Best Oil Filter on the Market

 An oil filter to an engine is like the liver to the body – it is designed to remove contaminants from your car engine’s oil that can accumulate over time and keep your engine clean. Clean motor oil is important to keep your engine running at optimal condition for as long as possible. If oil is left unfiltered, tiny, hard particles can accumulate in the oil that can cause wear-and-tear to the surface of the engine and wear the oil pump’s machined components down.

Types of Oil Filters

There are many different types of oil filters on the market, but all are designed with a common function: to keep the engine of a vehicle clean from contaminants. They play a crucial role by purifying the oil of the engine that has to collect contaminants before it runs through the engine.

The type of oil filter that is best suited for your vehicle will depend on the engine type and the recommendations made by the auto manufacturer. Here are some common types of oil filters and how they differ.

1. Full-Flow Oil Filter

A full-flow oil filter is the commonly used oil filter by car manufacturers. Also known as a primary oil filter, a full-flow filter is designed to remove contaminants and impurities from all of the oil used by a car’s engine.

These types of oil filters are especially useful in colder temperatures as low temps can cause motor oil to thicken and a full-flow filter allows the motor oil to move more freely through the engine, thus allowing for full performance and preventing damage to the engine when the mercury drops.

2. Secondary Oil Filter

A secondary oil filter is used alongside the primary oil filter to support the vehicle’s full-flow filter and is designed to remove contaminants that may have been missed by the full-flow filter. Although they clean less than 10% of the motor oil used by the engine, they are an extra measure used to provide additional protection for the engine.

3. Cartridge Oil Filter

A cartridge oil filter is another type of full-flow oil filter that does not have any metal parts. Usually mounted upright, a cartridge oil filter is easy to use and can be inspected without needing to remove the oil. Cartridge oil filters are also easier to recycle than other oil filters due to having no metal parts.

4. Spin-on Oil Filter

A spin-on oil filter is another kind of full-flow oil filter that features a steel canister paired with a paper element. Spin-on oil filters are usually tailor-made for hobbyists and DIYers and installation is simple and easy.

5. Spinner Oil Filter

A spinner oil filter is a type of secondary oil filter that uses centrifugal force to trap contaminants in the vehicle’s motor oil. Some spinner oil filters can generate forces more than 2,000 times greater than that of gravity, allowing them to efficiently remove the tiniest contaminants from motor oil.

6. Magnetic Oil Filter

A magnetic filter is another type of secondary oil filter that is used in conjunction with a full-flow filter. These types of secondary filters work well as cleaning and removing metallic contaminants from motor oil, and do not need to be removed, however do need to be cleaned regularly.

How to Choose the Right Oil Filter for Your Car

Choosing the correct oil filter for your vehicle is essential if you want your engine to perform at optimal levels. Using the wrong filter can cause oil to leak out of the engine, causing serious engine damage in the long run. The best way to determine which oil filter you need is to consult the owner’s manual for your car, reference a catalog of parts for the model of your car, or ask a reputable mechanic.

Filtration Media 

Inside every oil filter is a material that acts as the filter and catches the contaminants in the oil. Also known as the media, the material can be a blend of cloth, cellulose, or synthetic.

Synthetic media is one of the best materials to use as it is made from a blend of polyester, glass, or nylon and boasts a tightly woven structure that is a highly efficient filter. This tightly woven structure can catch even the tiniest impurities without compromising the oil flow rate and resulting in better filtration efficiency.

Cellulose media is a more affordable option than synthetic media, however, it does not have the same efficacy as synthetic media.

Capacity 

The capacity of an oil filter is the product’s ability to catch and retain contaminants in the oil. More capacity means better and longer mileage. When the filter reaches the maximum capacity, it cannot carry out the filtration process. Two factors affect the oil filter’s power – the build and the media. More capacity means better and longer mileage.  

Ease of Use 

Oil filters are available in a wide range of shapes and sizes and have varying filtration efficacies. Not all oil filters are alike and do not fit into all vehicle types. When you are choosing an oil filter, you need to make sure it is compatible with the model and make of your vehicle.

Design and Construction 

The design, construction, and weight of the oil filter will determine its compatibility with your vehicle, and it is important to ensure that the filter complements the structure of your vehicle. The owner’s manual of your vehicle is the best place to find out what type of oil filter is best for your automobile.

Frequently Asked Questions

  1. How do oil filters work?

The outside of the filter is a metal can with a sealing gasket that allows it to be tightly held against the engine’s mating surface. The base plate of the can holds the gasket and is perforated with holes around the area just inside the gasket. 

A central hole is threaded to mate with the oil filter assembly on the engine block. Inside the can is the filter material, most frequently made from synthetic fiber. The engine’s oil pump moves the oil directly to the filter, where it enters from the holes in the perimeter of the base plate. The dirty oil is passed (pushed under pressure) through the filter media and back through the central hole, where it re-enters the engine (Mobil.com).

  1. What is the best oil filter removal tool?

When it comes to removing the oil filter, the best tool to use is the GEARWRENCH Heavy-Duty Oil Filter Wrench. This high-end tool can remove an oil filter without making holes in it and creating an oily mess.

  1. What is the best type of motor oil to use?

Royal Purple and Mobil 1 Oil are the two leading brands of synthetic motor oil in the world. Royal Purple is a High-Performance Synthetic Motor Oil and Mobil 1 is an Annual Protection Ultimate Full Synthetic Oil. Synthetic oils are lubricants made from artificially made chemical compounds using chemically modified petroleum components rather than whole crude oil.

Produced by trusted brand names, both oils are high-performance synthetic oils that only need to be changed once a year. When it comes to deciding which oil is better, Royal Purple and Mobil 1 Oil have slight differences in their formulations, but the main difference between the two oils depends on how and where the oils will be used.

Is Mobil 1 better than Royal Purple?

The jury is out on whether Mobil 1 Oil is better than Royal Purple as both have excellent qualities and provide premium engine protection for a wide range of vehicle engines. Selecting the best synthetic oil will depend on what you want to use the oil for and whether you are looking for superior protection for your engine or high performance.

Mobil 1 and Royal Purple Oil are very similar products – both are high-quality synthetic oils that boost the performance of the engine by removing deposits from the engine, prolonging its lifespan, and improving driving quality. The best way to decide whether Mobil 1 is better than Royal Purple is to draw up a list of pros and cons for each oil and then make a decision.

Let’s take a more in-depth look at each of these synthetic oils and their pros and cons.

Royal Purple Synthetic Oil

Royal Purple is a high-performance synthetic oil that is produced by a company in the United States of America that specializes in auto marine, industrial, and racing lubricants.
