Removal of impurities
The elementary function of an oil filter is to remove impurities and contaminants from engine oil. Over time, dirt, metal particles, dust and sludge can build up in the oil, increasing friction and wear on your engine. Oil filters trap these particles, preventing them from circulating and potentially causing damage. By keeping the oil clean and free of dirt, the filter provides proper lubrication. This is essential to reduce friction, heat and general engine wear.

Improved engine performance
A clean, well-lubricated engine runs more efficiently, resulting in better performance. Oil filters help keep your engine in optimum condition by keeping dirt and debris from reaching critical engine components. A clean engine will run smoother and reduce the risk of friction-related problems such as overheating and loss of power. Therefore, a properly functioning oil filter will result in better fuel economy and a smoother driving experience.

Extended engine life
Regularly transforming the oil and oil filters can significantly extend the life of your engine. Over time, the build-up of contaminants can cause engine parts to corrode and wear, resulting in poor performance and costly repairs. Extra costs get incurred in the form of overburdening repairs and damage. An oil filter minimizes these risks by keeping the oil clean, extending the life of your engine. Regularly changing your oil filters will continue to protect your engine from harmful particles, maintain its performance, and potentially save you costly engine repairs or replacements.

Cost-effective and minimum maintenance
Investing in a quality oil filter is a cost-effective way to maintain your vehicle. Oil filters are relatively inexpensive compared to engine repairs, so it's a wise choice. By filtering out contaminants and maintaining proper lubrication, oil filters reduce stress on engine components and prevent premature wear. This helps you avoid expensive repairs, keeps your vehicle running efficiently, and saves you money on fuel in the long run. Additionally, regular oil filters replacement is a simple and quick process that can be done as part of your regular oil change, making it a convenient and efficient maintenance task.

When Is It Time to Change the Oil Filters

Typically, it's a good practice to change it every time the engine oil needs to be changed. It's easy to track when it was last replaced, plus there's no question that it's still in good condition. However, some car manufacturers allow for oil filters to be replaced every other oil change, typically every 10,000 miles or less. Aside from mileage, what are the signs that an oil filter needs to be changed? Here are ten.

Your maintenance light is illuminated
Many vehicles today are equipped with maintenance minder systems or oil life monitors that let you know when the next oil change is due. Often, you can use this system as a reminder for your oil filters replacement too.

The engine oil looks excessively dark or thick
Monthly, when you check your engine oil level and condition, it should appear brown and feel smooth between your fingers. If it feels gritty, looks black, or it feels unusually thick or sludgy, it's an indication there are contaminants in the oil that aren't being filtered out properly. The oil filters should be swapped out and the oil changed.

Your engine is overheating
Engine oil performs up to 40% of the engine's cooling, but it needs to flow properly through the engine, to the oil cooler, and through the filter. If the oil filter is packed with contaminants, oil doesn't circulate as readily as it should, and the temperature will begin to climb. If it gets up into the red zone or a warning light comes on, it can indicate that the oil isn't circulating well enough to disperse the heat.

Your exhaust fumes are dirty
A clogged oil filters can cause pressure fluctuations in the engine, and a small amount of oil can end up past the piston rings and in the combustion chamber. When it burns, it causes impurities that look sooty and black or brown that come from the tailpipe.

Your oil pressure decreases
Low oil pressure can be caused by a restriction in the oil filters. The gauge or light on your dash can come on or flicker at idle in particular. Low oil pressure can become disastrous for your engine's longevity, and a $10 oil filters could prevent it.

The check engine light is on
If you see a check engine light on and the diagnostic trouble code is p0524, “engine oil pressure too low” or something similar, that indicates poor oil flow. It's usually related to low oil levels or a bad oil pump, but it can also be due to a clogged oil filters.

The oil filter is leaking
If you see drips under your car and you can trace it up to the oil filters adapter, the oil filter leak symptoms often mean it isn't sealing against the flange well. It might have come loose or the seal could be faulty, or it could be that the oil filters body has been impacted and is leaking.

Engine knocking or ticking
When you have low oil pressure or contaminated engine oil because of a bad or clogged filter, the engine is oil-starved and experiences premature wear. The microscopic gaps between moving parts aren't filled with oil any longer, and they knock against each other, causing the noises. This is a particularly egregious symptom that could mean engine damage is already done.

Poor fuel efficiency
Lack of lubrication causes increased resistance inside your engine. It requires more energy to keep it turning as it should, and that requires more fuel to compensate.

Decreased engine performance
Higher resistance also means lower performance levels can be detected, and that's especially true for turbochargers and superchargers on engines. When they're oil-starved, they can fail or have performance-reducing wear.

What Does an Oil Filters Do

From complex climate control systems to one-time-use face masks, filters are utilized everywhere and have one purpose: stop things from getting to the other side. These things can be anything from large dust bunnies to particles of a few microns, depending on what is being protected. Because of this, filters are designed similarly by combining multiple layers of paper, fabric, and/or other materials to stop certain particulates from passing through.

In an automobile, the oil filters captures these contaminants and prevents them from circulating through the engine. Without an oil filter, dirt and other particles much smaller than a strand of hair can and will freely travel into the engine assembly and cause damage due to clogs and other debris. If the engine parts can't move, neither will the vehicle.

Oil filters don't just manage waste but also maintain oil flow. That being said, filters can only absorb a finite amount of pollutants. Once an oil filter is saturated, its efficacy is lost and, thus, you have an unprotected engine.

Oil Filters Test Methods

There are many different standardized test methods used to estimate the performance of a motor oil filters in service.

These tests evaluate such things as collapse strength, burst pressure, single-pass efficiency, multipass efficiency, dirt-holding capacity, pressure-flow profile, impulse-fatigue, hot oil durability, vibration, bubble point and fabrication integrity. The SAE and ISO have numerous standards covering these filter tests.

From the standpoint of oil filters selection, the two most important and commonly quoted test standards are SAE HS 806 and SAE J1858. These two standards are extremely similar to many of the subparts of ISO 4548. The SAE HS 806 standard dates back to the 1950s and has many sections and chapters, including the following:
• Resistance to Flow
• Oil Filters Capacity and Contaminant Removal Characteristics of Full-Flow Oil Filters
• Single Pass Particle Retention Capability Test
• Media Migration Test
• Collapse Test for Lube Oil Elements
• Inlet and Outlet Anti-Drain Valve Test
• Ability to Meet Environmental Conditions
• Installation and Removal
• Mechanical Tests
• Relief Valve Performance

How Does Changing the Oil Filters Improve Performance

Oil keeps engines running smoothly. Without it, pieces of the engine would overheat due to the friction of metal rubbing together. Of course, the oil can only successfully lubricate the engine's moving parts for a certain period of time before it loses effectiveness. Part of keeping the oil effective is filtering out all of the debris. That’s where the oil filters comes in.

If an oil filter is not changed with the oil, a sludge can develop from metal flakes and old oil that has heated and cooled repeatedly over a period of time. Metal particles and old deposits from oil passages are rapidly pulled through the system with fresh, clean oil and a filter keeps them from returning to the system. Ultimately, a new lube filter will keep equipment running smoothly.

A few symptoms you should look out for to determine whether or not your oil and filter need changed are:
• Sounds coming from the engine (like knocking)
• Dark and dirty oil
• Service Engine light
• Exhaust smoke
• Smell of oil in the cabin

If a piece of equipment displays any of these problems, the oil should be checked immediately to ensure proper care. But how do new oil filters improve the performance of vehicles and diesel equipment? They increase the lubrication of the engine which helps with smoother operation, while keeping debris out. Fleetguard lube filters reduce service time by nearly two hours per change and the total cost of ownership by up to 44%!

How to Choose Oil Filters

Price

Some oil filters cost more than others. Just because one is expensive doesn't mean it's great. In the same way, just because one is cheap doesn't mean it's bad. However, conventional wisdom tells us that cheaper usually means lower quality, and expensive typically means higher quality. The price of an oil filter is less of an issue than the components used on or in the filter itself. You'll want to check the components of the filter as best you can to ensure that you're paying for quality, not convenience.

Media

The oil filter media is the actual filtration component that captures contaminants. Some filters come with primary and secondary media so that if the oil isn't cleaned by passing through the primary media filter, particles are still captured effectively in the secondary media filter. It's important to find a filter with quality media, such as resin-free filters, which are less likely to corrode and become brittle from contamination. Cheap oil filters may use cheaper material for the media, which may cause the filter pleats on the cartridge to degrade before it is normally time for an oil change.

Magnets

Magnets are becoming more and more standard these days. Some oil filters will boast having magnets to capture metallic particles. The inclusion of a magnet can help capture metal particles that are filtered through the oil, and thus help clean the oil even more than a standard filter. Not having a magnet in or attached to the oil filter isn't a deal-breaker as the gains are fairly marginal, but every little bit helps when it comes to keeping your engine oil as clean as possible.

Bypass Filter

You'll want to make sure that the oil filter you purchase has a bypass filter so that there's always a way for the oil to reach its destination without being blocked. A bypass filter is as important as the cartridges because if the oil isn't bypassing the filter during a cold start or when the cartridges are full, then the oil isn't getting into your engine, and that could cause serious problems.

Anti-Drain-Back Valve

A proper anti-drain-back valve is necessary to prevent oil from draining back into the sump when the engine is off. Anti-drain-back valves are necessary for inverted oil filters. If you have a hanging oil filter, then an anti-drain-back valve isn't necessary. However, if you have an inverted one, then it's important that the oil filter replacement comes with an anti-drain-back valve to prevent dry starts.

Gasket

This should be common knowledge, but a silicone gasket seal is always going to be the better option over a rubber seal. The reason for this is because silicone is less likely to warp from extreme temperatures (which the oil filter will likely encounter), nor is it likely to break and cause the oil to leak everywhere. If you can ensure that your oil filter replacement comes with a silicone seal, then it means you'll have a much longer-lasting oil filter.

Ultimate FAQ Guide to Oil Filters

Q: What is an oil filter?

A: An oil filter is typically encased in a small capsule with various components inside that are used to filter out contaminants within the oil. The filter's job is to cycle the clean oil back through the engine parts to keep the components running as smoothly as possible. The oil filter aids in all of this is to keep the oil clean so that the oil can do its job of keeping the engine running smoothly.

Q: Where did oil filters come from?

A: The original filter was made of twill-weave cloth, but it was later made from a sturdier material. First, pleated paper, and then synthetic mesh with a louvered design and steel-wire coils. The core concept of the oil filter has stayed the same over the years, but the component designs have changed. The quality of those components can alter how well the filtration system works, how long the filter will last, or how long the oil will be properly filtered and cleaned before making its way back into the engine.

Q: Why do oil filters need to be replaced?

A: Eventually, when the media within the filters is full of trapped particles, the oil can no longer pass through the filter to be cleaned. When this occurs, it means that your oil is no longer being filtered when moving through the bypass valve and back into the oil pan. Each oil filter is fitted with a bypass valve, enabling unfiltered oil to pass through the sump without actually being filtered. This is a safety measure to ensure that oil still makes its way to the engine even when the filter isn't doing its job.

Q: How exactly do oil filters work?

A: We've discussed what an oil filter does and where it comes from, but that still doesn't exactly explain how the filter works or how the oil is cleaned enough to keep circulating through the engine components for thousands of miles before needing to be changed. It starts with the oil pan at the bottom of the engine, where unfiltered oil makes its way through the oil pump and into the oil filters after being pushed through the engine. The oil then cycles through the louvered filtration media to be cleaned and pumped back into the oil pan, all for the cycle to repeat again.

Q: Do more expensive oil filters work better?

A: Generally speaking, spending a little more money on a good quality oil filter offers better filtration and performance. Lower-cost oil filters contain light-gauge material, loose filter materials, and poor-quality gaskets that don't allow the filter to last long. You should research the features and specifications of each oil filter to determine which suits your requirements. An inexpensive oil filter doesn't mean it's bad and a costly oil filter doesn't necessarily mean it's good. The price of an oil filter doesn't tell the quality of parts used in an oil filter.

Q: Do synthetic oil filters make a difference?

A: While you don't have to use it with synthetic oil, there are some advantages. Typically, synthetic oil filters do a better job of trapping small contaminates for a longer period of time (and more miles on your vehicle), meaning less frequent changes. Combined with synthetic oil, it means fewer trips to the shop.

Q: How do I know what kind of oil filters I need?

A: The first step in choosing the right engine oil filters for your car is to consult your car's owner manual. It is important to follow these specifications to ensure that the filter is compatible with your car's engine and oil system. The type of driving you do can also impact the type of engine oil filters you need.

Q: Do oil filters affect oil pressure?

A: An oil filter obstruction or blockage can also cause oil pressure to suffer. Oil filters include pressure relief valves. If this valve is damaged, oil will easily pass right through, reducing pressure. It may go without saying, but it is important to also change the oil filters with each oil change.

Q: How often should you change oil filters?

A: In general, most newer vehicles are designed to run on 6,000 or 7,500-mile cycles for oil changes (the old 3,000-mile cycle is a myth in terms of newer vehicles). Most mechanics agree that it's just a smart idea to have the filter swapped out every time you take your car in for an oil change.

Q: Is it better to have a small or big oil filter?

A: In theory, a larger filter can flow more oil and hold more contaminants assuming the actual filter media is larger (which isn't always the case), but in practice, the OEM size filter will be more than adequate unless you severely neglect your oil changes.

Q: How do you know if your oil filter is bad?

A: Common Signs Your Oil Filters Needs to Be Replaced

Your Maintenance Light is Illuminated.
The Engine Oil Looks Excessively Dark or Thick.
Your Engine Is Overheating.
Your Exhaust Fumes are Dirty.
Your Oil Pressure Decreases.
The Check Engine Light is On.
The Oil Filter is Leaking.
Engine Knocking or Ticking.

Q: Does oil filters improve performance?

A: If a piece of equipment displays any of these problems, the oil should be checked immediately to ensure proper care. But how do new oil filters improve the performance of vehicles and diesel equipment? They increase the lubrication of the engine which helps with smoother operation, while keeping debris out. Fleetguard lube filters reduce service time by nearly two hours per change and the total cost of ownership by up to 44%!

Q: What happens if you change oil filter but not oil?

A: One common question among car owners is whether they can change their oil filters without changing the oil. The good news is that you can absolutely change your oil filter without emptying the oil from your engine. This is because the location of the oil in your engine remains untouched during a filter change.

Q: What does an oil filter do?

A: In an automobile, the oil filter captures these contaminants and prevents them from circulating through the engine. Without an oil filter, dirt and other particles much smaller than a strand of hair can and will freely travel into the engine assembly and cause damage due to clogs and other debris. If the engine parts can't move, neither will the vehicle. Oil filters don't just manage waste but also maintain oil flow. That being said, filters can only absorb a finite amount of pollutants. Once an oil filter is saturated, its efficacy is lost and, thus, you have an unprotected engine.

Q: Oil filters: What does an oil change include?

A: When servicing your vehicle, whether at a dealership, auto shop, or as a do-it-yourself project, the oil filter and engine oil must be replaced together. Although you can top off your engine oil if the filter is still viable, you cannot change the oil completely and ignore the old filter. Draining and replacing old oil is a wasted effort because once the new stuff travels through the used filter, what goes in clean comes out dirty. This is why a standard oil change isn't just about the oil.

Q: Do oil filters make a big difference?

A: When a filter does its job, internal engine components – such as the connecting rods, camshaft and valvetrain – are protected from contaminants that can cause major damage. These components are expensive. Picking the right oil along with the right filter can definitely promote long engine life.

Q: Are oil filters worth it?

A: Our answer, without hesitation, is a resounding yes! Especially for diesel equipment, spending a little bit more on a high-quality, extended-life filter is a simple decision that pays off. They save both time and money, while offering reliable and efficient protection against unnecessary engine wear and tear.

Q: How often to change an engine oil filter?

A: With the exception of electric vehicles, all other cars (including your hybrid) have an oil filter. Regarding routine maintenance, the engine oil and oil filter are items that need to be replaced more often than anything else on the vehicle. Yes, even your tires. There has always been a debate as to how often this is necessary, and there always will be a debate because, well, it depends. A general rule of thumb is 5,000 miles between oil changes but this will vary based on vehicle age, usage, and manufacturer requirements.

Q: Oil filters: What does an oil change cost?

A: Just like oil change intervals, how much an oil change costs also varies. When seeing advertisements for $20 oil changes, always check the fine print. These prices are usually for conventional oil only and at a certain viscosity. Some may or may not include the oil filter or disposal fees either. To be fair, oil filters are generally the cheapest component of an oil change service as the bulk of the final cost will come down to type of oil used, how much of it, and then labor.

Q: How to choose oil filters?

A: Choosing the correct oil filter for your vehicle is of the utmost importance. Most oil filters look very similar, but small differences in the threads or gasket size can determine whether or not a particular filter will work on your vehicle. The best way to determine which oil filter you need is by consulting your owner's manual or by referencing a parts catalog. Using the wrong filter can cause oil to leak out of the engine, or an ill-fitting filter could just fall off. Either of these situations could lead to serious engine damage.
