Oil filters play a crucial role in your car engine's performance and longevity. The small, inexpensive filter might not seem like much, but it actually does an important job. Oil filters help provide the clean lubrication your engine needs to keep your car on the road.
But not all oil filter brands are made the same. There are a variety of brands on the market, each with its own vehicle specifications and filter efficiency. It is smart to know which available oil filter brand is best suited for the car you drive. 
If you’re looking for the best oil filter brand, here are a few options to consider for your car maintenance routine.
Oil filters are important for the longevity of your car, because they help remove contaminants.
FRAM is one of the best oil filter brands. The company’s oil filters are easily recognizable in auto parts stores because of their iconic signature orange finish. 
These oil filters are a popular choice, offering drivers a satisfying balance of affordability and performance. The FRAM Extra Guard Oil Filter traps 95% of oil contaminants with a unique blend of fibers and resin.
Installation of the Extra Guard is a snap. The oil filter's "Sure-Grip" feature uses a special textured coating designed to prevent sliding when being installed. If you use conventional oil in your car, you can expect 5,000-mile engine protection. Synthetic oil users can see up to a whopping 10,000 miles.

Bosch Premium FilTech Oil Filter lives up to its name

Bosch is one of the leading brands of quality automotive parts in the industry. Its oil filters are no exception. 
The Bosch Premium Filtech blends synthetic and natural materials to efficiently filter out an impressive 99.9% of contaminants. The filtration system is even able to capture particles as small as 20 microns and store 14 grams of contaminants.
A metal spiral-wound center tube improves the filter's internal strength and contributes to its durability. The Bosch FilTech protects your engine from leaked contaminants with its specially-designed end caps. There is also a built-in oil relief valve to ensure the proper oil flow is applied. A lubricating sealing gasket allows for a better fit.

Is Mobil 1 Extended Performance the best oil filter brand?

When it comes to your car's lubrication system, the Mobil 1 brand has proven its mettle throughout the years. The Mobil 1 Extended Performance oil filter's synthetic fiber blend offers an excellent 99.6% filtering efficiency. Its design holds up to 28 grams of debris and particles.
Top Speed notes that this filter stands out for its ability to last longer than any other oil filter due to its synthetic nature. Most auto mechanics suggest oil filters be changed at 5,000 miles. Mobil 1 Extended Performance, on the other hand, is good for 15,000 miles when using synthetic motor oil. The filter's anti-drain back valve also helps prevent dry starts.

K&N Performance Wrench-Off Oil Filter is trusted for its durability

K&N oil filters are specifically developed for high-performance vehicles with a higher flow rate. Certain models of popular car brands, including Subaru, Nissan, and Mazda, benefit more from the filter's durable filtration capacity. Its pleated synthetic blend is 99% efficient and is ideal for high-speed situations.
The K&N Performance Wrench-Off oil filter is compatible with conventional, blended, and synthetic oil. It is most appreciated for its sturdy construction and durability. Like the Mobil 1 filter, the K&N can withstand longer intervals between routine maintenance changes. 
The filter comes with a one-year limited warranty, helping it to take its place among the industry's best oil filter brands.
