • A broken hose
  • A leaking gasket

How Do I Read My Chevy’s Oil Pressure Gauge?

Check your vehicle’s dashboard to locate your oil pressure gauge. Your oil pressure gauge will typically have a distinct label, such as “oil.” Some oil pressure gauges display numbers ranging from 1 – 80 or 1 – 100 via a digital display or an indicator needle. However, your car may keep things simple with an “H” to indicate high oil pressure or an “L” for low oil pressure. To get the most accurate results, we recommend establishing a baseline reading on your oil pressure gauge after you’ve had a tune-up and oil change. This number can be considered your vehicle’s healthy standard.

What are the Different Types of Oil Pressure Gauges?

There two types of oil pressure gauges are electric and mechanical:

  • Electric gauges: The majority of modern cars use electric oil pressure gauges. They send an eclectic current through a coil and measure resistance in the instrument’s return wire. The amount of resistance corresponds to your car’s oil pressure. Electric gauges are easier to install than their mechanical counterparts and aren’t subject to the same wear and tear.
  • Mechanical gauges: Mechanical oil pressure gauges use a small tube called a pressure line to connect the engine’s oil system to a gauge inside the vehicle. The gauge typically consists of a dial and a pointer, which indicates the oil pressure reading. Mechanical gauges require attention and maintenance to avoid punctures in the oil pipe, potentially causing oil to spew at engine pressure.

Your Chevy’s oil temperature and oil pressure light relate to the engine oil system. As its name suggests, the oil temperature light can alert you when your engine oil’s temperature is too high. This issue has various causes, including low oil levels, a malfunctioning oil pump, or a clogged oil filter. If you notice your oil temperature light is one, it’s essential to take immediate action to prevent potential engine damage from overheating or a lack of lubrication.
