Bypass oil filter systems and low micron filtering

[FlyingTexan]

I'm not debating this. I don't drive but maybe 10k a year in my diesel and about to switch to a Caterpillar filter on it. Maybe that's why this popped us as an advertisement but it worked enough to make me click on it.

They're saying 1 micron filtering. Anyone have any actual experience with bypass systems? Considering you can already keep a clean engine running 25k intervals on Amsoil (just read on a guy that hit 1million miles going 25k per change until 500k miles then went to 20k changes) don't really see the value in these products but they seem pretty robustly engineered. Any hot shot guys here that run these things?

Most credible BP systems will filter down to 3 or 4um "absolute". Several of the quality systems (Amsoil, Gulf coast, FS2500, etc) have good data to show they are capable.

Just about any filter can do "1um" ... but very few could do it with any real efficiency. Note that the "insanediesel" webpage makes no claim about how well it can filter at 1um.


Also note that soot particles start out way smaller than 1um; they typically are around 40nm at origin. (That's nano-meters). Meaning they have to grow 100x larger (via amalgamation) just to get to 4um. Particles that small are essentially harmless. Once they get to 5um or above, then they are a concern.

$700 could pay for a few UOA and early oil changes.

No way I'd consider that for 10,000 ODI.

Yea I'm just wondering what the sales pitch is.

Good question. Fading practically with today’s fuel dilution issues - cartridge filters - 20/99 filters - and engine bays stuffed so tightly …

You may want to watch this Flying Texan. I stumbled on it last night as I don't watch this channel.
In the comments I saw Lake Speed thanking the channel for reviewing it so he didn't have to...

Claimed to be more like a Centrifuge system 10x better than a regular filter sometimes called a spinner..

Shows the install and its from 2025.
Not sure if its been updated.

LOL for $700 it should change itself and bring you coffee!

They don't really do anything. Plenty of unhappy customer have done before and after particle counts on their oil using these bypass filters and most have barely seen any improvement.
The reason for that is a decent oil filter can pull all or virtually all the dirt out of the oil that's bigger than about 2 or 3 microns until it clogs.
So no surprise when you put a 4 micron filter on there and the particle count goes down slightly or effectively none.
You're going to have it put a nano particle fuel filter on there or a centrifuge to get a real reduction in particle count.
People who have seen large particle count reductions in their oil using these types of bypass filters are:
Lying.
Accidentally unknowingly contaminated the "before oil sample".
Running a terrible, defective or clogged oil filter.

The Frantz bypass filter is a more economical alternative. After a coupon code mine was less than $300 and for that price I think it is worth it to extend my OCI’s. Over time the savings in oil changes should cover the cost of the system and I plan on keeping my vehicle until it is no longer feasible to fix. Since it is a 2023 4Runner with 43k miles, that is a long time from now.
