2016 Subaru Impreza: Choosing The Right Oil Filter

by Alex Braham 51 views

Hey guys! So, you're looking to change the oil filter on your 2016 Subaru Impreza? Awesome! Keeping up with regular oil changes is super important for your car's health and longevity. And choosing the right oil filter is a key part of that process. Let's dive into everything you need to know to make the best choice.

Why the Right Oil Filter Matters for Your Impreza

Okay, so why can't you just slap any old oil filter on your Impreza and call it a day? Well, the oil filter is like the unsung hero of your engine. Its job is to trap all the nasty contaminants – things like dirt, metal shavings, and other debris – that can build up in your engine oil over time. If these contaminants aren't filtered out, they can cause some serious damage, leading to reduced engine performance, increased wear and tear, and even, in the worst-case scenario, engine failure. Not good, right?

A high-quality oil filter ensures that your engine oil stays clean and effective at lubricating all those critical engine parts. This means less friction, better fuel economy, and a longer lifespan for your engine. Think of it this way: you wouldn't drink dirty water, would you? Your engine doesn't want to drink dirty oil either!

Furthermore, using the correct oil filter also maintains the proper oil pressure within your engine. An incompatible or poorly designed filter can restrict oil flow, leading to low oil pressure. Low oil pressure can starve critical engine components of the lubrication they need, leading to premature wear and potential damage. Conversely, a filter that allows too much flow without adequate filtration can let contaminants circulate freely, defeating the purpose of having a filter in the first place.

So, yeah, choosing the right oil filter is kind of a big deal. It's a relatively small and inexpensive part, but it plays a crucial role in keeping your 2016 Impreza running smoothly and reliably for years to come. Now that we know why it matters, let's get into how to choose the right one.

Understanding Oil Filter Specifications for Your 2016 Impreza

Alright, let's get a little technical for a moment, but don't worry, I'll keep it as straightforward as possible. When you're shopping for an oil filter, you'll notice that they come with a bunch of different specifications. Understanding these specs will help you narrow down your choices and ensure you're getting a filter that's compatible with your 2016 Impreza.

  • Size and Thread: This is probably the most crucial specification. You need to make sure the filter is the correct size to physically fit on your engine and that the threads match the threads on your engine's filter mount. Using the wrong size or thread can lead to leaks or even damage to the engine block. Always consult your owner's manual or a reliable parts website to confirm the correct size and thread for your 2016 Impreza.
  • Micron Rating: The micron rating indicates the size of the particles the filter can capture. A lower micron rating means the filter can trap smaller particles, providing better filtration. However, a very low micron rating can also restrict oil flow. Most oil filters for passenger vehicles have a micron rating in the range of 20-30 microns. Choosing a filter with an appropriate micron rating will ensure a good balance between filtration and oil flow.
  • Filter Media: The filter media is the material inside the filter that actually traps the contaminants. Common types of filter media include paper, synthetic fibers, and a blend of both. Synthetic media generally offers better filtration and durability than paper media, but they also tend to be more expensive. Consider your driving habits and budget when choosing a filter media.
  • Bypass Valve: A bypass valve is a safety feature that allows oil to bypass the filter if it becomes clogged or if the oil is too thick (e.g., during cold starts). This prevents the engine from being starved of oil. Make sure the filter you choose has a bypass valve with the correct pressure setting for your 2016 Impreza. Again, your owner's manual or a parts website can provide this information.
  • Anti-Drainback Valve: This valve prevents oil from draining back into the oil pan when the engine is turned off. This helps to ensure that the engine is quickly lubricated when it's started, reducing wear and tear. An anti-drainback valve is especially important for engines with filters that are mounted horizontally or upside down.

Don't be intimidated by all these specifications! Once you understand what they mean, you'll be well-equipped to choose the right oil filter for your Impreza. And remember, when in doubt, consult your owner's manual or a trusted mechanic.

Recommended Oil Filter Brands for the 2016 Subaru Impreza

Okay, so now that you know what to look for in an oil filter, let's talk about some specific brands that are known for making high-quality filters that are compatible with the 2016 Subaru Impreza. These are just a few suggestions, and there are certainly other good brands out there, but these are a great place to start:

  • Subaru OEM Filters: You can't go wrong with the original equipment manufacturer (OEM) filters. These filters are specifically designed for Subaru engines and are guaranteed to meet the manufacturer's specifications. They may be a bit more expensive than aftermarket filters, but you can be confident that they'll provide excellent performance and protection.
  • Wix Filters: Wix is a well-respected brand that's known for making high-quality filters for a wide range of vehicles. Their filters typically feature a durable construction and excellent filtration capabilities. Wix filters are a popular choice among mechanics and DIYers alike.
  • Purolator Filters: Purolator is another reputable brand that offers a variety of oil filters for different applications. Their PurolatorONE filters are a good option for those looking for enhanced filtration and durability.
  • Mobil 1 Filters: Mobil 1 is a well-known brand in the automotive world, and their oil filters are no exception. Mobil 1 filters are designed to provide exceptional filtration and protection, especially when used with synthetic oil.
  • K&N Filters: K&N is best known for their performance air filters, but they also make high-quality oil filters. K&N oil filters are designed for high-performance applications and offer excellent flow rates and filtration.

When choosing a brand, consider your budget, driving habits, and the type of oil you use. If you're using synthetic oil and drive your Impreza hard, you might want to opt for a premium filter like a Mobil 1 or K&N. If you're on a tighter budget and do mostly normal driving, a Wix or Purolator filter will likely be a good choice.
