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.
