Walmart Motor Oil Filter: Your Complete Guide to Choosing and Using the Right Filter
When it comes to maintaining your vehicle's engine health, choosing the right oil filter is just as important as selecting quality motor oil. Walmart offers a comprehensive range of oil filters that cater to various vehicle types, driving conditions, and budget requirements. Whether you're performing a DIY oil change or seeking professional service, understanding the options available at Walmart can help you make informed decisions that protect your engine and save money over time.
Why Oil Filters Matter for Your Engine
Oil filters play a critical role in maintaining engine performance and longevity. As oil circulates through your engine, it picks up contaminants like metal particles, dirt, and other debris that can cause significant wear on moving parts. The oil filter's job is to trap these impurities, ensuring only clean oil reaches vital engine components. Without proper filtration, contaminants can accumulate and lead to reduced engine efficiency, increased fuel consumption, and potentially costly repairs down the road.
Walmart's oil filter selection includes options from trusted brands like FRAM, Purolator, and their own Supertech line, each designed to meet different performance needs and price points. The key is selecting a filter that matches your vehicle's specifications and your driving habits.
Types of Oil Filters Available at Walmart
FRAM Extra Guard Oil Filters
FRAM Extra Guard oil filters are engineered for everyday drivers who perform regular oil changes. These filters feature a special blend of fibers and resin that creates proprietary filter media capable of capturing 95% of dirt particles that can cause harmful engine wear. The silicone anti-drainback valve provides up to three times the hot oil resistance compared to standard valves, ensuring your engine receives immediate protection upon startup. The SureGrip no-slip finish makes installation and removal easier, while the internally lubricated sealing gasket helps prevent sticking during future oil changes.
Purolator 20K Premium Oil Filter
For drivers seeking extended protection, the Purolator 20K Premium Oil Filter offers up to 20,000 miles of engine protection. This filter is designed with high-density synthetic blend media that captures more than 99% of dirt and contaminants, making it ideal for vehicles that experience frequent towing, off-roading, or stop-and-go traffic. The silicone anti-drainback valve prevents dry starts, while the PuroSEAL gasket provides superior leak protection. The PuroSTEEL casing withstands extreme pressure conditions, making this filter a top choice for high-performance applications.
Supertech Oil Filters
Walmart's in-house Supertech brand offers budget-friendly oil filters that provide basic filtration needs for everyday driving conditions. These filters can handle both conventional and synthetic oils, with some models specifically designed for synthetic oil applications. While Supertech filters may not offer the same level of filtration efficiency as premium brands, they serve as a cost-effective option for routine maintenance when changed regularly.
How to Choose the Right Oil Filter
Selecting the correct oil filter for your vehicle involves several key considerations:
Vehicle Compatibility
Always check your vehicle's owner's manual for the manufacturer's recommended oil filter specifications. Using the wrong filter size or type can lead to improper fitment, leaks, or inadequate filtration. Walmart's website features an oil selector tool that helps you find the right filter based on your vehicle's year, make, model, and engine type.
Driving Conditions
Consider your typical driving habits when choosing an oil filter. If you frequently tow heavy loads, drive in extreme temperatures, or engage in off-road activities, a premium filter like the Purolator 20K may be worth the investment. For standard commuting and highway driving, a mid-range filter like FRAM Extra Guard provides adequate protection at a reasonable price.
Oil Change Intervals
If you follow extended oil change intervals (10,000 miles or more), opt for a filter designed for long-term protection. Premium filters with synthetic media and advanced construction materials can maintain filtration efficiency over longer periods. For traditional 3,000-5,000 mile oil change intervals, standard filters may be sufficient.
Budget Considerations
While it's tempting to choose the cheapest option, remember that oil filters represent a relatively small portion of your overall maintenance costs. Investing a few extra dollars in a quality filter can provide better engine protection and potentially prevent expensive repairs later.
Step-by-Step Oil Filter Installation Guide
Changing your oil filter is a straightforward process that most DIY enthusiasts can handle with basic tools. Here's how to do it properly:
Tools and Materials Needed
- New oil filter (specific to your vehicle)
- Oil filter wrench
- Drain pan (at least 5-7 quart capacity)
- Socket set
- Funnel
- Clean rags or paper towels
- Disposable gloves
- Safety glasses
Safety Precautions
Always work on a flat surface with the engine off and the parking brake engaged. Allow the engine to cool if you've been driving recently. Use jack stands if you need to access the filter from underneath the vehicle, and never rely solely on a jack for support.
Installation Steps
-
Locate the Oil Filter
The oil filter is typically located on the side or bottom of the engine block. Position your drain pan underneath it to catch any oil that may spill during removal. -
Remove the Old Filter
Using an oil filter wrench, turn the filter counterclockwise to loosen it. Once loose, you can typically finish unscrewing it by hand. Be careful as the filter may contain oil and feel heavy. -
Prepare the New Filter
Before installing the new filter, apply a thin film of clean oil to the rubber gasket on the top of the filter. This helps create a proper seal and makes future removal easier. Do not use grease on the gasket. -
Install the New Filter
Screw the new filter onto the engine by hand until the gasket makes contact with the mounting surface. Then tighten it an additional 1/2 to 3/4 turn using the filter wrench. Avoid over-tightening, as this can damage the filter or make it difficult to remove next time. -
Refill Engine Oil
Replace the oil drain plug and tighten it securely. Add the recommended amount and type of oil through the oil fill cap using a funnel. Check your owner's manual for the correct oil specification and capacity. -
Check for Leaks
Start the engine and let it run for a few minutes. Check around the oil filter and drain plug for any signs of leakage. If you notice leaks, shut off the engine immediately and tighten the filter or drain plug as needed. -
Final Oil Level Check
Turn off the engine and wait a few minutes for oil to settle. Check the oil level with the dipstick and add more oil if necessary to reach the "full" mark.
Maintenance Tips for Optimal Performance
Regular Inspection
Check your oil level at least once a month and before long trips. Look for signs of oil contamination or discoloration, which could indicate the filter needs replacement sooner than scheduled.
Follow Manufacturer Recommendations
Adhere to your vehicle manufacturer's recommended oil change intervals. While some filters claim extended protection, it's generally better to follow the more conservative recommendations in your owner's manual.
Use Quality Oil
Pair your oil filter with high-quality motor oil that meets or exceeds your vehicle's specifications. The combination of good oil and a quality filter provides the best protection for your engine.
Monitor Driving Conditions
If you frequently drive in dusty conditions, tow heavy loads, or make frequent short trips where the engine doesn't fully warm up, consider changing your oil and filter more frequently than the standard interval.
Common Mistakes to Avoid
Using the Wrong Filter
Always double-check that the filter you're installing matches your vehicle's specifications. Using an incorrect filter can lead to poor filtration, leaks, or even engine damage.
Over-Tightening
Tightening the oil filter too much can damage the gasket or make it extremely difficult to remove during the next oil change. Hand-tight plus 1/2 to 3/4 turn is typically sufficient.
Forgetting to Lubricate the Gasket
Skipping the step of applying oil to the new filter's gasket can cause the gasket to stick or tear during installation, leading to leaks.
Reusing Old Oil
Never reuse old oil that has been drained from your engine. Used oil contains contaminants that can harm your engine even with a new filter.
Cost Comparison: DIY vs. Professional Service
Performing your own oil change with Walmart products can provide significant savings compared to professional service. Here's a typical cost breakdown:
DIY Oil Change
- 5 quarts of full synthetic motor oil:
23-27 - Oil filter:
10-15 - Total:
33-42
Walmart Auto Center Service
- Full synthetic oil change: $54.88
The DIY approach saves approximately 10-25 per oil change. However, consider that Walmart's service includes labor, topping up other fluids, and a quick vehicle inspection. If you value convenience or lack the tools and space to perform the work yourself, the professional service may be worth the additional cost.
Environmental Considerations
Proper disposal of used oil and filters is essential for environmental protection. Never pour used oil down drains, on the ground, or in the trash. Walmart Auto Centers and many auto parts stores accept used oil and filters for recycling at no charge. Used oil can be re-refined and reused, while filters can be recycled for their metal content.
When to Seek Professional Help
While changing your oil filter is a relatively simple task, there are situations where professional assistance is recommended:
- If you're uncomfortable working under your vehicle
- When you don't have the proper tools or workspace
- If you notice significant oil leaks or engine problems
- For vehicles with difficult-to-access filter locations
- When you're short on time and prefer convenience
Walmart Auto Centers offer professional oil change services performed by trained technicians who can handle the job quickly and efficiently.
Final Recommendations
Choosing the right oil filter from Walmart depends on your specific needs and budget. For most everyday drivers, the FRAM Extra Guard filter provides excellent protection at a reasonable price point. If you drive under demanding conditions or prefer extended oil change intervals, the Purolator 20K Premium filter offers superior filtration and durability. Budget-conscious consumers can consider Supertech filters for routine maintenance when changed regularly.
Remember that regular oil and filter changes are among the most important maintenance tasks you can perform for your vehicle. By selecting quality products from Walmart and following proper installation procedures, you can ensure your engine receives the protection it needs for years of reliable service.
