If the oil light on your Subaru Outback turns on, you have to be concerned. It suggests a potential failure that could damage your Subaru Outback or even put you in danger so be vigilant and very reactive.
In this article, we wish to try to provide you with an answer so that you can know the ins and outs of this sight and thus correct the situation.


What does the oil sight glass look like on your Subaru Outback?

To begin with, it is important to recognize this indicator on your Subaru Outback. 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 Subaru Outback as soon as possible. To ensure it works, you will see it turn on when you turn the ignition. If it does not light up, your indicator light is flawed.
Do not mix up this light with the almost identical yellow one. This one indicates that you are probably short of oil.

What is the purpose of the oil indicator light that lights up on your Subaru Outback?

Now, let us explain to you what it is for and why it is very important. As opposed to what we may think, it has nothing to do with the oil level in your Subaru Outback. Furthermore, it is there to report a loss of pressure in this engine oil, which can quickly damage or even ruin your Subaru Outback’s engine. That’s why as soon as it appears on your vehicle, you must stop the car.
then, we will explain to you what this oil is used for in your Subaru Outback’s engine. It works with a set of metal parts, which are regularly in contact and therefore need replacing. The oil under pressure consequently ensures the lubrication of these parts to stop them from being damaged. Otherwise, it also serves to cool them down because they heat up quickly when you drive your Subaru Outback. Finally, the oil also takes away and circulates dirt that could affect your engine.
You must consequently ensure that the engine oil pressure is always maintained at its recommended level for your Subaru Outback. This represents 1 bar at standstill and about 5 bars at high speed. In a logical way, when the pressure does not reach 1 bar, a sensor should signal it by lighting the warning light that should alert you.

Faults that trigger the ignition of the oil sight glass on your Subaru Outback:

Three factors could result in the ignition of this light. First, the most likely, if the oil pump is malfunctioning. It no longer fulfils its function of preserving oil pressure in the engine. If this is the case, we urge that you go to a garage because only a professional can make an appropriate diagnosis on your Subaru Outback.
Secondly, if you run out of oil, the pressure could drop. Same effect 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 more detect the pressure correctly and therefore transmits incorrect information. In this case, it is also necessary to call upon a professional for your Subaru Outback as he will have the pressure control device and will be qualified to tell you exactly what it is.

Conclusion :

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