Best Oil Filter Buying Guide

Types

  • Mechanical – Mechanical oil filters use materials such as pleated cotton and filter paper to prevent impurities in the oil from breaking through. With time and more dirt in the filtering material, they minimize the oil flow;
  • Cartridge – Cartridge oil filters have a basic design that hasn’t changed a lot over time. They include a housing case with a filtering media that you have to replace from time to time. Recent design improvements added a spin-on to improve the filtering capabilities. The filtering media is built from a synthetic material, paper, cotton, or cardboard found in mechanical oil filters;
  • Magnetic – Since most of the debris and impurities in oil are small metal components, a magnet can draw them out of the oil as it passes into the motor. They apply either a magnet or an electromagnet to purify the oil on the go. It makes cleaning the oil filter as easy as taking contaminants off the magnet;
  • Sedimentation – Sedimentation oil filters pull the debris down to the bottom of the filter. Since the debris is heavier than the oil, the filter relies on gravity to do all. To some extent, sedimentation works in cleaning the oil. Still, It’s not the most reliable way to eliminate contaminants from the oil. With the oil’s speed and pressure, many contaminants escape the pull of gravity and enter the engine;
  • Centrifugal – Oil filters that utilize the centrifugal force have a design that allows the oil rotates inside the housing at high speed. The oil goes out while the impurities get stuck to the walls of the housing.

Main Features

  • Capacity – The oil filter capacity demonstrates its ability to hold the contaminants it collects from the oil with no need to replace it. Two elements affect the filter’s capacity – the media type and the build of the filter. Capacity means better mileage. When a filter hits its capacity, it’ll let unfiltered oil into the engine via the dump valve;
  • Filtration media type – Inside every oil filter, there’s a material that actually performs the filtering of the oil. That material, called media, is made of synthetic, cellulose, or a combination of those two. Synthetic type is usually made from polyester, glass, or Nylon and has a better filtration capacity due to the high quality of the tightly woven fibers. It can capture the tiniest impurities in the fluid without affecting the oil’s flow rates. Cellulose is less expensive than synthetic media but has a lower quality. Blend media is a better choice both in cost and performance;
  • Design of housing – The lack of standards in the car industry means every brand and model has its own specifications. Its weight and housing design determine whether an oil filter can be installed in a specific car or not. Ensure the filter’s specifications match your vehicle’s requirements outlined in the owner’s manual.
  • Ease of use – Filters come in different sizes and shapes. Not every filter will fit into your car. When you select the one that’s designed for your car, it should be easy to install without problems;

Who Makes the Best Oil Filters?

Below are the three best oil filter brands on the planet. They are the best selling and most trusted brands with several million sold products in the US.

  • Mobil 1 – ExxonMobil is the corporation behind Mobil 1. Around 135 years ago, the firm started as a local kerosene seller on the U.S. market. Now, it’s one of the largest oil and petrochemical enterprises in the world. Best oil filters in its lineup are the Mobil 1 M1-110 Extended Performance Oil Filter and Mobil 1 M1-113 Extended Performance Oil Filter;
  • Motorcraft – Motorcraft was launched in 1972 to provide spare parts for Ford Motor Company. As we said, it manufactures car parts for Ford, Lincoln, and Mercury vehicles. The oil filter made by this brand fits into many car models and makes. Top products are the Motorcraft FL820S Oil Filter and Motorcraft FL-500S Oil Filter;
  • Bosch – In 1887, Robert Bosch invented a magneto ignition device for an engine. 10 years later, this genius installed the device in a three-wheeled vehicle, and the rest is history. Today, the Bosch Group has facilities all over the world and employs around 400,000 people. Top products include the Bosch 3330 Premium FILTECH Oil Filter and Bosch 3410 Premium FILTECH Oil Filter.

Why Invest in Good Oil Filter?

  • Extends engine lifespan – The motor needs clean oil circulating inside it to run at top performance. A high-quality oil filter keeps the dirt and other contaminants in the oil from reaching the engine’s internal parts. This prolongs both the engine’s life and power;
  • Guards against oil oxidation – No matter how bad or good the road conditions you drive in are, car oil oxidizes during the time. The oxidation brings in even more contaminants to the oil and reduces its efficiency. A filter screens out these contaminants from making their way inside the engine and guards the motor against damage;
  • Prevents engine heat spike – Overheating of the engine is a common issue caused by low-quality oil. The buildup of impurities and dirt in the oil can wear down the engine and kill heat conductivity. The oil filter keeps the engine components lubricated with pure oil and prevents engine overheating.

Cost

  • Less than $10 – Oil filters at this price tag aren’t the finest quality. You have to change this type of filter more often than other alternatives that cost more. The poor quality can end up costing more in engine servicing and repairing in the long term;
  • $10 – $15 – On average, good-quality filters sell in this range. These products utilize good filtration materials, so you don’t have to change them so often;
  • Over $15 – An oil filter in this price range will likely have all the attractive features. According to their functionality, the valves are made from silicone or steel to withstand high temperatures and pressures.

What are the Warning Signs of a Bad Oil Filter?

  • Oil leaks: If you notice that the oil drips from the car, it means you may have problems in the system.
  • Engine check light: if the contaminated oil enters the engine, it may build up in the system inside, causing an array of malfunctions. Such actions will trigger the engine light.
  • Overheating: The contaminant buildup may affect the heat conductivity of the engine, resulting in high temperatures and overheating. As a result, you may notice unusual sounds that call for the engine inspection.
  • Difficult to start: You may experience an array of starting issues resulting from inconsistent fuel flow. It happens when the fuel filter has not been changed for a while.
  • Frequent stalling: If your car stalls frequently while driving, you might have problems with a dirty and clogged fuel filter.

FAQ

Where is the Oil Filter?

To find the oil filter, look at the top, bottom, and engine sides. It is attached to an outlet that’s coming from the engine block, and it is often black, white, orange, or blue and labeled as a “filter.” Since the oil filter’s location depends on the model of the vehicle, be sure to check the vehicle’s manual and find the filter more quickly.

How Often to Change Oil Filter?

The average oil filter lifespan is from 3,000 to 5,000 miles. But manufacturers suggest replacing the oil filter every second time you get your oil changed. For instance, if you are on a 6,000-mile cycle, it means you’ll change the filter every 12,000. Still, mechanics may recommend more frequent replacement depending on the following factors:

Service engine light: If you notice your service engine light comes on while driving, it could remind you to change your oil filter. Replace the filter and check if the issue is fixed. If it is not, your car might be experiencing other problems.

Driving in harsh conditions: If your driving includes heavy braking and acceleration or a great deal of stop-and-go traffic in extreme conditions, you will probably need to change both oil and filter more frequently. Harsh driving makes your engine work harder, which results in dirtier oil and a clogged filter.

How Does Oil Filter Work?

The oil filter plays a vital role in removing contaminants from the car engine’s oil, which accumulates over time. Clean motor oil is of the utmost importance because it keeps your engine clean and free from particles that could wear your engine’s surfaces.

How to Loosen Oil Filter?

Your old oil filter may become stuck for various reasons, and it may be pretty challenging to loosen it after some time. In almost all cars, the oil filter is unscrewed counterclockwise, meaning that you must turn the filter in a left way to remove it.

If you cannot unscrew the filter by yourself, rely on a friend or mechanic who has more strength. You can also buy a special oil filter wrench that will help you loosen the oil filter.

How Tight Should an Oil Filter Be?

A suitable oil filter tightness ensures the filter doesn’t fall off or gets damaged while driving. Once you’ve completely screwed the filter in, give it one quarter turn to ensure the filter is placed securely without being too tight.

How to Dispose of Oil Filter?

Since most centers and communities are willing to accept used oil filters, you can recycle yours at any time. You may place your used oil filter in a sealed plastic bag before you leave it for pickup. By recycling used oil filters, you are protecting the environment from hazardous waste.
