Oil pressure gauges serve an important function in being an early warning system for the vehicle. You will be able to get an idea of the well-being of the engine and it can also indicate certain issues of the vehicle at an early stage so that you can attend to them before the vehicle breaks down requiring you to pay for expensive repairs.
You have to understand the motor oil types available and what is recommended for your car. There are recommended intervals for changing engine oil. And most importantly, you need to understand how to read the oil pressure gauge of the car. This is what monitors the oil pressure in your vehicle and you will be able to see how much oil is available in the fuel tank. You can get an idea of the health of the engine as this gauge can indicate oil pump failure, a leaking gasket or a broken hose. There are mechanical and electrical gauges. Electrical gauges have a sensor. The needle in a mechanical oil gauge is forced up by the pressure from the vehicle engine.
Electric gauges are common in modern cars and they are powered by the electrical wires located behind the dashboard. The resistance of the return wire of the gauge is measured when a current flows through a coil. This resistance shows oil pressure. You can easily integrate an electric gauge into a modern circuit making installation easy. There are pipes in mechanical gauges and some consider mechanical gauges to be more accurate. However, if there is a puncture in the oil pump, it can eject engine oil at engine pressure which can be hazardous. Therefore, more maintenance is required for mechanical gauges than electric ones.
When it comes to choosing between electric and mechanical pressure gauges, electric gauges are easier to integrate and are more compact. You can easily connect it to the vehicle. While mechanical gauges are not common, you can still find them in certain stores. It all depends on whether you can balance high accuracy with high maintenance. When you start driving a vehicle, it is very important that you learn how to read what is on the dashboard along with the warning indicators. Not all oil gauges will look the same. Some have numbers and some use letters. In the latter method, “L” is used to indicate low pressure and “H” is used to indicate high pressure.
There is a dashboard light that will come in when there is a change in oil pressure. Some vehicles will not have this feature. The owner’s manual in your vehicle will let you know how to correctly read the oil gauge. You will generally see a zero reading when you are idling. But if you see this when you are going at a higher speed, this will indicate a faulty gauge, a broken oil pump or a low oil level. Whenever you see this, you need to park in a safe area and switch the engine off so that it can get checked out.
