2020 Nissan Armada Oil Filter

Alright, let's dive into the oil filter situation for your 2020 Nissan Armada. Choosing the right oil filter is crucial for maintaining the health of your VK56VD engine and extending its lifespan. While it might seem like a simple component, there's a surprising amount of engineering packed into that small canister. We'll cover OEM options, aftermarket alternatives, key specs to consider, and the installation process.

OEM Oil Filter: A Known Quantity

The OEM (Original Equipment Manufacturer) oil filter for your 2020 Armada is typically a Nissan part number 15208-9E01A or its updated successor. This filter is designed specifically for the VK56VD engine and meets Nissan's stringent quality control standards. Using the OEM filter gives you a baseline of performance and ensures compatibility with your vehicle's oil system.

Benefits of sticking with OEM filters:

Guaranteed Fitment: No guesswork involved. It's designed to fit perfectly.
Correct Pressure Relief Valve Setting: The OEM filter contains a pressure relief valve designed to open at a specific PSI (pounds per square inch). This valve bypasses the filter media if it becomes clogged or if the oil is too viscous (thick) – especially during cold starts. This prevents oil starvation and engine damage. Using an incorrect pressure relief valve can lead to either insufficient lubrication or excessive wear.
Validated Filtration Efficiency: Nissan has tested this filter with their specific oil formulations and engine parameters, ensuring it meets their standards for particle removal.

However, OEM isn't always the only – or even the best – option. Let's explore some aftermarket alternatives.

Aftermarket Oil Filter Options: Performance and Value

The aftermarket offers a plethora of oil filters claiming to be superior to the OEM. Brands like Mobil 1, K&N, Bosch, Purolator, and Wix are popular choices. When selecting an aftermarket filter, it's vital to do your research and choose a reputable brand known for quality and consistent performance.

Here's what to look for in a good aftermarket oil filter:

Filtration Media

The filter media is the heart of any oil filter. It's what actually traps the contaminants. Different types of media exist:

Cellulose: A common and inexpensive option, cellulose media is typically made from paper fibers. It offers decent filtration but can become less effective when saturated with oil or subjected to high temperatures.
Synthetic: Synthetic media, often made from microglass or a blend of synthetic fibers, offers superior filtration efficiency and can trap smaller particles compared to cellulose. They also tend to be more resistant to heat and degradation. Brands like Mobil 1 and K&N often use synthetic or synthetic-blend media in their premium filters.
Cellulose/Synthetic Blend: A compromise between cost and performance, these filters combine cellulose and synthetic fibers to improve filtration efficiency and durability compared to pure cellulose filters.

Micron rating is a crucial factor. This indicates the size of the particles the filter can effectively remove. A lower micron rating generally means finer filtration. However, extremely fine filtration can also restrict oil flow, especially with heavier weight oils or in colder climates. Pay attention to the filter's beta ratio as well. This ratio indicates the percentage of particles of a certain size that the filter can capture. A higher beta ratio indicates better filtration efficiency. For instance, a beta ratio of 20 for 20 microns means that for every 20 particles of 20 microns or larger that enter the filter, only 1 will pass through.

Construction and Durability

The physical construction of the filter is just as important as the media. Look for these features:

Heavy-Duty Canister: A thicker canister can withstand higher pressures and is less likely to rupture under extreme conditions.
Proper Sealing: The filter needs a reliable gasket to create a tight seal against the engine block. A poorly designed gasket can leak, leading to oil loss and potential engine damage. Examine the gasket material for cracks or damage before installation.
Strong Internal Components: The internal components, such as the center tube and end caps, should be robust and able to withstand the pressure and heat within the oil system.
Anti-Drainback Valve: This valve prevents oil from draining back into the oil pan when the engine is off. This ensures that oil is readily available at startup, reducing wear and tear on engine components. Ensure the anti-drainback valve is made of a durable material that won't crack or deform over time. Silicone is a good choice.

Pressure Relief Valve (Bypass Valve)

As mentioned earlier, the pressure relief valve is a critical safety feature. Make sure the aftermarket filter has a pressure relief valve set to the correct pressure specification for your 2020 Armada's VK56VD engine. This information is usually available in the manufacturer's specifications. Using a filter with the wrong pressure relief valve setting can have detrimental effects on your engine's lubrication system.

Important Note: Don't fall for marketing hype alone. Look for independent testing data or reviews from reputable sources that evaluate the filter's actual performance, not just its advertised claims.

Key Specs to Consider for Your 2020 Armada

Before you buy any oil filter, OEM or aftermarket, make sure it meets the following requirements:

Thread Size: This is crucial for proper fitment. Incorrect thread size will prevent you from screwing the filter onto the engine block.
Gasket Diameter: The gasket must properly seal against the engine block to prevent oil leaks.
Filter Height and Diameter: Ensure the filter fits within the available space in your engine compartment and doesn't interfere with any other components.
Flow Rate: This refers to the amount of oil the filter can process per unit of time. A filter with a lower-than-required flow rate can restrict oil flow, especially at higher engine speeds. Consult your vehicle's service manual or the oil filter manufacturer's specifications for the recommended flow rate.

Oil Filter Installation: A Step-by-Step Guide

Replacing the oil filter on your 2020 Armada is a straightforward process, but safety should always be your top priority. Here's how to do it:

Gather Your Supplies: You'll need a new oil filter, the correct type and amount of engine oil (check your owner's manual), an oil filter wrench, a wrench for the drain plug, a drain pan, gloves, and rags or paper towels.
Warm Up the Engine: Run the engine for a few minutes to warm the oil. Warm oil flows more easily, which helps to remove contaminants. However, be careful not to overheat the oil, as it can scald you.
Safely Lift the Vehicle: Use a jack and jack stands to safely lift the vehicle. Never work under a vehicle supported only by a jack.
Locate the Oil Drain Plug: It's typically on the bottom of the oil pan. Position the drain pan underneath the drain plug.
Remove the Drain Plug: Use the appropriate wrench to loosen and remove the drain plug. Let the oil drain completely.
Locate the Oil Filter: On the 2020 Armada, the oil filter location is usually easily accessible from underneath the vehicle.
Loosen the Old Oil Filter: Use the oil filter wrench to loosen the old filter. You may need to apply some force.
Remove the Old Oil Filter: Unscrew the old filter by hand. Be prepared for some oil to spill out. Have rags or paper towels ready to catch the drips.
Prepare the New Oil Filter: Lightly lubricate the rubber gasket on the new oil filter with fresh engine oil. This helps to create a better seal.
Install the New Oil Filter: Screw the new filter onto the engine block by hand until the gasket makes contact with the sealing surface. Then, tighten the filter an additional ¾ to 1 full turn, or as specified by the filter manufacturer. Do not overtighten.
Reinstall the Drain Plug: Clean the drain plug and install a new crush washer (if applicable). Tighten the drain plug to the specified torque. Overtightening can damage the oil pan.
Lower the Vehicle: Carefully lower the vehicle back to the ground.
Add New Oil: Remove the oil fill cap on top of the engine and add the correct amount of new oil, according to your owner's manual.
Check the Oil Level: Use the dipstick to check the oil level. Add more oil if necessary to reach the "full" mark.
Start the Engine: Start the engine and let it run for a few minutes. Check for any oil leaks around the drain plug and oil filter.
Recheck the Oil Level: After running the engine, turn it off and let it sit for a few minutes. Recheck the oil level and add more oil if needed.
Properly Dispose of Used Oil and Filter: Take the used oil and filter to a recycling center or auto parts store for proper disposal. Do not dump them down the drain or in the trash.

Safety First: Always wear gloves when handling used oil, as it can contain harmful contaminants. Dispose of used oil and filters properly to protect the environment.
