Wow, you really have been saving up oil filter questions for 50 years, Randy. I'm glad you didn't wait another 10 years or I'd have to take over the Real Estate section to finish this answer.
The reason there are so many different filters is because engines are all different. And space is at a premium. Most engine compartments I work on these days have no room to spare. So when designing an engine, all the immovable parts are designed first. Then later in the process, they find a place for the filter, preferably right on the engine block. In order to fit oil filters into the nooks and crannies manufacturers ultimately allot for them, filters have to come in all different shapes and sizes.
Generally speaking, more expensive filters are better than cheap ones, because they use better filtration materials. Instead of plain old Charmin, filters now use materials like synthetic glass microfibers, which do a better job of filtering the oil. That's also why smaller filters can be used. With better filtration materials, they can provide all the filtration the engine needs in a smaller volume.
We tend to stick with OEM filters -- the filters made by the car's manufacturer. You can never go wrong with those. Modern filters also have check valves, which explains why the oil doesn't drain out of your Subaru filter, even though it's mounted upside-down. Without a check valve, the oil would drain out, and that would be a problem. If the oil drained out, every time you started your car, your oil pump first would have to fill the oil filter, leaving other parts under lubricated for those first few crucial seconds that the engine is running. But the check valve keeps the filter full and completely solves that problem.
So, basically, Randy, there's nothing to worry about. Stick with a Subaru filter or other quality brand, and you'll get all the filtration you need. I'll look forward to hearing from you in 50 years.
When it comes to maintaining your vehicle’s engine health, using the right oil filter is paramount. An oil filter plays a crucial role in trapping contaminants and preventing them from circulating through the engine, ensuring optimal performance and longevity. In this blog post, we will guide you through the process of choosing the right oil filter by considering factors such as brand reputation, filtration efficiency, compatibility, and maintenance requirements.
The oil filter plays a critical role in automotive maintenance by helping to keep the engine’s lubricating oil clean and free from contaminants. Not all oil filters are created equal, which is why it’s important that you understand the difference between the cheapest filter out there, and the more premium options. Before we get to that, here’s why a good oil filter is such an important part of automotive maintenance.
As the engine operates, tiny metal particles, dirt, dust, and other debris can find their way into the oil. The oil filter’s primary function is to trap and remove these contaminants from the oil, preventing them from circulating through the engine. If these particles are allowed to circulate, they can cause excessive engine wear, leading to reduced performance, increased fuel consumption, and potential engine damage over time.
The oil filter helps to protect vital engine components, such as the crankshaft, camshaft, bearings, and pistons, from damage. By removing contaminants from the oil, it prevents abrasive particles from coming into contact with these sensitive parts, reducing friction and wear. This, in turn, promotes the longevity and optimal performance of the engine.
Over time, oil accumulates impurities and breaks down due to heat, oxidation, and chemical reactions. A clogged or inefficient oil filter can allow these contaminants to build up in the oil, reducing its lubricating properties and compromising its ability to protect the engine. By regularly replacing the oil filter, you ensure that the oil remains clean and capable of providing proper lubrication, which is crucial for the smooth operation and longevity of the engine.
Clean oil is vital for maintaining optimal engine performance. When the oil is free from contaminants and debris, it can flow smoothly through the engine, reducing friction and heat. This helps to maximize fuel efficiency, improve power output, and minimize wear and tear on engine components. An efficient oil filter contributes to the overall health and performance of the engine.
Alright, now that we know what the oil filter does and how important it is, let’s discuss choosing the right filter for your car. There are a few things to consider here.
Not all oil filters are compatible with every vehicle. The design of the engine dictates the position and shape of the filter, which is why different cars tend to use different filters. Ensure that the oil filter you choose is specifically designed for your vehicle’s make, model, and engine size. Consulting your vehicle’s owner’s manual or contacting the manufacturer can provide you with the exact specifications and part numbers needed for a compatible oil filter.
Choosing a reputable brand for your oil filter is essential to ensure reliability and performance. Established brands often have a proven track record of producing high-quality filters that meet or exceed industry standards. Researching customer reviews and consulting with automotive experts can help you identify reliable brands that are trusted within the industry. We’ve added a few recommendations of our own further down in this guide.
The primary purpose of an oil filter is to capture contaminants, such as dirt, debris, and metal particles, to prevent them from circulating through the engine. Look for oil filters that offer high filtration efficiency, measured by their ability to trap smaller particles. Filters with better filtration efficiency will help maintain cleaner oil and protect your engine from potential damage.
Some oil filters require more frequent replacements than others. Consider the filter’s recommended service interval and the manufacturer’s guidelines. Additionally, factors such as your driving habits and operating conditions may influence the frequency at which you should change the oil filter. Regularly replacing the oil filter at the recommended intervals is vital to maintaining engine health.
While it’s tempting to choose the cheapest oil filter available, it’s essential to strike a balance between cost and value. Investing in a quality oil filter may cost slightly more upfront but can save you money in the long run by providing better filtration and protecting your engine from potential damage.
As mentioned before, there are many oil filter brands out there. However, not all of them are the same. When you’re looking to keep your engine healthy long-term, it’s important to understand these differences in filtration technologies, filter designs, and other factors that come into play with oil filters. With that said, here are some of the brands you can trust to keep the nasty stuff out of your oil.
