Oil pressure indicators on cars are split into two categories. Cars come equipped with pressure gauges that indicate the level of pressure. Other cars feature only a dash light that comes on when the oil pressure falls below a set level. Each indicator has advantages depending on your personal preference and level of automotive repair knowledge.
Oil pressure gauges offer more information.
The dial on these devices show the precise amount of oil pressure being detected by your vehicles oil pressure sending unit. You can tell if the pressure is a little high or a little low or if there is a serious oil pressure problem developing. Unfortunately, if you are not educated about what various changes in oil pressure can indicate, this information may be of little use.
Seeing the oil pressure gauge drop below the normal mark can cause a panic.
Those who are untrained regarding oil pressure may view brief dips in oil pressure as a catastrophe getting ready to happen. The reality is that oil pressure is often related to engine revolutions per minute. While your car engine is designed to compensate, a quick drop in revolutions per minute can cause the oil pressure to need a moment or two to compensate.
A pressure gauge can signal a building problem before a light indicator.
Consistently low oil pressure may point toward low oil, weak seals, main bearing issues, or a failing oil pump. By catching these types of problems early, you may be able to have smaller problems fixed before they can cause more extensive engine damage. Oil pressure tests are not usually something performed during routine servicing of your car.
The oil pressure warning light can be a great benefit for less mechanically inclined drivers.
These lights are bright and should catch your eye shortly after they light up. Unlike a pressure gauge that you might tune out while driving, the light is an immediate change in front of the driver’s eyes. The likelihood of most drivers catching immediate oil pressure problems quicker is increased.
When the oil pressure light comes on, it indicates a potential serious issue.
The light should remove the guess work from whether or not the vehicle has a serious oil pressure problem. If your oil light is off, you can relax. If the light comes on, you need to act immediately. When this light is on, it is best to stop driving the car as soon as possible. The only indicator that matches this on a pressure gauge would be when the dial falls to zero.
People who like to feel that they are in touch with the pulse of the car will prefer gauges.
The gauge lets you monitor your car’s engine in real time and make your own choices about engine oil pressure issues. The light indicator can leave you running in the dark until a problem reaches a near critical level. If you believe ignorance is bliss, you will like the lights.
