I've been using Purolator filters for years. For the price, the Purolator One can't be beat.

Out of all of the lineups that filter brands present, Purolator has the most consistent and quality filters I have seen. Filter media is of good quality and construction is second to none. This is my go too filter. Made in America! Hopefully they don’t change a thing.

remember when walmart used to carry the purolator classic, it was cheaper than fram and much better built.

They are excellent filters. I've been using the Boss with Pennzoil Ultra Platinum.

I've been waiting for this review of these filters. I've been using the purolator boss filter since its come out and I love it. It's my go to filter and its great for the price. Thank you for reviewing it.

Advance auto parts ditched fram products for these. A good choice. Much higher quality for a comparable price. I️ have used the classic for my wife’s truck changing every 4K and the boss on my vw turbo changing every 7500 miles. Happy with both.

Good show. You do well in you presentation. Purolator is hard to beat as a line of oil filters. Great quality control. I like the boss, but I also use wix xp, bosch long distance, stp gold and k&n. I buy any of these which are on sale. I go higher-end. My ram has 268, 000. The results speaks for itself.

Best Filters I've ever used. They're my go-to for my vehicles!

I recently purchased an oil filter cutting tool because I wanted to inspect the condition of the Purolator Pure One oil filter I used on my truck with Royal Purple 5w-30. I used the filter for 6,000 miles which is well within its advertised life span. Although the integrity of the filter appeared to be intact I have to say I am disappointed with the quality of the construction. I have seen other videos where these filters have been dissected and they looked really well made which is what motivated me to try the Pure One. I have two major complaints about my filter upon inspection. First, in other videos I have seen of the filters they opened up showed that the filter media started and ended with a metal crimp which is what I prefer, but the filter I had was only glued together. Second, the spacing of the filter media was very inconsistent with several wide gaps. At first I thought this was due to the media being saturated and manipulated by flowing oil during use, but once I cleaned the old oil away I discovered it was due to the position in which the media was bonded to the metal end caps during manufacture

I have seen most of your oil filter videos. I am totally sold on the Purolator. Thanks so much for helping me make up my mind. I am now Tim the Purolator Man.🚘💃

Advanced runs a great deal of 5 qts of synthetic and boss filter for $29.95. Now it's Mobile1 and their best filter, plus a roll of shop towels.

The Boss filter having a thicker shell and base would be excellent for use on a tractor, or truck that might be used where there's more possibility of impacted damage when used on a farm or off road. Better filtering would just be a bonus.

Great video on these filters I've used many different brands of oil filters and never really had a bad experience with any of them but through my experiences and results I now primarily use purolator,wix, or napa,filters. 90% of the time it's purolator.....oh I also use mopar filters as well though I'm a little uncomfortable using them not knowing who makes them, I've used Fram many times and never had a problem with them.

The -14610 and its shorter (2.5" tall) brother, the -14612) also work very nicely in a Yamaha FJR1300 motorcycle. Purolator also changed the coating on at least the PL. It used to be an easy to grip sandy, baby sh1t yellow color. Now, it's the somewhat slippery, dark blue color you see here.

I've researched over and over and purolator is the best looking best filtering best burst strength and best flow rate....i am purolator for good now

The best comparison video is here!

Purolators are great! Tell a friend, and save their car from the Orange Can of Death!

I just bought one because of your review

I recently put in the Purolator Boss filter. WOW. Amazing product it is. I have a 1986 Yugo GV with a 1.1 L, carburetor , high compression engine and always put 10w-40 Castrol GTX conventional oil . I always remembered their commercials on how they were engineered the oil for smaller engines like my car. Their works were always conceiving when you see the intense heat being build up on the combustion chambers and then they broke down. Did one amazing job getting the viewers attention that's for sure. Then I add the Purolator Boss filter to maximize engine protection, boost it's efficiency, extreme reliability in filtering, and the satisfaction rate on how it works. Got to say it was an excellent combination that I recommend for your older model high compression motors. It runs like it's off the dealerships parking lot. Thank you for sharing this video with us. It made me want to buy the BOSS filter and boy, I'm never going to buy anything else until Purolator outdoes itself on developing another advance version to succeed it.

You can get these filters at advance auto parts and they are great

The bypass valve is also made to open on real cold weather starts when the oil is too thick to be forced through the filter. Good video.

I talked to Purolator now owned by Mann + Hummel, they told me that the BOSS although synthetic filters at higher micron level than the ONE. I believe the ONE does 20 microns, whereas the BOSS does 25 microns.

At the time of writing this, Purolator has changed all of their 3 oil filter lineups (regular, ONE, and BOSS) to be rated at an extra 5,000 miles. So the regular is now rated at 10,000 mi, the ONE is rated at 15,000 mi, and the BOSS is rated at 20,000 mi. Would be nice to see an old vs new to see what changed to make them last an extra 5,000 mi.

5:40 found an error, the bypass valve doesn’t open at all just because the media is clogged, that’s not how that works. Bypass valve on a oil filter is designed to open under a specified pressure to prevent the starvation of oil. Most Subaru and smaller high performance engines require 23-26 psi filters, and other engines tends to run between 12-18psi filters. So that’s why it’s important to mention each oil’s bypass pressure in order to understand if the oil will work with a certain car’s spec. This bypass valve is not performance related, but more designed for certain specifications. I believe older PureOne are only rated for 16psi while the new Purolators are 20-30psi. So for engines designed to use 12-18psi, this wouldn’t be the right filters to use because it may potentially starve the engine of oil. And vice versa, if you put a KNN oil filter in a Subaru WRX sti, it’s not going to filter anything for roughly 6-8psi range because Subarus are specified to use a much higher bypass pressure filter and the KNN bypass valve will be opened all the time once the engine operates at a pressure pass its limit.

I just picked up 2 of the Ones for $2.35 and a synthetic filter for $3.99 cuz our kmart is closing down. All 3 for my toyota pickup. I honestly bought them not knowing much about them but i couldnt pass em up

One interesting fact left untold is all three filters have the bypass valve located at the bottom of the filter which is obviously not the ideal location. Many oil filters have the bypass valve located at the top of the oil filter to keep contaminants from reaching the engine during periods when the bypass is open.

Learn something new everyday. I always assumed the anti drain back valve was to keep oil IN the filter. Looking at the design of the anti drain back valve it would support oil from draining from anything uphill from the filter when the engine is off.

I love your filter videos!

The anti-drainback valve really isn't that important if your filter is spun-on upside down (as most are), or spun somewhat upside down at an angle. The oil will naturally stay in the filter due to gravity. So the anti-drainback valve is only really important if you filter is spun on from the top of the motor or on the side but higher-up. That being said, the Purolator is a very good filter for the money and I also believe they make the Motorcraft filters for Ford and those are very good filters as well.

I've always found Purolator products to be of very good quality. 👍

Helpful from from their office: Boss 99% at 40 microns One (blue) 99% at 20 microns Purolator (Red) 96.5% at 20 microns

Been running the boss filter and Valvoline full synthetic in my car works great

David Pearson approves. Pure oil now....pure oil later.

My go to Filter! Purolator One filters are excellent. I got Nissan thats got over 200k. Oil is nice a clean! I also use Wix/Nissan OEM in my other car only because its under warranty.

Thanks for these oil filter videos. I enjoy yours more than some of the other folks. I plan on using the Boss next oil change I do. Been using Mobil 1 full synthetic oil in my car. I would to stay with a USA made filter. Thanks again my friend.

I've used the blue and black for a while now. Good filters as far as I know.

I used the cheap Purolator classic for sometime, and my truck hated me in the cold mornings. I will never go bottom tier, especially one's with rubber anti-drain back valve.

Great review of what I consider to be one of the best oil filters on the market, I was using fram filters until I started seeing poor build and functionality videos, so I switched to Purolator Boss oil filters, along with Pennzoil Platinum (full synthetic) motor oil, and my 15, Silverado runs like brand new, with plenty of horse power response. I would highly recommend to any fram oil filter users to do your engine a favor and switch to Purolator oil filters, your car or truck will thank you for it!!!!!!!!!!!!!!!

You missed one important detail: Is the bypass relief valve using a "soft seat" or a "hard seat." The former refers to when an elastomer gasket-insert is used between the poppet and the plate to form a tight seal so that oil does not seep through when the valve is closed. A "hard seat" is an inferior metal-on-metal seal that always leaks to a certain degree allowing oil to bypass the filter element.

I usually use the “One” on my wife’s Highlander and on my G37S I’ll either go with a M-110 M1 EP or a Purolator Boss.

Purolator has a video on the burst pressure of the Boss filters, its over 600 psi.

I love Purolator classic, been using them for many years. The classic has 96% filtration but boss is 98%. The classic is less restrictive because standard oil thickens over time, whereas synthetic does not. I run the classic filter with mobil1 for 8-10,000 miles no problem. My concern is reduced oil flow and back pressure on the oil pump. Just know that as a filter fills with dirt, it actually filters better. If a synthetic filter gets clogged, the oil bypasses the filter completely. 10,000 miles max for my cars. Combustion engines create dirty oil regardless. Best practice is to replace the filter after 10,000. Oil change is $35 vs an engine costing $15,000

One point not made correct me if I'm wrong, is that the Boss filter bottom hole floor is concaved (recessed) which allows a little more space between the filter floor and where it meets the car. This may allow optimum oil flow with the added space. IDK let me know what ya think.

I´ve watched a lot of your oil filters videos and I can conclude that Purolator Boss would be one of the best oil filters money can buy, I´m asking because I plan to get a top quality oil so I can avoid oil change for a year. I drive 12,500 miles a year so this would be a good filter to combine with the a top quality 100% synthetic lubricant wouldn´t it?

Fwiw their red lowest line now runs 10k miles, blue is 15k & 20k. All have the "Silicon" db valve which is important to have on Air Cooled engines as temps are not consistant do rubber deforms & breaks down more. Been running Purolators over 20yrs. Quality has always been above the rest, others may catch up but its rarely been for very long.

The "one" (blue) is also known as the Ripolator because the filter media gets rip holes in it during use. Lots of pictures online of the issue.

Saw then today at Menard's.

I havent found the actual efficiency in microns. Video tells that the efficiency is 99%. 99% of what particle size?

I love Purolator filters used them for years but I cant seem find them anywhere except Advance Auto Parts

Thanks for the detailed overview!

Thanks, interestingly: I,have never seen any “ PERFORMAX ( made Mexico) PO-167[PZ-167 PENNZOIL??], etc., oil Filters examined!! (my DODGE DEALER USES PERFORMAX in my 2015 Journey Program Oil Change .....?).....** last two I,examined were labeled MADE USA.

Great video as always. Very informative and helpful. Thank you!

You can get a discount at Advanced Auto Parts if you go on line to buy. There is a savings code you put in when paying on line. Then just go in and they hand you your part. Usually 20 percent. No discount for battery's

I use pennzoil ultra platinum in the summer with the purelator boss & valvoline advanced in the winter with the purelator one.

Really good filter reviews! Confirms other info I was able to find on the internet. I will basically stick with Wix and purolator filters for my cars

I use the Mobil 1 EP filter- mite as well try the Boss

I just got a ONE for $7 shipped on Amazon after $2 coupon code.

I'm going to try them today for sure. Just bought the blue filter

Best filters out there! Only ones i use! ill substitute a mobil 1 or wix if i cant get one. Buy mine at meijer.

I love these videos. I have both the 1 & boss for both a 97' Rav4 & 01' Highlander. I'm gonna use the ones & when I'm down to my last filter, which I hope I don't have to use. Imma use the boss as a "save the best for last" bought them all at Amazon once on sale. One was around 5-7. While boss was 11. Normally the one is like 7.20 & Boss is 13 Also for the rav4, I have the premium bosch oil filter as well. To me they're the same as the purolator 1. Kinda how like 7up & Sprite are.

I have a 2015 Chevy Impala limited LTZ with a direct injection motor and that drain back valve takes 3 hours, just to check the oil!! that's how good it keeps the oil up into the head of the engine never had a filter like that in my life PS pain in the ass to check your oil up

Please do nissan filters

Hey, AutoZone just released a new stp oil filter called the max life oil filter. It'd be cool to see a comparison video between the standard stp, extended life, and the new max life filters. Great video, thanks for the great content!

Any idea what the efficiency micron rating of the Boss? I noticed that Purolator rep didn't respond about the efficiency rating. Silence is golden, hmmmm. I still love the Boss. The Ultra is hard to beat. Price and Efficiency. Thanks for the review.....take care

I pick up a boss filter and pick up a fram ultra, and boss feel more heavy and more heavy duty and feel more sturdy then the fram ultra, with discount code by buying online at advance auto part, its my only high end filter for now.

First.. No question that Purolator makes great filters. However, If you think about it, the mileage ratings are just for reference. The number of miles traveled vs the volume of oil being pushed through the filter is impossible to accurately predict due to different GPM ratings between vehicle oil pump, moving vs idling ratios, etc. Of course, the higher the "mileage rating" the longer lasting the filter may be, BUT my vehicle's engine run time & oil volume flow over a 10k mile period will likely be significantly different than yours. (Not to mention it's a real bad idea to go beyond 5k miles between oil & filter changes on the typical daily driver vehicle.)

Gave the boss a try very impressed oil is still clear as can be @about 1500 miles. I'm using Mobil1 5w30 High Mileage Extended Protection formula. Mostly highway miles runs great. I was using a K&N and it was dark by the time 1000 miles passed

I work at advance and we almost always have the deal on 5 qt full synthetic your choice of Mobile 1 Valvoline or Castrol with your choice of Mobile 1 K&N or Purolator Boss filter whenever a customer ask what I'd use i always say Valvoline with the Purolator Boss 💯 i think mobile 1 oil is fine but never Pennzoil or Castrol and NEVER a fram filter

Exactly my thought. A low-end or no-name oil filter is good for 5000 miles. No more. If you run dino or semi oil and you have a clean engine, you don't need a pricier filter as long as your oil change interval is under 5000 miles. I have never had an engine that requires synthetic, but my thought is, use a low-end synthetic and change it more often, maybe even every 4000 miles. The price differential between dino, semi and low-end synthetic has just about disappeared. In fact, at this point all oil is semisynthetic to a degree because the carrier oil the additives come in is synthetic.

Thanks for the review very informative

Purolator also makes the Ford Motorcraft Filter

One gripe... Anti-drainback isnt so all the engine oil drains back into the filter... How can 5 quarts of oil drain into a 1 quart filter???? Stop saying that. It's there to prevent the oil in the filter from draining back into the engine, so the filter doesn't have to refill each time you start the engine.

Great video! First time watching one from your channel. Very nice job, might subscribe!!! Thumbs up

What many videos do not show is how Motorcraft Filters are one of only few companies using a thread end bypass, Wix, Napa, and Royal Purple all had outstanding design and when they got bought out, the designs changed and in my opinion they are a cheap design. No longer made with highest quality. Royal Purple Filters, Napa Gold and Wix have all changed from a nice steel base plate with thread end bypass, Silicone ADBV, evenly spaced holes and steel coil spring, solid canister casing. It would be interesting comparison how they have changed. Now Purolator is better than those. I currently use Motorcraft although I know they use a leaf spring and the Purolator is a decent design, the Boss is nice and it shows filter media is better than Motorcraft. Not a fan of dome end bypass. Many new oil filters displayed in videos don't even come close to what RP and Napa Wix used to be years ago. The new ACDelco E core is an embarrassment. Why do these companies think they can change a proven design and still have a loyal following for a cheaper product. They must think customers don't notice. I expected K and N to be higher quality, the dome end bypass design is cheap and does not look built with durability.

I'm no rocket surgeon but just saying, polyester is the definition of a synthetic material. Byproducts from oil and gas production polymerized....

to me Purolator One is the best oil filter ever made I change the oil and filter every three months or every three k miles never let me down!!!

Can I use the red filter for full synthetic with a 3k mile oil change? I know it's not the greatest, but I usually do 3k mile oil changes anyway. Doesn't seem like it'll hurt, thoughts?

I currently have a Wix XP and a Purolator Boss filters. I am going to run Pennzoil Ultra Platinum 5w-30 engine oil. Any comments on what filter is "better" ?

ABSOLUTELY THE BEST OIL FILTERS...HANDS DOWN. BRAVO PUROLATOR!!

you say CLASSIC for conventional/high mileage and ONE for high mileage and BOSS for full synthetic. Does this mean I shouldn't use ONE or BOSS for conventional?

Looks like the classic filter is the same as the ONE except for silicone ADBV. I use the classic because I change my oil every 2500-3000 miles. That's around the mileage I can't see my oil dip stick level lines through the oil. The oil has more life but not up to my standards. My mechanic burns the old oil for heat so he gets the old oil.

After working for PepBoys for almost 2 years I've put these on a ton of cars. They seem to be some great quality filters and from all the crappy Fram filters that I've had to fight with to take off, these are much more reliable. We even have a line of filters called PurolatorTech which is what the service side uses for the basic oil filter. If you could get your hands on one and compare it to the other three it would be appreciated because I've always wanted to see their composition.

"To the the burst pressure on this..." :-D If this shell would burst, something else probably blew up first under the hood!

purolator classic filter--magnatec full synthetic oil--4000 mile change-cost 26.00- do it myself-peace of mind--i cant go wrong

I like the Purolator one for the price.

Hey man, nice video. Very detailed review 👍! Have you thought about reviewing Napa Oil Filters? Im sure that'll make an interesting review 😆. Keep up the good work, we (the viewers/subscribers) appreciate it.

Very nice video. Thank you.

I have a good idea a anti drain back red silicone washer with a 3-5 psi coil spring under it for the anti drain back system.

Good video. However, "rubber" is not a definitive description. It usually implies Natural Rubber which typically has no chemical resistance to motor oils. Synthetic elastomers vary greatly in chemical resistance. Some are very chemical resistant to motor oil other are not. Some have chemical resistance to motor as good as silicone formulations and may have better physical properties. Fluoroelastomers have very good oil resistance and high temp ratiings and they are usually black. So it is best to check with the mfg of the filter to determine the exact elastomer.

Doesn’t MANN Hummel own Purolator? Along with wix

One more thing. I am now running full synthetic, high mileage oil. Would it still be ok to use the Boss or the One ? Any comments I would appreciate. Thanks to all.

Very nice review. Thank you.

Why i did not see this video before!! OMG

Can you make a video comparing Purolator oil filter vs Carquest oil filter? Thanks

Best mid range filter, Purolator One or Bosch?

How does a filter know how many miles you drive on it. Pleat area is what matters and micron rating.

There's way more going on inside of an oil filter than I thought I really hope this makes sense to you because I'm butt fuckingly high right now

When you say high mileage for the red filter do you mean high mileage synthetic blend oil?

How are these compared to Amsoil filters?

Do you happen to have the micron filtration rating for each of the filter media? (or did I miss that?) Thanks!
