What do numbers on oil filter mean?

Nominal Micron Rating expresses the ability of the filter to capture particles of a specified size in microns at an efficiency of 50%. A nominal rating of 50% at 10 microns simply means that a filter captures 50% of contaminants 10 microns in size.

How do you read oil filter numbers?

Understanding Oil Filter Ratings

  1. BX=2. The “X” denotes the size in microns of particles above which the filter is only removing 50 percent of the particles entering. …
  2. B10=X. The “X” in this case denotes the Beta ratio corresponding to particles larger than 10 microns. …
  3. BX=75.

Does it matter which oil filter I use?

Every major motor oil manufacturer says you do not need a special or different oil filter when using synthetic oil. The better quality an oil filter is, the better job it will do in filtering contaminants.

How do oil filter sizes work?

Because the larger filter will have a greater filtering surface than the smaller one. The larger filter may also have a lower pressure drop as oil is passed through it. However, the most important spec is the pressure at which the bypass valve will open.

Is a 20 micron oil filter good?

The key is to look for a filter that tests at the industry standard using particles at 20 microns using the ISO 4548-12 test. Particles in the 10-20 micron range cause the most damage and wear to an engine.

What is oil filter micron rating?

The micron rating is the size at which particles are retained by the filter. For example, a five-micron filter will stop particles of five microns or larger from passing through the media.

Is it OK to use a synthetic oil filter with regular oil?

Yes, it’s perfectly safe to use either type of filter with either type of oil. If you practice extended drain intervals using synthetic oil, however, a conventional oil filter may not offer the required service life, meaning you’ll have to change it in the middle of the oil drain interval, which is inconvenient.

Is K&N a good oil filter?

The Performance Gold ultra-premium line is a top choice among racers and high-performance vehicle owners. Available in both canister and cartridge styles, HP filters are the highest quality oil filters that K&N offers, designed for exceptional filtration and long-lasting, durable protection.

Why does my car have 2 oil filters?

It is actually HCM (Hydraulic Control Module) filter. The HCM sucks oil directly out of the oil tank and the oil needs to be filtered before going to all the components of that system. This is the same for the engine. Two separate systems sharing the same oil.

Is bigger oil filter better?

A larger oil filter might give you the “warm and fuzzies”, but more than likely, the extra capacity is completely redundant anyway. Consider if the extra oil filter capacity is worth the risk of operating without warranty coverage (should the unthinkable happen).

Why are some oil filters bigger?

Larger or higher-powered engines, such as those in heavy-duty hauling vehicles or performance cars, will require more oil flowing at a higher rate to keep things cool and lubricated, which means they’ll need a bigger filter. Different filters can also perform different duties on different vehicle .

How many microns is a WIX oil filter?

Wix is second to none in filters we all know that. They way this long interval oil change filter works (that’s what it is) is the micron rating is higher (35 micron).

Is a 30 micron oil filter good?

“A micron rating is given to show the efficiency of the oil filter (one micron is a millionth of a meter). … The 30 micron filter is designed to work best for your Evolution style engine, the filtration is still excellent and it will not cause oiling issues. When it comes to filtering oil, application is very important.

What is the difference between 1 micron and 5 micron filter?

A 5 micron water filter will sieve out particles that you can see – but all the other smaller particles will pass through it into your drinking water. By contrast a 1 micron filter will remove particles not visible to the naked eye.
