Keep Your Car Engine in Tip-top Shape with a Genuine Oil Filter

The main function of an oil filter is to remove particles and contaminants from your engine oil that accumulate over time. Failing to strain these hardened particles can result in the wearing down of a car’s oil pump and the engine’s surface bearing.

While several contaminants can enter the engine oil, silica is considered the most destructive to engine surfaces. This is why choosing an oil filter is just as important as replacing them when needed.

Do not skimp on this part as you’ll only end up shelling out more money in the long run when the debris severely damages the engine. Most cheaper oil filters tend to have rubber gaskets and rubber anti-drain back valve. Premium oil filters, on the other hand, use silicone for both parts, which perform better and longer. 

It’s advisable to replace your oil filter when it hits the 7,500 mileage mark or every time your vehicle is due for an oil change. But it’s best to consult your manufacturer’s handbook just to be sure. There are several conditions to consider, as well.

Extreme temperature, constantly carrying heavy loads, and the quality of the road you’re usually driving on are the most important aspects to watch out for. If any of these apply to you, then you may need to replace your oil filter more frequently.
