I'm dubious, I'd wait to see some detailed testing on how small of particles it catches, i.e. the micron rating.

No thanks. There would be no way to know if you actually got it clean.  20 micron particles are pretty hard to see.  Besides, $250 will buy me 15+ of the most expensive disposable filters on the market that probably flow and filter just as well or better.  At 5000 mile OCI each, that's 75,000+ miles.  At 7500 mile OCI, it's over 112,000 miles. The math just doesn't add up for me.

These filters have been out for awhile now, Personally i do not trust this style of filter. Just like @Mike GMC i can by 15+ of disposable filters and have peace of mind on my motor. @garagerog I believe that K&N states it on their website, and from what i remember it not great.

Bad as the gimmick in the 90’s when the military was using rolls of toilet paper and Bounty paper towels in canisters on their vehicles for oil and hydraulic filters.

 

Somebody made money off it.  Sure they ran. For awhile.

I run the K & P stainless cleanable as the first pass. 30 micron absolute. AMSOIL bypass filter as the secondary. 98.7% absolute efficiency at that 2 micron. By the time it's done the oil is cleaner than when it was in the bottle.

Personally I don't trust K&N for anything, their better flow air filters comes because they don't filter as well, and that scares the heck out of me when it comes to an oil filter. I'll pass.

·        Lifetime (steel mesh) oil filters are not cost effective and there is no data that shows effectiveness.  Does not compare to any other filters, really any better, questionable.  Instead of throwing away a disposable oil filter you now have to dispose of cleaning solvent.  Also, if the oil gets changed somewhere is it likely will get throw away.

I’ve used lifetime filters in the air box and in the cabin filter. I’ve since switched back to the throw aways because I don’t feel like even on my best jobs cleaning those that I got close to how clean a brandy new filter is from the factory. And it’s way more time consuming for the lifetime ones. It’s a PITA I don’t want anymore. And when I think about it like that, I’d never even try one for the engine oil. Some stuff should just be done the old fashioned way. Hahaha

I have been running a K&P stainless mesh filter for the last two oil changes.

 

I was concerned about the efficiency of the thing so sent an oil sample to Blackstone labs.

 

I told them that I was running a stainless mesh filter and requested specifically that they check for excessive particulates.

 

The test results showed normal.

 

Still not sold on the efficiency of the filter, I will send another sample at the next oil change

 

I use brake clean and then simple green, then hot water and finally air – all applied from the inside of the filter - to clean the filter. I’m retired so the extra time is no big deal and I can see what the filter has trapped with the mesh and the built in magnet.

 

I have read that paper filters - because to the structure of the paper - can pass much larger particles and still be rated at smaller micron ability

 

I have read through numerous strings on oil filters and efficiency down to ten microns but assume that the testing is done on new filters.

 

According to the information on the K&P site, their filters flow a lot of oil so rarely bypass even when cold.

 

My question is that when the filters get loaded or contaminated with water such that the passage of oil becomes more restricted or when the oil is cold, do they bypass more often such that efficiency is reduced?

 

Does anyone know of testing that was done on filters in real world scenarios?

Grumpy Bear, what type of bypass do you have set up with your K&P filter?

 

Thanks

Tim I have a confession to make. When I wrote this I had all the bits and pieces except the bracket and the valve cover bung to plumb the entire system and was in fact using the K & P as a stand alone so...wrote the reply as if it were done when in fact is was not, fully anyway. After finding the bung was not available for my application and my source for the custom bracket going out of business I pulled and stored the K & P after maybe a half dozen oil changes. I've been running a Purolator Pure One ever since. 

 

I haven't given up on the project just on back burner. I want it to look factory. Picky I am. 

 

So why pull it? Because the difference in motor life between 30 micron and 10.5 micron at 99% is about a factor of 2. If and when I get the AMSOIL bypass is play that could double again. (GM filtration study)

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉

      I gotta say, I'm enjoying your narration. The troubles you've been having are amusing as you describe them. It's good to see that you're finally getting some satisfaction out the old beast though.

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.
