There is a light on the hood of the car that says "oil pressure low, stop engine."

Low oil pressure is one of the most serious issues that can happen to your car's engine.The engine will seize up if the oil pressure is low.It should be assumed that the engine is about to lock up when the oil pressure light on.Don't run the engine until the issue can be diagnosed.

A lack of oil is the number one reason that your car has low oil pressure.Check your engine oil level is the first thing you should do.

If the engine oil level appears to be empty, you need to fill it up.Don't drive a vehicle with low engine oil to the store.The engine will look up if there is not enough oil in the crank case.It is only a matter of when it will lock up the engine.

The oil pump takes the oil from the pan and pumps it through the engine.It will no longer be able to pump oil when it wears out.

There is a screen in most oil pumps.There will eventually be enough debris in the pump to cause some damage.

Air can get into the oil pump if it's lower than it should be.Think about the foam on a beverage.It is the same liquid, but has different characteristics when foamy.

This can happen when there is too much oil.Make sure the oil level is ok and that it looks okay.

Engines that run long enough without a regular oil change schedule can get so dirty on the inside that it starts to build up inside the crank case.The dirty oil could cause low oil pressure because it no longer cycles through the engine properly.

If you don't know when the last oil change is or if you have done a lot of towing, changing the oil can solve the problem.

There is a tube in your car that takes the oil from the pan to the pump.The pickup tube is what it is.No oil will get to the oil pump if the tube falls out.

When the filter is clogged, modern engines use a bypass valve to keep oil flowing to the engine.When there is too much resistance from the oil filter, the bypass valve is activated.The oil light may be triggered by this valve, which only allows so much oil through.

Checking the oil level in your car is the best place to start looking for low oil pressure.If the oil level is low, you need to fill it up.The problem may be solved by this.

If the oil leaks out once, it will leak out again.You will need to check it more often.

Electric oil pressure sending units are used in modern vehicles.The sensor on your car will shoot a false low pressure reading if it goes bad.One of the first things that people do when they have a low oil pressure light is to change out the sensor.
