Everyone who drives a car should be aware how oil makes their car run safely and efficiently, and the important functions it fulfills inside the engine. Observing the oil pressure gauge is critical. As soon as there is a problem with the oil you need to be aware of it immediately and is gauge is how you know. As the name suggests a mechanical oil pressure gauge tells you the pressure the oil is operating inside the engine. It does not tell you the amount of oil inside the engine although the pressure is affected by this.

If the pressure drops oil cannot do its work. It cannot lubricate because it has reduced resistance to the forces trying to sweeping aside as the moving parts go backwards and forwards. It cannot circulate quickly enough to help cool the engine so the oil gets super hot before it is returned to the oil sump where it is called by the passage of air beneath the car. If the oil pressure gauge lamp comes on let the engine cooled down and then check the oil level. You should do this on a regular basis as part of your car maintenance routine. If you have to topple the level do it carefully you do not want to have too much oil in the engine and it is much easier to add more little by little than it is to drain oil away by opening the oil pan.

Factors that affect oil pressure include the amount of oil in the engine, the age of the oil and the oil filter and the oil pump. Whenever you change your car oil you should also change the filter to.
