What's in your filter? Media types explained

What is the take home message with this thread? I'd like to know the "best bang for my buck" oil filter. I am a happy owner of a 2002 Lexus LS430 with about 100,300 miles. I'd like this car to last me another 10 years. I plan on changing the oil every 5000 miles. I put a "rare earth" magnet on the drain plug and on the crankcase next to the drain plug to "catch" all the metal pieces, whatever that's worth.
Depends on what's available for your vehicle really. The OG Fram Ultra was a favourite until First Brands appear to have screwed things up. The Fleetguard options are excellent, but they are not available for most passenger car applications (though you can check for a cross reference on their site).

Pretty sure it's to show BITOG's different media types. It is informative.

Best bang should be at a Toyota or Lexus site or counter. Online order and pickup oil filters are usually about $5. This is what a Lexus dealer will install.

Based on this statement, you're obviously concerned about the filtering efficiency of the oil filter. The Toyota oil filters are not very efficient, but if you're doing 5K OCIs then filter efficiency isn't as important. Anyway, if you want to explore that more I suggest you go into other threads in this forum as this one shouldn't turn into which oil filter is "best".
 
Positioned mainly for fuel filters right? Congratulations on evolving to further enhanced filter tech.
The really interesting thing about this new media manufacturing process is that we own 100% of the rights to it, meaning we are NOT hamstrung by how we are able to use it either. Most likely it will initially be used in fuel filters, like you said, but that's more of a result of there still being a pressing need for BETTER when it comes to fuel system protection and longer service life of the filters.

There's a good chance this media will be implemented in other filtration product lines, even outside of engine filtration...pretty neat!

Thanks for the response & explanation.
 
Despite being not being at all rigid, the synthetic medias are incredibly strong. This is a somewhat amusing video from Purolator in promoting the media found in their "BOSS" line of filters:


I assume this is a microfibre, not microglass media.

I have used Mobil1 EP for decades but purchased a BOSS for the first time. Should be on par and maybe better.
I use Mobil1 EP 5W-30 at 7k mile intervals
 
Yeah, totally appreciate that it's a different space. You and Donaldson do make a "premium" FL-1A equivalent filter as well as the FL-820S, the pair of which cover every Ford Windsor, most Modulars and most FCA/Stellantis HEMI engines.

I run the FL-1A equivalent on our boat:

And tried the FL-820S equivalent on our Expedition back when we had it, but the ADBV definitely leaked-down and caused startup noise that I didn't get with other filters, so I stopped using it. Haven't tried it on the HEMI's yet, as I've got a pretty good stash of the synthetic media FRAM filters at this time, but it's been in the back of my mind, as it would be a no brainer if they had the upgraded ADBV's.

How long was the Fleetguard in service in your Expedition when you started hearing startup noise? My thought on nitrile vs silicon is time in use. Commercial fleets, at least the ones I've been a part of, service their vehicles every 15k miles or 90 days regardless of mileage. I'm sure heavy equipment has a similar time based schedule.
Here's the response I got from one of our materials engineers:

"I would agree with the comment that Silicone would probably be a premium to the Nitrile for an anti-drainback valve . Nitrile typically will have around 5 to 8% plasticizer in the compound. Over time in a lube filter, this plasticize will be extracted out of the rubber and make it harder and cause it to shrink, so the functioning of the valve will decrease over time, since it will lose flexibility. Silicone on the other hand does swell a bit with exposure to oil, and will become more flexible and will probably seal in anti-drainback valve. Silicone will be more expensive in cost, so probably why it is more seen in premium products.

My guess is that the design of the valve is key to using Nitrile in an anti-drainback valve. By making the flap in the valve thin enough, it will still maintain some flexibility and if the area of the flap is big enough, the fluid pressure will be enough to cause it to flex and seal, in application."
The nitrile deteriorates over time (the engineer didn't give a specific time), so any fleet replacing these every 90 days has no issue with plasticizer loss. If you're dealing with 100,000 units, the cost gets appreciable.

For passenger non commercial service nitrile would be unacceptable, I saw one comment in another thread where they change their oil every year & filter every two years. Nitrile would not be a good choice in this scenario.

Thanks for starting this thread, hope I added some useful insight.

not on par efficiency wise. all the boss units i’ve seen are 99% >46um. construction wise they’re much better than the Mobil 1. same manufacturer.

Thank you. Decades of using Mobil1 EP filters done me well but I did no studies to prove one is better than another, to be honest.
Changed the oil today and placed a BOSS filter on there.

Don't remember, it was a while back now. Probably a few months? But that's just a WAG.
 
Hi all, I'm hosting another media training on behalf of Atmus Filtration Technologies and the Fleetguard brand next month on Friday, March 21st at 10AM CST. The main difference between this session and the one I did last year is that I have invited one of the media team members to join me as a guest, so it will be more of a conversation covering some questions and topics...think more podcast style than pure presentation.

Please feel free to register to hear more and have an opportunity to ask questions during live Q&A:

I've seen the "skunk works" machine that makes all these prototype media that Kevin and the gang cook up. It's pretty dang cool. Imagine a nanotech cotton candy machine and you're not terrible far off.

It's not just that they have the ability to make amazing media in house, it's that they now have the ability to "tune" media based on combining different kinds for different attributes to add particular margin for particular products where it's needed.

For example, the large industrial products for T4 used a hybrid 3 micron/2 micron Nanonet filter for the 2nd stage of fuel filtration. These filters made incredibly clean, nearly-sterile fuel that allowed our pump and injectors to go 20k+ hours without a pump or injector change at midlife.

The downside to a filter that catches almost everything is that it catches almost everything. We had a particular customer in a particular location in the world complaining about filter plugging. But it was peculiar to their location, nobody else was having the problem.

Because of the amazing media ability they have at Fleetguard/Atmus, they were able to identify the particular fuel contaminant contributing to the premature filter plugging, re-engineer the media to be more than twice as resistant to plugging while still providing the protection the injectors and pump needed to last 20k hours.

As a result, we updated all our fuel filters for the industrial line and gave the customers nearly twice as much life with the same protection using the exact same size filter-- it was media innovation ALONE that allowed the improvement.

I joke with our colleagues that the filter media group in Tennessee is innovating faster than we can test and adopt their innovations. We might need to skip one generation of their improvements just so we can catch up.

Just to calibrate you-- the same size and number of filters that was initially launched for T4 product with a 500hr service life are now being used by some customers for over 2000 hours-- and it's entirely due to media innovation and nothing else!

Hats off to the Fleetguard/Atmus folks-- they are second to none.

I can assure everyone here on bob that @Hohn is not my burner account 😂

Thanks for the kind words about your experience. The team here really does amazing work and there is so much focus on finding better ways to make a filter...it's honestly really difficult to convey it to the average joe looking at filter brands on a shelf.

I find this very ironic since Fleetguard, along with Donaldson, operates and markets itself and their products mostly outside of the consumer automotive aftermarket. Your company may be an OEM for HD equipment filtration and for some automotive joint contract venture. The average joe, even the ones here that turn their own wrenches here has no idea who and what Fleetguard is.

If Atmus Filtration, the parent company has plans to broaden the Fleetguard name brand into other markets, its a pretty good opportunity now since your potential competitors that are in this market only only pumping out seas of trash without regards to quality control commitment to save themselves every penny to meet shortsighted KPI goals.

You guys tout a lot about your in-house media mill and development capacity though the reality is its really limited exposure is only seen in the core market you operate in and not much elsewhere other than us filtration nerds in BITOG and probably engineers that have been exposed to your products to see the benefit.

You're not wrong about this. Outside of people in the trucking and other diesel-related industries, we're kind of an unknown, even though we have existed since the last 1950's. Maybe one day that will change!
