Motorcraft filters are developed to Ford Motor Company’s high-quality requirements. They are recommended as the original equipment replacement filter for Ford, Lincoln, and Mercury cars. They protect against engine wear by removing abrasives such as carbon, sand, dust, and metal fragments before entering your oil.

Pressure-relief valves help to reduce the possibility of dirty oil circulating back into the engine. Also, it aids in sustaining the oil supply to the engine in extreme cold temperatures or when the filter becomes blocked. 

The exterior casings are steel, “ironed” for a tight fit, coated to avoid rust, and have flutings to facilitate removal. The efficient filter medium has a higher dirt-collecting capacity and may capture more engine-harming particles. 

Silicone anti-drain back valves help prevent oil from draining out of the filter and engine. In contrast, the engine is not operating and resists the aging effects that high heat may induce in engines. The fluted construction allows the unit to be compatible with several types of engines.


  • Maintain a proper supply of oil in extreme weather conditions
  • The silicone anti-drain back valves protect the oil from draining out of the engine and filter
  • The steel ironed outer casing offers resistance to rust

Buyer’s Guide for Best Diesel Oil Filter

This buyer’s guide will tell you the considerations you need to make when purchasing an oil filter.

Filter media

Inside each filter, a material handles the entire filtration process. The medium or material may be cellulose, synthetic, or a mixture of both. Synthetic ones often use polyester, glass, or nylon because of their tight woven construction. This structure provides better filtering efficiency. Synthetic media can capture even the most minor impurities without affecting the flow rate of the oil.

Besides there, cellulose media is a more affordable option. However, its price is a bit high. Many buyers use combined means because they offer a reasonable price and functionality.


The capacity of the oil filter represents the product’s ability to retain contaminants. Two main factors affect the strength of an oil filter: construction and media. More power means better and longer mileage.
When the filter reaches its maximum capacity, it cannot perform filtration. The device will then allow unfiltered oil to enter the car’s system.

Easy to use

Oil refining on the market is not the same; available in different shapes and sizes, and not all filters are suitable for your vehicle. Choosing an oil filter compatible with your car should also have a simple installation process.

Design and construction

Any filter should provide durability and value for money. Each vehicle follows a different specification; the weight and design of the filter determine its compatibility with your car. You must ensure that the filter complements the structure of your vehicle.

You can read the manufacturer’s manual to determine filter weight and design requirements to understand the best fit; it would help if you looked for a filter with a coating. That is great for reducing rust and corrosion.

Frequently asked questions (FAQ)

The Difference With A diesel Oil Filter

Oil filters replaced for automobiles are usually significantly more significant than the originals. Because diesel engines are built, oil filters must be changed more frequently than gasoline-powered vehicles. Ensure good filtration under all operating conditions; some trucks have two separate oil filters: a full-flow filter and a bypass filter. On the other hand, manufacturers of diesel engines have made significant progress in developing techniques to improve the quality of their machines. A slight drawback is that diesel engines are dirtier and more difficult to maintain than gasoline ones.

Are All Oil Filters Compatible With All Vehicles?

To be sure, double-check with the manufacturer of your vehicle, although most automotive filters manufactured for modern automobiles can handle any oil. Every major motor oil producer claims that you don’t require a unique or specialized oil filter when using synthetic oil.

What Is The Best Oil Filter For A Duramax?

What happens if you change the oil but not the oil filter in this case? Suppose your oil filter isn’t replaced regularly. In that case, it can become significantly blocked, limiting the amount of oil that passes through it and into your engine. 

Is It Necessary To Change Oil Filters Regularly?

According to car manufacturers, oil filters should be changed every time you get your oil changed. On the other hand, most parts and oil manufacturers recommend that oil filters be replaced every 3,000 miles or three months (whichever comes first).

Are Aftermarket Oil Filters As Good As OEM? 

You may rest assured that all OEM oil filter housing is well-sealed and well-constructed. Aftermarket oil filters do not come with the same guarantee. The oil filter’s design and construction are left to the discretion of the aftermarket maker.


The quality of your oil filter can have a significant impact on the performance of your engine. Choosing a dependable oil filter might be difficult with so many alternatives. You cannot be satisfied with only selecting a good oil filter. When changing the oil, it is also critical to replace the oil filter. This will ensure that your engine continues to run smoothly for a long time. Any of the 10 Best Diesel Oil Filter listed above are excellent buys that will work wonders on your vehicle if they are the perfect fit.
