What is an Oil Filter?


The primary use of an oil filter is to remove waste and capture any debris or dirt mixed into your engine oil. It filters any harmful junk that may cause your engine and engine oil to degrade.

Here are the parts your oil filter has that allow it to work:

1. Tapping Plate

This is the major source of flow for your engine oil. The tapping plate edge has several small holes allowing oil to flow freely. The Tapping plate is attached to the engine through the threaded center hole, which is also where it exits.

2. Anti-drain back Valve

This rubber valve closes when your engine is turned off to ensure the oil does not reach the filter.

3. Filter Medium

The filter medium comprises microscopic cellulose fibers to create a porous filter medium. Synthetic fibers like polyester and glass improve durability and effectiveness. Resin is also added to rigidity and strength.

4. Center Steel Tube

The center steel tube is important in the oil filter’s structure. It provides support and allows the filtered oil to return to the engine.

5. Relief Valve

The relief valve prevents a cold engine from starving by letting unfiltered oil into the center tube.

What are Mobil 1 Oil Filters?


High-performance lubricants are a trademark of the Mobil 1 brand, and their oil filters are no exception. Mobil 1 Extended Performance Oil filters use synthetic mix media giving your car better performance and longer engine life.

Mobile 1 offers a 1-year warranty for their oil filters which is ideal for long-lasting protection. When combined with their Advanced Full Synthetic Motor Oil, Mobil 1 Oil Filters can increase their performance.

What Are FRAM Oil Filters?


FRAM is one of the top brands of oil filters in the USA. It continues to produce and sell a wide range of high-quality oil, air, fuel filters, and other vehicle accessories.

Difference Between Oil Filters


1. Filtration Efficiency

One of the main differences between Fram and Mobil 1 oil filters is their filtration efficiency. Filter efficiency measures a filter’s capacity to capture and hold particles of a particular size.

Particulate sizes are measured in Microns which is precisely a millionth of a meter.


  • FRAM oil filters are 99%+ efficient for particles greater than 20 microns.
  • While Mobil 1 oil filters have a 99% efficiency rating for particles greater than 30 microns.

While Mobil 1 filters do a good job of filtering out dirt and contaminants, FRAM oil filters are designed to capture even the smallest particles, ensuring that your engine remains clean and efficient.

2. Build

Another difference between Fram and Mobil 1 oil filters is their construction.


  • FRAM oil filter walls include O-rings and gaskets that are designed to withstand pressures of up to three times what a typical car engine can generate.
  • Mobil 1 oil filters, however, have an amazing build that can withstand up to 615 psi or nine times the typical engine operating pressure.

3. Longevity


An important factor to consider when choosing your oil filter is how long they last. Various oil filters are available from Mobil 1 and Fram, all of which are intended to last for different lengths of time.

Mobil 1 oil filters are known for their durability and long-lasting performance when combined with their Extended Performance Engine Oil. These filters typically last for 20,000 miles or one year, whichever comes first, and are guaranteed with a warranty.

FRAM also has a decent amount of longevity. One of their more expensive options, the FRAM titanium oil filter can last for up to 20,000 miles while Extra Guard, the cheapest option lasts for 3,000 to 5,000 miles which is about the same as a Mobil 1 oil filter with any other oil.

4. Price

Fram oil filters are generally more affordable than Mobil 1 oil filters. This is because Fram is a more budget-friendly brand, while Mobil 1 is a premium brand that offers advanced features and technology.

The Mobil 1 Extended Performance Oil Filter can go up to $11 while most FRAM filters go about $6-$8 on Amazon.

Tips to Find the Right Oil Filter for You

Finding the right engine oil filter for your car is an essential part of routine maintenance. Here are some tips to help you find the right oil filter for your needs:

1. Look up your owner’s manual

Your car’s manual will have detailed information on the type of oil filter recommended for your specific make and model. Be sure to follow the manufacturer’s recommendations to ensure you get the right oil filter for your vehicle.

2. Match the filter to your Driving Style


Consider your driving habits when selecting an oil filter. If you drive in dusty or dirty conditions, you may need a filter with a higher filtration rating.

If you drive in extreme temperatures, you may need a filter designed to perform well in those conditions. Installing a wrong filter may break its bypass valve, allowing unfiltered oil to enter your engine.

3. Use Synthetic Oil


Synthetic oils are made from refined petroleum. Unlike mineral oil which is derived from crude petroleum, fully synthetic oils provide better performance for your vehicle.

By incorporating additives into synthetic oils, they become much more viscous, better at resisting heat and cleaning your engine, and provide much better lubrication.

Pros and Cons

Now that we have a good idea about Fram and Mobil 1 oil filters let’s check out this breakdown of the pros and cons of each product.


  • 99+% Efficient at 20 microns
  • Can last up to 20,000 miles

Can I use any type of oil filter on my car?

What happens if I don’t change my oil filter?

Both the FRAM and Mobil 1 have their strengths and weaknesses. FRAM prides itself on being the cheaper option with a weaker build but with slightly better filtration.
