Do You Need To Use The More Expensive Oil Filters
For near of us, oil filters are probably something we never think most.
We know that when we modify our engine oil, the oil filter also needs to be replaced likewise. What kind of filter should your mechanic use? Does it even matter? An oil filter is an oil filter, correct? Incorrect! Nowhere else in the automotive parts world exercise we run into such a range in quality – from the practiced to the very bad – than we do with oil filters. You might be surprised to know that many and so-called automotive "professionals" are installing oil filters which don't even come close to the caliber of your vehicle's original filter.
Across the country, this negligence is costing Canadians hundreds of thousands – possibly fifty-fifty millions – of dollars every year in the grade of excess engine wear and vehicles that deteriorate before they should. How do these 2nd-dabble "mechanics" get abroad with this? We'll explain that at the stop of this article.
one) The filter media is what really traps dirt and contaminants. It is supported by the end caps and centre back up tube.
2) The bypass valve redirects oil effectually the oil filter in the upshot that the filter becomes clogged.
3) The anti bleed-back valve prevents oil draining back into the engine when it is shut off, in order to forbid dry starts, which are the leading cause of engine wear.
But now, allow'south get right to it: We wanted to do something totally cool and cutting open up eight of the nigh popular oil filters on the market, to show you how they work and the differences between them.
To keep things consistent, nosotros purchased all of the filters to fit the aforementioned popular vehicle; a 2014 Ford F-150. Like well-nigh modernistic vehicles, this F-150 is equipped with an oil life monitor that calculates oil deterioration based on how and where you bulldoze. Drivers who frequent the highway and drive regularly will see the oil life monitor stretch their oil changes out to about fifteen,000 km, since this type of driving is easier on the engine oil. Drivers who do mostly brusque trip and around-town driving volition notice their "change oil" message coming upward closer to 6000 km.
Because – like near modernistic vehicles – the F150 has an oil change interval longer than 5000 km, its oil filter requires certain features proceed working properly all the way up until the adjacent oil change:
- For any oil change interval longer than 5000 km, the filter'south anti drain-dorsum valve should be made of silicone instead of cheap nitrile material.
- The internal construction needs to be strong plenty to final through hundreds of rut cycles.
- The filter media needs to be dense and plentiful enough to continue trapping dirt through the entire life of the filter, without plugging. One time the filter is plugged, it will enter "bypass manner" where it stops filtering your oil. This is when engine article of clothing really starts to take identify quickly!
Without farther ado, here are the oil filters that we tested, and how we ranked them from best to worst!
1st Place: Wix (Napa Gold)
Internal parts showing the all-metal interior construction, silicone anti bleed-dorsum valve, and coil spring.
Filter element and thick steel base of operations plate.
Close up of the filer chemical element showing the density and even pleat spacing.
Inside the filter chemical element, showing the screw-wound steel core and the integral bypass valve.
Hither's the other side of the filter element, showing the outside of the bypass valve. On the left, the quality bleed-back valve seals to the base of operations plate.
Wholesale toll (to a professional shop): $6.51
Filter media: Drinking glass enhanced cellulose
Filtration efficiency: 99% of particles above 23 microns; 18 gram chapters
Anti drain-back valve: Silcone
Recommended modify interval: 6,000 – 16,000 km or 1 twelvemonth
Truly uniform with this vehicle: Yes
Full disclosure: These are the oil filters that we use in our shop. For that reason, though, it was reassuring to open the filter upward and discover such quality on the inside. The filter just impresses when you take it apart.
The Wix filter uses the best filter media of all the filters in our comparison, capable of trapping the about dirt and contaminants. Structure of the filter element is very solid, with metal finish caps and a metal seamless, spiral-wound centre core reinforcing the media. The bypass valve is all metal too, and looks very good. The anti-drainback valve is made of silicone, and features a robust design. Finally, everything is held together with a metal coil spring; a design that is more often than not considered better than the steel wave springs institute in most oil filters.
second Identify: Ford Motorcraft
Internal construction showing the good quality filter element; all metallic construction; and silicone anti drain-back valve.
This filter features a thread-end bypass valve. This is becoming more popular but well-nigh filters yet feature a bypass valve at the other finish of the filter.
Another shot of the filter element. The glue job on the Motorcraft filter is a bit sloppy; nosotros wiped a fair bit of glue off the stop caps before taking this photograph, and at that place'due south still some showing.
The thread-cease bypass valve is built into the filter cease cap. Inside, the filter features a spiral-wound seamless steel core.
Bypass valve and silicone anti drain-dorsum valve on the good quality base plate.
Wholesale cost: $9.92
Filter media: Cellulose and polyester alloy
Filtration efficiency: 80% of particles above 20 microns (Ford advertised); 93% at 20 microns (independent testing); 12 gram capacity
Anti drain-back valve: Silcone
Recommended modify interval: 12,000 km or 1 year
Truly compatible with this vehicle: Yes
This is the OEM (manufacturing plant) filter for this truck, and the filter that all others should be compared to. Information technology'southward a very skillful quality function, every bit you'll meet in the photos.
3rd Identify: Fram
Internal construction showing the fiberboard-reinforced filter chemical element and silicone "combo valve".
Shut up of the filter element; definitely not every bit strong every bit our other filters, with less filter material.
This filter uses a cost-saving "combo valve" that combines the anti drain-back valve and bypass valve into 1 part.
Wholesale cost: $6.12
Filter media: Glass enhanced cellulose
Filtration efficiency: 95% of particles above 20 microns
Anti drain-dorsum valve: Silicone
Recommended change interval: OEM (encounter notes below)
Truly compatible with this vehicle: Yep, just not your all-time choice.
If we had done this comparison several years agone, Fram oil filters would have ranked very near the bottom of our list. However, the Fram make is now being manufactured past a dissimilar company and the filters accept received major upgrades, including a much better filter media and a silicone anti drain-back valve.
The construction withal isn't great, though: Fram filter elements still feature fiberboard end caps and a lot less filter media than most of the other filters in our comparing. The heart core of the filter is steel, but it's not the strong, seamless design found in the filters above. Fram states that these filters are designed to last for any manufacturer-specified oil change interval, and we can't really disagree. While this filter does technically check all of the boxes in terms of Ford's requirements for this truck, the to a higher place filters are probably a better choice.
Necktie for 3rd: Motomaster
We picked up i of Canadian Tire's new Motomaster oil filters for this comparison, merely to discover that they are manufactured by the same company (and are exactly the same) every bit the Fram filter. The Motomaster filter is cheaper, though.
4th Place: Pennzoil
Internal structure including the all-metal filter chemical element; nitrile drain-back valve and spring.
The filter element includes a stiff spiral-wound centre core.
Very like filter element to the Ford OEM filter, with the same sloppy mucilage job - but the bypass valve moves to the other end of the chemical element.
Lesser side of the filter chemical element showing the unique integrated bypass valve, and the nitrile drain-back valve.
Wholesale cost: $4.12
Filter media: Cellulose
Filtration efficiency: 95% of particles above 20 microns; 13 gram chapters
Anti bleed-back valve: Nitrile
Recommended change interval: Up to 8,000 km, 3-6 months
Truly compatible with this vehicle: No
These are the filters used by one of Canada's largest quick-lube chains, who likewise operates within a major department store.
The Pennzoil filter is actually a very nicely constructed filter; manufactured past the same company that builds the OEM Motorcraft filter. The internal construction is all metallic; including a stiff spiral-wound centre core. Filter media is of practiced quality, and at that place'south lots of it. The filter features a conventional spring-operated bypass valve as well. Unfortunately, the filter merely lacks the features required to go the distance and survive Ford'southward recommended oil change intervals. The Penzoil filter would make a good selection for someone on a budget, who is looking to alter their oil every 5000 km or so.
5th Place: Napa Proselect
Internal construction showing the all-metal filter element construction; coil spring; thread-end bypass valve; and nitrile anti drain-dorsum valve.
With it's stiff spiral-wound heart core, this filter element looks identical to the Wix filter - but features a lower quality filter media.
Close upwards of the filter element.
Like the Motorcraft filter, the Proselect uses a thread-end featherbed valve. This one isn't part of the stop cap, though, which could cause some leakage past the valve.
Close up of the featherbed valve and inexpensive drain-back valve.
Wholesale cost: $3.99
Filter media: Cellulose
Filtration efficiency: 95% of particles above a whopping 29 microns; 13 gram chapters
Anti bleed-back valve: Nitrile
Recommended change interval: 5000 km recommended; 8000 km max
Truly uniform with this vehicle: No
This is an economy filter that usually isn't sold to the public, but only to automotive professionals. (Doesn't that seem kind of backwards?) Many of our local competitors employ these filters, so be sure to ask a few questions earlier your next oil change. This aforementioned filter is also sold under the Parts Chief make in Auto Value stores, and equally the Wix Pro-Tec in some American chains. It's really hard to rank such a nicely-built filter below the Fram twins above, but we had to give the nod to Fram's better filter media and silicone anti-drainback valve. While the Proselect features the same loftier-quality construction as the Wix filter, it offers much lower filtration efficiency and uses a inexpensive nitrile anti-drainback valve.
This is a great example of how merely because two products curl out of the same mill; that doesn't mean they are of equal quality. The Proselect filter is manufactured by Wix Filtration Corp, who of grade builds the Wix filter above. However, the Proselect filter is manufactured to very different standards; Wix says it traps 50% less clay than their standard filter, and recommends an oil modify interval of just 5000 km with the Proselect.
6th Place: Luberfiner
View of the internal parts, showing all of the cheapest possible components have been used. Note the nitrile rubber "combo valve" and the fiber/newspaper filter element end caps.
View of the plastic interior cage that supports the filter media. This is a cost-cutting attempt just results in a cadre much weaker than the metal cores in our other filters.
Older versions of these filters had even cheaper plastic cores, and were very prone to filter media accident-outs like this i. This will allow unfiltered oil through the engine.
Newer versions of these filters still experience like failures. This media blow-out came after merely 5100 km of service.
Another shot of the nitrile "combo valve" that serves as a byass valve and an anti drain-back valve all in one. These valves are designed for a maximum service life of 5000 km, and in testing have started losing drain-back function as early as 4000 km into the oil change interval.
Close upwardly of the filter media. This is an innexpensive single layer all-cellulose design.
Defense version of this filter, another make that -perplexingly - is ordinarily only sold to automotive "professionals".
Wholesale price: $2.01
Filter media: Cellulose
Filtration efficiency: Not published
Anti drain-back valve: Nitrile
Recommended change interval: 5000 km recommended; 8000 km max
Truly uniform with this vehicle: No
These are the oil filters used by Airdrie's second-busiest quick lube chain. They are manufactured by Champion Laboratories simply like our Service Gnaw filter below, and on the inside are basically the same as that filter. You'll as well notice the same filter on auction under the budget Defence force make, typically non sold to the public. (At to the lowest degree Luberfiner lists the correct size filter for our 2014 F-150, though. You lot'll have to keep reading…)
These are an "economy" filter in every sense of the word, with a cheap cellulose filter media; fiber/newspaper filter element stop caps; a plastic muzzle reinforcing the media instead of a metal tube; and a nitrile "combo valve" that doubles as both a bypass valve and an anti-drainback valve.
We practice not recommend using oil filters like this unless you have no other option, and the side by side oil alter should exist performed no subsequently than 5000 km; regardless of what your oil life monitor indicates.
Terminal Place: Service Champ
The Service Champ filter is much smaller than the others in our comparison. This isn't a good start.
Screenshot of the Service Champ website showing this as the "right" filter for our 2014 Ford F-150.
Within this filter, every possible action has been taken to reduce costs. Note the inexpensive filter element with fiber/paper end caps and a plastic core, and the nitrile rubber "philharmonic valve".
A better await at the plastic eye core. This does not support the filter element well, and in testing has been shown to permit "blow-outs" or holes to form in the filter media, where unfiltered oil can laissez passer through.
Older versions of these filters had even cheaper plastic cores, and were very prone to filter media blow-outs like this i. This will let unfiltered oil through the engine.
Newer versions of these filters nevertheless feel similar failures. This media blow-out came after only 5100 km of service.
Shut up of the filter chemical element. We didn't even bother measuring the surface surface area of this filter, considering it is and then much lower than the other filters.
Close up of the cost-saving "philharmonic valve": a bypass valve and anti drain-back valve all in one. These take not proven reliable or accurate plenty for any carmakers to use them in their OEM filters, so nosotros don't utilize them either.
Service Gnaw filter element vs Wix element. Not only is the Champ filter chemical element much smaller, but its pleats are most half every bit deep also. It's obvious that the economy filter won't perform nearly every bit well every bit the Wix.
Wholesale cost: $1.62
Filter media: Cellulose
Filtration efficiency: Not published
Anti bleed-back valve: Nitrile
Recommended modify interval: 5000 km
Truly compatible with this vehicle: Definitely not!
These are the oil filters used past the Airdrie'southward busiest quick lube chain, with two locations here in boondocks. (We actually bought this filter from one of those locations.) These super-budget filters are non for sale to the public, and non available online.
This is an interesting filter to include because it illustrates a common lube store problem that we see all the time. Do you lot detect how much smaller this filter is than the others? This isn't a mistake; information technology's considering some lube shop filters are listed by their thread and gasket size, not by the vehicle. That means if it will physically spiral onto your vehicle, information technology gets used; with no consideration to the media size, bypass valve setting, etc. Every bit you'll see in the screenshot from the Service Champ website, this is actually the filter listed to "fit" our 2014 Ford F-150.
On the inside, the Service Champ is very much an economic system filter, where every corner has been cut in order to reduce costs. Non simply is this filter a poor choice for whatever oil change interval longer than 5000 km, only it will also do an inferior job protecting your engine during the time that it is installed. As one automotive writer recently said, "If you don't care about your engine, so this is the filter to utilize."
So, why practice all these cheap filters exist?
Nosotros hope you enjoyed this presentation! Information technology'southward interesting to annotation that out of the eight filters we purchased, we take two filters which we'd definitely recommend for this Ford F-150; ii that sort of do the job; and 4 that we definitely wouldn't recommend. Why are so many folks in the manufacture installing these inferior filters, and how do they get abroad with using a conspicuously inferior product?
The "why" comes down to consumers: Some drivers are concerned chiefly with toll, and less concerned most quality or the longevity of their vehicle. Other driver's might not realize there'south a difference, and haven't learned to ask their shop what kind of oil filter is being installed. Nosotros hope this article helps with this!
The "how" – equally in how shops become abroad with installing an inferior filter – comes downward to the fact that engine article of clothing happens slowly over fourth dimension. Engine wear is invisible to the consumer, and doesn't testify itself until years downwards the road. It'due south the departure between your timing chain lasting 250,000 km, or lasting 150,000 km – or your whole engine lasting 500,000 km instead of 300,000 km. By the time a failure has happened, the oil filter has been replaced dozens of times and yous'll never exist able to point the finger at a specific part.
Are cheap oil filters truly "Warranty Approved"?
Lots of quick lube shops have a big sign outside saying their services are warranty approved for newer vehicles. Usually, that claim comes with a big asterisk. In the instance of our F-150 here, your warranty is unremarkably still maintained as long every bit you change that cheap oil filter every 5000 km, since that'southward all it is designed for. But if you follow the F-150'south oil life monitor and change the oil at fifteen,000 km, you're no longer protected. This is why most lube shops volition install a window sticker with a recommended 5000 km oil change, regardless of the vehicle and its actual requirements. (You lot can see how it might be less expensive in the long run to just purchase a better oil filter!)
The makers of these economy oil filters all offering some sort of guarantee, where they pledge to repair any engine damage that results from use of their filters. Still, every bit we discussed above, engine vesture happens slowly and that oil filter is unremarkably long gone by the time a failure happens. In the event of a more than sudden failure, the guarantee is still mostly meaningless considering really proving what caused an engine failure is adjacent to impossible. These companies likewise know that nigh consumers will never spend the thousands of dollars to have their engines disassembled on the off chance the filter manufacturer might pay to have it repaired.
As engines become more complex, automobile manufacturers are starting to care a piddling more than about what type of oil filter you install on your vehicle. We know of two cases, just within the last year and within Airdrie, where a customer was denied warranty on their engine because a depression quality economy oil filter was installed. Is saving a few dollars on your filter worth the risk? We don't recall so.
