The oil filter is one of the most important components of the car because it protects the engine and increases fuel efficiency. Its primary function is to remove contaminants or other particles found in motor oil that can cause significant damage on essential engine parts.
Ideally, oil filters are replaced after driving approximately 3,000 miles.
There are three common types of vehicle oil filters:
Primary oil filter. This is the standard oil filter used in most cars. It’s designed in such a way that all engine oil naturally goes through it during the normal operation of the car. One of its advantages is the ability to filter large amounts of motor oil and still allow oil to flow freely even during cold temperatures.
Secondary oil filter. This type of oil filter is mostly found on diesel engines. Also mostly installed on gasoline engines, this oil filter takes a certain amount of the oil into the second filter so it can be cleaned further. This helps lengthen the life expectancy of the engine and likewise increases time between motor oil changes.
Magnetic oil filter. By the name itself, the filter has a tiny magnet inside its canister that easily catches small pieces of rust and metal. This prevents harmful particles from circulating throughout the engine. Aside from being positioned inside, the magnet may also be put outside depending on the model.
Here are the other things you should consider when buying an oil filter:
Determine the Size of the Oil Filter
You probably have seen several engine oil filters and they look almost exactly the same. However, taking a close look on each one of them would tell you that they’re actually different in various ways.
Some cheaper brands use cellulose fibers, while mid-range-priced oil filters utilize both cellulose and synthetic fibers. On the other hand, the more expensive brands use specially-made microglass fibers for superior oil filtration.
Other things to look at are the part number and the size of the oil filter. Make sure your replacement oil filter fits perfectly. You’ll know it because it gets seated properly when installed.
If you’re not sure, read your car’s user manual for the right size and the type of motor oil filter that may be installed. In some cars, the part number may be found at the bottom edge of the oil filter.
Inspect Properly the Oil Filter
Choose an oil filter that has an anti-drain back valve as it ensures the availability of oil upon engine cranking in spite of cold temperature.
Also, choose a filter with a by-pass valve. This guarantees the proper flow of oil to vital engine components despite major blockage due to some impurities.
Moreover, heavier filters have more filter medium available in its housing. On the other hand, lighter filters can easily get clogged up, thus their risk of damaging your car’s engine is high.
There are a couple of oil filters available today and they range from cheaper brands to premium models. Determine the right oil filter to buy by reviewing your car’s specifications, make and model, and the year it was released.
