6 Signs You Need To Change Your Oil Filter

The oil filter is responsible to keep dirt and contamination with external dust and materials away from your engine oil.

The oil filter ensures that the engine oil is clean. It is obvious that the cleaner your engine oil is, the better performance of your car.

As the oil filter works on cleaning the lubricating oil for your engine, it accumulates dust and dirt, and other impurities, which makes it less efficient.

So, it is essential that you keep a check for some signs that mean you should immediately check/replace the oil filter for your car.

Before we dive into the signs, let us discuss the risk involved in ignoring the change of oil filter.

What happens if you don’t change your car’s oil filter in the due time?

It just means that you’re taking a big risk with your car. If your oil filter is clogged, this will impair the functioning of engine oil. And, engine oil or engine lubricant does not get to function as it should. This could damage your engine, costing you a lot more than what it would cost in replacing the oil filter.

It is highly recommended that you use good quality engine oil for your car.

Let us now discuss the signs of clogged oil filters or signs that tell you to change your old filter.
