Choosing Your 2017 WRX Oil Filter: Beyond the Basics
You've probably seen a wall of oil filters at the auto parts store, each claiming superior performance. For your 2017 WRX, the choice boils down to a few key considerations: OEM vs. Aftermarket, filter media, and capacity. Subaru's OEM filters are engineered to meet the exact specifications of your vehicle, offering a reliable balance of filtration and flow. Many performance-oriented aftermarket brands also offer excellent options, often with enhanced filtration media like synthetic fibers, which can trap smaller particles and last longer.
When considering what's good oil pressure for your WRX, remember that a clean, properly functioning oil filter plays a direct role. If your filter becomes clogged, it can restrict oil flow, potentially leading to lower oil pressure. This is why choosing a filter that maintains optimal flow is vital, especially under spirited driving conditions.
OEM vs. Aftermarket Filters: What's the Real Difference?
Subaru's Genuine Parts oil filters are designed and tested specifically for your WRX. They typically feature cellulose or a blend of cellulose and synthetic fibers, offering a good balance for everyday driving and moderate performance. These filters ensure proper sealing and are built to withstand the pressures and temperatures within the WRX engine. They are often the safest bet for maintaining warranty compliance and predictable performance.
Aftermarket options, however, present a broader spectrum. Brands like K&N, Mobil 1, or Wix often use 100% synthetic media. This synthetic material is denser, meaning it can capture a higher percentage of finer particles and can often handle longer oil change intervals or more extreme conditions. They might also feature a higher burst pressure rating or a silicone anti-drainback valve, which helps maintain oil pressure on startup, especially crucial in colder climates or after the car sits for a while.
A common misconception is that any filter will do. This couldn't be further from the truth, especially for a performance vehicle like the WRX. The wrong filter might have a different thread pitch, seal incorrectly, or have an internal bypass valve that opens too early, allowing unfiltered oil to circulate. Always verify fitment for your 2017 WRX specifically.
Double-check the filter's specifications against your owner's manual or reliable online resources to ensure it meets or exceeds OEM requirements for your 2017 WRX, particularly regarding micron rating and flow rate.
Filter Media and Capacity: What to Look For
The filter media is the heart of the oil filter. Cellulose-based filters are standard and effective for general use. Synthetic media filters, on the other hand, offer superior filtration efficiency (capturing smaller particles) and higher capacity (holding more contaminants before clogging). For a 2017 WRX, especially if you drive it hard or use it in varied conditions, a synthetic or synthetic-blend filter can be a worthwhile upgrade.
Filter capacity refers to how much debris the filter can hold. A filter with higher capacity can last longer before becoming fully saturated. This is linked to the amount and type of filtering media used. When you're looking at filters, consider the operating environment and your typical driving style. If you do a lot of short trips where the engine doesn't reach optimal temperature, or if you regularly push your WRX to its limits, a filter with higher capacity and efficiency is a smart choice.
Performing the Oil Filter Swap and Routine Checks
When it comes time to change your 2017 WRX oil filter, it's an integral part of your oil maintenance routine. The process is generally straightforward, but requires the right tools and a bit of caution. First, ensure your engine is warm, but not scalding hot, as this helps the old oil drain more easily. You'll need a new oil filter, the correct oil, a wrench for the drain plug, a filter wrench, a drain pan, and rags.
Before you even start draining oil, locate your 2017 WRX oil filter. It's typically found near the front of the engine, often accessible from underneath the vehicle. Once you've got your new filter ready, remember to lubricate its rubber gasket with a thin film of new oil. This ensures a proper seal and makes it easier to remove on the next service. Then, screw the new filter on hand-tight until the gasket contacts the mounting surface, and then tighten it an additional 3/4 to one full turn, as per most filter manufacturer instructions. Over-tightening can damage the gasket or the filter housing.
Step-by-Step: Changing Your WRX Oil Filter
Here's a simplified process to guide you:
- Warm up the engine for a few minutes.
- Safely lift and support the front of your WRX using jack stands.
- Locate the oil drain plug on the oil pan and place a drain pan beneath it.
- Remove the drain plug with a wrench and let the old oil drain completely.
- While oil drains, locate the oil filter and place the drain pan underneath it.
- Use a filter wrench to loosen the old filter and unscrew it by hand. Be prepared for oil to spill out.
- Clean the filter mounting surface on the engine block with a rag.
- Lubricate the rubber gasket on the new oil filter with a thin coat of new oil.
- Screw the new filter on by hand until it seats, then tighten an additional 3/4 to one full turn.
- Reinstall the drain plug with a new crush washer and tighten securely.
- Lower the vehicle, fill the engine with the correct type and amount of new oil.
- Start the engine and let it run for a minute, checking for leaks around the filter and drain plug.
- Turn off the engine, wait a few minutes, and check the oil level using the dipstick, adding more if necessary.
This process is fundamental to effective oil maintenance and ensures your engine receives the clean lubricant it needs. You're not just changing a part; you're actively preserving your engine's health.
Beyond the Filter: Vital Oil-Related Checks
While you're under the car performing the oil filter change, take a moment to check your engine oil level. Knowing how do you check your engine oil level is a basic yet critical skill for any car owner. To do this, pull out the dipstick, wipe it clean, reinsert it fully, and pull it out again. The oil level should be between the 'low' and 'full' marks. If it's low, top it up with the appropriate oil type for your 2017 WRX. It's essential to know when should you check engine oil level – ideally, check it weekly or before any long journey.
Also, pay attention to the oil itself. Is it dark and sludgy? Does it smell burnt? These are signs that the oil might be overdue for a change or that the engine is running hotter than it should. While examining the old oil filter after removal, look for any metal shavings or debris. Small amounts of metallic paste can be normal, but large chunks or flakes are a significant warning sign that could indicate internal engine wear. This insight is invaluable if you ever experience issues like why is oil pressure low or why do i have low oil pressure.
When removing the old filter, ensure you have a good grip. If it's stuck, a specialized oil filter wrench that grips from the end or side can provide the leverage you need without damaging the filter housing.
Common Oil Filter Myths and Ensuring Peak Performance
As you become more familiar with your 2017 WRX's needs, you might encounter various opinions or myths surrounding oil filters. One common misconception is that 'more expensive always means better.' While premium filters often use superior materials and construction, the 'best' filter is one that meets or exceeds your specific vehicle's requirements and your driving habits. A high-end filter might be overkill for a commuter, but invaluable for a track-day enthusiast.
Another myth is that oil filters can be reused or that their lifespan is tied solely to mileage rather than time or filter condition. Oil filters are designed for single use and degrade over time as they capture contaminants. Ignoring the recommended service interval for your 2017 WRX oil filter can lead to reduced oil flow and increased engine wear, directly impacting what's normal oil pressure for your engine. A clogged filter can cause oil pressure to drop significantly, potentially leading to catastrophic engine failure.
Debunking Oil Filter Myths for Your WRX
Myth: Any oil filter will work as long as it screws on. Reality: Incorrect thread pitch, bypass valve settings, or seal compatibility can lead to leaks, inadequate filtration, or even engine damage. Always use a filter specified for your 2017 WRX. It's the little things that truly count when it comes to compatibility.
Myth: You can extend oil change intervals indefinitely with a high-quality filter. Reality: While high-capacity and high-efficiency filters can extend intervals slightly, they don't negate the fact that oil breaks down chemically over time due to heat and oxidation. Always follow your manufacturer's recommended oil change schedule, which is crucial for oil maintenance.
Myth: Oil filter color or brand name dictates quality. Reality: Color is purely cosmetic, and while reputable brands generally offer reliable products, even they can have manufacturing defects. Focus on the specifications and materials used in the filter. For performance vehicles like the WRX, understanding the filter's efficiency rating (how well it captures particles) and its capacity is more important than its shiny exterior.
Maintaining Optimal Oil Pressure and Engine Health
Understanding what's normal oil pressure for your 2017 WRX is key to catching potential issues early. This can vary slightly with engine temperature and RPM, but generally, you want to see consistent readings within the manufacturer's specified range. If you notice your oil pressure gauge dropping unexpectedly, or if the oil pressure warning light illuminates, it's a critical situation. First, check your oil level immediately, as low oil is the most common cause. If the oil level is correct, then the issue could be a failing oil pump, a clogged oil pickup screen, or, indeed, a severely clogged or improperly installed oil filter.
If you ever find yourself asking what to do when oil pressure is low, the immediate response should be to shut off the engine as soon as it is safe to do so. Continuing to run an engine with low oil pressure can cause rapid and irreversible damage. After shutting it down, check the oil level. If it's low, add oil and recheck. If the level is fine, the problem is more complex and requires professional diagnosis. This could involve inspecting the oil filter, oil pump, or internal engine components.
Your engine, your story. By paying attention to the details, like your 2017 WRX oil filter, you're writing a positive chapter for your vehicle's performance and longevity. Regular, diligent maintenance ensures that your engine's story is one of power and reliability, not premature failure.
