5 Causes Of Low Engine Oil Pressure

August 28, 2014 By

Gasoline charges up a car’s engine and oil protects it. Think of oil as that shiny lubrication that protects the inner workings of the engine. If there is not sufficient oil the activity of the engine can cause overheating, and also cause the parts of an engine to wear down due to constant friction. If the car is suffering from low energy oil pressure, it means that there is insufficient oil lubrication being supplied. That can cause some very serious internal problems. There are a number of reasons why low oil pressure happens, and a car owner would be wise to keep them in mind.

1. There is not enough oil in the automobile.

Sign Of Low Oil Pressure

This seems almost too easy, but it is actually the biggest reason why there are oil pressure problems. Car owners will often forget about the oil and forget to have it checked. This should be part of any tune-up or inspection of the car. Besides being the most common reason, this also happens to be the easiest oil pressure problem to fix.
2. Engine wear

Like blood flowing through veins, oil follows a system of passages through the engine. Oil will pass move through the crankshaft bearings and the cam bearings of the car. If the clearance has been made wider because of these parts wearing down, oil easily flows through and that will reduce the oil pressure.
3. Trouble with the oil pressure gauge

Auto manufacturers will install oil pressure gauges in the car so that a car owner will know about the oil pressure in real time. It can happen that the car owner does not know that the oil pressure is low because of problems with the oil pressure gauge. The only way to be sure this is happening is to do a mechanical oil pressure reading.
4. Trouble with the filter
The oil filters play an important role in maintaining oil pressure. Should the filter get clogged it will reduce the pressure. The pressure relief valve of an oil filter is there to make sure the pressure does not get too high. However, if the relief valve is damaged, then oil will pass more freely in the engine, and that will reduce pressure.
5. The Viscosity of the Oil

This is the thickness of the oil being used in the car. Oil that has a high viscosity is going to be thicker and doesn’t flow as fast as oil with a lower level. This can affect the oil pressure depending on the time of year. It is quite possible that high viscosity will not allow oil pressure to build rapidly.
Fortunately, there’s some very easy ways to correct any problems with the oil pressure. It is already been mentioned that lack of sufficient oil can cause a problem. That is why a car owner should take the opportunity now and then to check the oil level in the car. Oil filters need to be maintained on a routine basis. This means every time the car is scheduled for any checkup, the oil filters are to be checked, just to be sure things are going smoothly. The owner may also want to consider using a low viscosity oil and have that placed in the system just prior to

Oil Filter Maintenance

winter. It is a good idea to have an auto mechanic do a mechanical oil pressure reading on the car. While the above reasons are symptoms of low oil pressure, there may be problems with the fuel pump, or other parts of the car. The mechanic can take a look at those possibilities if the reading is not satisfactory.
The real message to take away from home is the importance of routine maintenance on the car. This can be either by the owner or an automotive service center. Car owners will sometimes take things for granted and not address a problem until it becomes a major inconvenience. Oil pressure is something that can be routinely monitored without much effort. Honestly, it is better to note the problem and take care of it in the initial stages. Not addressing an oil pressure problem can result in serious difficulties developing within the engine block. Repairing problems there can be quite expensive. The cost can be easily avoided just by checking the oil level, and seeing to it that the pressure is at the right level.
