If the oil light on your Mazda 5 lights up, you have to be concerned. It suggests a potential failure that could affect your Mazda 5 or even put you in danger so be careful and very reactive.
In this article, we want to try to provide you with an answer so that you can understand the ins and outs of this sight and thus correct the situation.


What does the oil sight glass look like on your Mazda 5?

To begin with, it is important to identify this indicator on your Mazda 5. It is red in colour and represents a small burette with a drop on the right. Like all red lights, this means that you must stop your Mazda 5 as soon as possible. To check it works, you will see it turn on when you turn the ignition. If it does not light up, your indicator light is broken.
Do not confuse this light with the almost identical yellow one. This one indicates that you are almost certainly short of oil.

What is the purpose of the oil indicator light that lights up on your Mazda 5?

Now, we want to explain to you what it is for and why it is vital. Unlike what we may think, it has nothing to do with the oil level in your Mazda 5. In addition, it is there to report a loss of pressure in this engine oil, which can quickly damage or even ruin your Mazda 5’s engine. That’s why as soon as it appears on your vehicle, you must stop the car.
then, we will make clear to you what this oil is used for in your Mazda 5’s engine. It works with a set of metal parts, which are constantly in contact and therefore need replacing. The oil under pressure therefore ensures the lubrication of these parts to stop them from being damaged. Otherwise, it also serves to cool them down since they heat up quickly when you drive your Mazda 5. Finally, the oil also cleans and circulates dirt that could damage your engine.
You must therefore ensure that the engine oil pressure is always maintained at its recommended level for your Mazda 5. This represents 1 bar at standstill and about 5 bars at high speed. Logically, when the pressure does not reach 1 bar, a sensor should indicate it by lighting the warning light that should alert you.

Faults that trigger the ignition of the oil sight glass on your Mazda 5:

Three factors could lead to the ignition of this light. First, the most likely, if the oil pump is faulty. It no longer fulfils its function of preserving oil pressure in the engine. If this is the case, we would suggest that you go to a garage because only a professional can make an appropriate diagnosis on your Mazda 5.
Secondly, if you run out of oil, the pressure could drop. Same consequence with low pressure, the red LED lights up. So what you have to do is add more oil. The last, rarer case is a flawed pressure sensor that can no longer detect the pressure correctly and therefore sends incorrect information. In this case, it is also necessary to call upon a professional for your Mazda 5 as he will have the pressure control device and will have the ability tell you exactly what it is.

Conclusion :

So now you know what this light is for and what the related failures are on your Mazda 5. Once again, be extremely cautious when a red light comes on as they represent a real immediate danger to your Mazda 5 and especially to passengers.
