Purolator Oil Filter Problems: The Design Issue Back In 2013

Every Purolator oil filter user leaves negative feedback on different forums based on their experience. We found the oil coming from around the oil filter seal once we started the engine. 

So, we drain the oil and pull the filter out. When we inspected the oil filter thoroughly, we found some witness marks where the oil filter came in contact with the recessed nut. You can find this nut on the oil filter shaft inside the motor. 

We clearly explore that the top surface of the filter comes in a convex shape. Therefore, the gasket on the top surfaces is too wide. As a result, oil leaks around the gasket line with ease. Indeed, the Purolator oil filter has a serious design issue that is responsible for an oil leak. 

Therefore, the media filter this oil filter incorporates is made of paper elements. If you want to use the oil filter for several hundred miles, go for the oil filter synthetic media. 

However, if you want to get better results from the Purolator oil filter, we recommend you take a look at the design of the top surfaces. Make sure you choose the Purolator oil filter with concave shape top surfaces, not the convex one.

Is There A Such Thing As A Defective Oil Filter?

Like all mechanical or electric equipment, the oil filter can also go bad. If the oil filter gets defective, it fails to adjust to the changes in temperature within the engine. In the worst case, the oil filter may rupture or burst. Consequently, the oil will leak back into the oil pan. 

Now, you may ask- how can I understand when the oil filter gets defective? Well, notice the following symptoms that will tell you about a malfunctioned or bad oil filter. 

  • If the oil filter gets clogged or defective, the car struggles to release oil into the engine. It may create a speed issue for your car and your car will sputter. 
  • You can hear a grinding noise as the oil leaks out before lubricating the moving metal parts. 
  • The oil pressure gauge reading will also drop down dramatically if the oil filter goes bad. 
  • The exhaust will get dirty which will indicate the oil filter gets defective or there is a problem with the oil system. 

As soon as you observe these issues, you must change the oil filter. Otherwise, it will bring ultimate engine destruction, which will leave a dent in your wallet.
