What To Consider Before Buying An Oil Filter?

We’re helping you to find the best oil filter for the Duramax diesel engines. But, you need to know what aspects to look for and evaluate to acquire the best oil filter for 6.6 Duramax diesel engines. Before making a purchase, consider the following criteria:

A. Oil Filtration

An oil filter must filter all potential contaminants to qualify as high-quality. All filters would have a micron rating, which would assess the particle size that the filter medium can effectively catch.

For peak performance, use an oil filter with a micron level of 5 or higher. An appropriate oil filter also features a metal end cap and a middle tube.

B. Properties For High Temperature

Almost all filter media are suitable for use with water-based products. When filtering hot oil, glue, or any high-temperature substance, use a filter medium to withstand high temperatures and extended exposure.

The best oil filter for Duramax LML should withstand high temperatures for efficient filtration.

Filtration media is a filter used to remove contaminants from engine oil. The most regularly used filtering medium is listed below:

  • Mechanical: It consists of pleated filter paper, which collects impurities on the surface and separates oil from pollutants.
  • Magnetic: This type of oil filter uses electromagnets as the filter media.
  • Sedimentation: There is no unique filtering material in this. These rely on gravity to perform all of the filter’s functions.
  • Centrifugal: This design compels the oil to spin at a set pace inside the enclosure.

C. Durability

Top-tier oil filters can withstand continuous contact with trash, air particles, dirt, and even tiny pebbles or gravel. When exposed to these factors, a lower-quality product may degrade.

You need to ensure that the oil filter can handle harsh climates and terrains. Filter materials include the following:

  • Cellulose: These filters are disposable filters that may stop particles as small as 8-10 microns.
  • Synthetic: These filters use glass, nylon, and polyester. It can remove even the tiniest particles from the fluid. And it can last up to 6000 miles before changing.
  • Micro-Glass: Most of the best filter manufacturers use micro-glass in the making. These filters are almost ten times better than cellulose filters. This can eliminate even the tiniest particles and can last up to 10,000 miles before needing to be replaced.

What Are The Different Types Of Oil Filters For Duramax LML?

An oil filter is a mechanical device that keeps contaminants, dirt, and unburned gasoline out of the fuel supply. The component only enables new oil to circulate into the engine while keeping dirt out. You should treat or replace the oil filter after a particular period.

Other car hydraulic systems use an oil filter, such as automatic gearboxes and power steering. Oil filters are also usable in gas turbine engines like jets. The filter is used in vehicles, boats, and airplanes to purify the oil and remove dirt.

Therefore, there are 5 different oil filters, which help keep the mechanism dirt-free. So, we’re here to discuss these types of oil filters. Keep reading.

A. Primary Oil Filters

These are the most common motor oil filter types. They’re also known as full-flow filters, and they filter out all contaminants thoroughly. Oil filters limit the flow of oil since they must filter it continually.

Restricting the flow of oil can damage the engine. Primary oil filters help to avoid this by reducing the amount of impediment to oil flow.

The engine oil sets in cold temperatures, causing it to travel more slowly through the system. Primary oil filters do not create this problem since they do not impede the oil from flowing freely through the engine.

This type of filter enables comparatively bigger particles to pass through. Automobile manufacturers provide a bypass valve if the membrane becomes too clogged with pollutants as a safety measure.

B. Secondary Oil Filters

Besides the basic oil filters, these are essential to your car’s system. On the other hand, secondary filters operate independently of their primary counterparts.

These filters purify a tiny amount of engine oil by filtering it and removing excess impurities. Since additional filters work alongside the other filters, it doesn’t require frequent oil replacement.

If your car does not come with secondary oil filters, you may always add them afterward. Secondary oil filters, often known as bypass filters, are not the same as bypass valves.

C. Thermal Chamber Oil Filters

These filters serve two purposes. They do not only filter oil like traditional oil filters, but they also offer an additional feature.

These filters raise the oil’s temperature to allow some impurities to burn or disintegrate. These filters require energy for this reason.

The filters deplete your car’s power source, lowering its fuel efficiency. This is a disadvantage of using this type of filter.

D. Centrifugal Filters

Centrifugal oil filters are another name for them. The contaminants in the oil are pushed to the bottom of the filters as they spin at high speeds. A membrane and a housing chamber make up the filters. You need to replace the membrane if it becomes blocked with pollutants.

However, you can still use the housing chamber if it is in fine condition. A base gasket at the bottom of the filters prevents oil from pouring through. After 3000 miles of driving, you should examine the base gasket.

E. Magnetic Oil Filters

As their name indicates, these magnetic filters attract and eliminate tiny metal impurities contained in the oil. These filters cannot remove dust because they cannot collect dust.

There is no need to replace these filters; simply cleaning them often and properly should ensure that they provide optimal performance.

FAQs About Best Oil Filter For Duramax LML

What Does The Oil Filter Do?

Motor oil is required to lubricate your vehicle’s engine and moving parts. The engine also needs to seal out impurities that might hinder performance when utilizing the oil.

The filter removes any debris, metal fragments, or dirt that may have gotten into the oil. We strongly recommend installing the filters on your Duramax truck to improve drivability.

When Should I Change My Oil Filter?

According to most experts, you should change the oil and oil filter every 7,500 to 10,000 miles. These are the three signs that it’s time to replace it:

  • Change your oil filter every time you change your car’s oil
  • When the service engine light is off
  • When being driven in extreme terrains and conditions
Does Synthetic Engine Oil Require A Special Filter?

Major motor oil producers say that synthetic oil does not require a unique or specialized oil filter. Oil filters of high quality will filter pollutants more effectively since they are of higher quality.

It is entirely OK to use any type of filter with oil. On the other hand, synthetic oil may not give the requisite service life. You must change the conventional oil filter during the oil drain period. However, it is difficult to use synthetic oil with prolonged drain intervals.

Do Oil Filters Matter?

Oil filters extend the life of your oil and allow you to travel further between oil changes.

The oil may circumvent the filter in rare situations. Such as when the filter is blocked or when oil thickens and cannot move through it correctly during icy conditions.

Does The Oil Filter Brand Matter?

The manufacturer is generally the one who makes a decent, excellent, or best filter. You won’t have to pay extra for a better filter if you use mineral oil and change your filter regularly.

You should choose a top-of-the-line filter brand if you use synthetic oils or plan to change them more regularly.

Can I Use The Same Filter Twice?

The filter captures pollutants and keeps them within the medium of the filter. Dirt particles, agglomerated soot, metal particles, and other debris accumulate in the medium over time.

The pressure differential will activate the bypass valve if the filter blocks. It allows oil to bypass and prevent oil starvation. Sure, dirty oil is better than no oil, but it’s not a long-term solution.

Final Thoughts

The oil filter is crucial for a healthy and smooth-running vehicle. Anyone familiar with automobiles is fully aware of this.
