For some vehicles like the Honda Civic, this filter can be a little hard to remove as there does not seem to be a very good grip for a wrench. However, this should not be a deal breaker given its efficiency and superior build.
Oil filters will come in many types, and so before you decide to buy any of them, you need to understand what they are all about and what suits your vehicle. Here are 6 of the most common types of oil filters.
Mechanical oil filters are the standard type and also the most common.
It is the kind that uses filtering media made of bulk material like cotton waste and pleated filter paper to hold the contaminants.
With this oil filter, the tiny contaminant particles are suspended when they pass through the media.
But the greatest shortcoming of this mechanism is that as more and more contaminants accumulate on the filtering media, the flow of oil is affected.
If you are using a mechanical oil filter, you will need to replace it more frequently. For some types, you only need to replace the filtering media but for others, you will need to take out the entire filter and put in a new one.
Cartridge oil filters are one of the oldest types, and they consist of a permanent housing and with a replaceable filtering media.
But, the design has been improving and now these filters also feature a spin-on which aims to improve their performance and convenience.
Although the design and filtering material on these oil filters may vary, the best cartridge oil filters use a synthetic material for filtering.
This media offers more long-lasting filtering than traditional filter paper or cardboard.
As the name suggests, magnetic oil filters make use of a magnet or electromagnets to suspend the ferromagnetic or tiny metal parts from the flowing engine oil.
The best thing about magnetic oil filters is that you only need to clean out the suspended contaminants to restore the filter to a good working condition.
However, it is also important to note that this filtering component can have some harmful effects.
Sedimentation oil filters are the types that are also often referred to as gravity bed oil filter.
These filters work by allowing the suspension of the contaminants that are heavier than the oil.
The contaminants are maintained at the bottom of the filter using the natural occurrence of gravity.
While these oil filters work good enough, they are not always the most efficient in trapping all the contaminants on the oil.
With a centrifugal oil filter, you also use natural occurring forces. However, instead of gravity as in the sedimentation oil filter, it makes use of centrifugal force.
Centrifugal force is the force that comes from rotating devices.
During the filtration, the pressurized oil will go through the centrifugal filter's housing and through the rotor which has two jet nozzles that settle oil in the inner house to get the drum rotating.
The oil will then pass through the bottom wall of the housing while the contaminants get stuck there.
But you need to clean the housing on these filters from time to time to prevent a heavy build-up of contaminants, which can cause the drum to stop rotating and hence allow unfiltered oil to pass through.
The high-efficiency oil filters are a type of bypass filter, which is designed to allow for relatively longer oil drain intervals.
These oil filters have a 3-micrometer pore size that helps to minimize engine wear as a result of continuous oil filtering.
For many vehicles, the drain interval can extend by up to 10 times when using a high-efficiency oil filter.
Mobil has been making oil filters longer than many other companies, and it is known for making high-quality and relatively affordable filters that deliver high mileage like Mobil 1 M1-110.
On average, their oil filters will have an efficiency of around 99.6 which is good enough for most vehicles. And they have a high capacity as they can capture up to 28 grams of engine contaminants which helps to lengthen the change interval.
Because most of their filters use aluminum canister or housings, they can also withstand more operating pressure.
Fram makes some of the cheapest oil filters on the market like Fram XG7317. Hence if you are shopping on a tight budget but still want something high-quality, high-performing and efficient, Fram is a good oil filter brand to buy.
With Fram oil filters, you can pay up to 50% less than what you would pay for Royal Purple or Mobil.
Their filter will often provide a decent efficiency of 95% and a change interval of around 5,000 miles which is still quite good given the cheap price tag.
Royal Purple is famous for being a performance-oriented brand and also for producing long-lasting oil filters.
They have a line of extended life oil filters similar to what Mobil produces, and they also have thicker shells for durability and to ensure they can withstand high pressure.
With a Royal Purple oil filter like Royal Purple 10-2835, you will get an efficiency of up to 99% with filtration of as small as 25 microns.
Dry starts will also not be a problem when using a Royal Purple oil filter as each has an anti-drain back valve to prevent them.
With Motorcraft, you get an oil filter brand that makes use of innovative design to offer great multi-pass filtering efficiency. Their highly-efficient filters are designed to filter out carbon, abrasives, dust, and bits of metal.
There are pressure relieve valves on their filters that ensure uniform oil supply even under cold temperatures.
Durability is also guaranteed with Motorcraft filters as they come with a robust steel casing that is painted to prevent corrosion and rust.
ACDelco is another great oil filter brand that is known for making highly efficient filters. Their filters like the ACDelco PF2232 have an efficiency of 98% at 25-30 microns thanks to the multilayer filtering nets that provide excellent filtering.
The aluminum shells and thermosetting adhesive seal on the filter's base give ACDelco oil filters a high burst threshold and great performance in any weather.
These filters will fit most cars, light-duty trucks and SUVs, and are also quite affordable when compared to other top brands.
You can be confident of ending up with the best oil filter if you keep the following points in mind when shopping.
Like everything else that comes with your vehicle, oil filters are available in different sizes, and so you need to choose what fits your car properly.
For some cars, any oil filter will work provided it fits the space left for the filter by the manufacturer while for others you need something that properly matches the car.
Your car's manual should tell you the right oil filter size and model number. If by any chance it does not, your mechanic should help with this or you can search online or contact the manufacturer.
Oil filters will come with different membranes or filtration media. Because this membrane is what does the actual filtration it is important to make sure that you pick the best. The three most common ones are cellulose, synthetic and micro glass.
Cellulose: The disposable types of oil filters like ACDelco PF2232 are often made of cellulose filtration media. Cellulose can suspend contaminants that are between 8 and 10 microns large and will clean up to 40% of the engine oil.
If you are using an oil filter with cellulose as the filtering media you will need to check and replace it after every 3,000 miles.
Synthetic: Synthetic media are what you are likely to find in the high-quality oil filters. This filtration media is designed to remove 50% of particles that are between 20 and 40 microns large and up to 24% of those that are between 8 and 10 microns.
With the synthetic media, you will need to check and replace your oil filters every 5,000 to 7,000 miles.
Micro Glass: Micro glass is the preferred filtration media for the high-end oil filters. This filter media is made from fibers that can be up to ten times finer than cellulose fibers.
With micro glass filter such as Royal Purple 10-2835, there will be less restriction to oil flow as a result of contaminant buildup. Hence,you will only need to replace the oil filter every 10,000 miles or after 2 to 5 years depending on which comes first in your situation.
For oil filters, the capacity will refer to its ability to hold contaminants, and it is determined by the filtration media used and the build quality.
The larger the capacity the longer the filter change interval and hence the better it will be for you as it will be a long time before you need to worry about buying a new oil filter.
Most oil filters will provide a capacity of at least 10 grams, and if the capacity is reached the bypass valves come into play to allow the unfiltered oil to pass through.
Some high-capacity ones like Mobil 1 M1-110 will deliver up to 28 grams capacity, which makes it more long lasting.
It is vital to make sure that the oil filter you buy is made from the best quality material as this will ensure that it can withstand high pressures and is also durable enough.
Metals like steel and aluminum make some of the best oil filters and they will not wear out as fast as those made with cheap plastic parts.
Note that buying an oil filter with a low-quality construction is not a good idea no matter how cheap it is as it will wear out fast and cost you more money in the long run.
An oil filter is something that you should be able to replace on your own without any help from a mechanic. And this is regardless of whether you are good with cars or not.
However, they are not all easy to use or install. Hence before you buy any oil filter you should make sure that it will be easy for you to install.
Watch out for factors like the size, weight and housing design as they will all affect the ease of use. And also make sure that whatever oil filter you buy comes with installation instructions.
A: Filtration efficiency is what makes a good filter. Here, something that can trap at least 98% of contaminants is perfect. However, the build quality also matters, and something with a heavy-duty steel housing is a good buy.
A: No, some filters are designed to work with conventional oil only, while others are for synthetic oil use only and some can work with all oil types.
x Do I Need to Change Oil Filter Every Time I Change Oil?
A: No, some oil filters have a service life of up to 15,000 miles, while oil is changed every 3,000 miles. However, most experts will recommend you change the filters every time you change oil.
A: It becomes clogged over time, and hence reducing the oil that gets to the engine, which in turn can cause severe engine damage. Also, the filter media can develop holes, which will then allow contaminants to get to the engine and cause damages.
A: Every time you replace your oil. If not possible, you should replace the filter according to the manufacturer's recommendations.
