by-pass oil filter?

[aznatama]

Has anyone experimented with bypass oil filters? Synthetics hardly break down, and we only change oil due to contaminants, so the theory is that the bypass filter element will filter out much smaller particles, thus allowing a longer service life for the oil.

This makes sense, if you run a good full-flow filter, one the pores get clogged up, it'll only filter out the larger particles while the smaller particles are sent through the bypass valve. This is where the by-pass filter come in, filtering a smaller % of the oil, but filtering down to 2 microns (normal filters filter down only to ~20 micron when new). The only concern is the effect on oil pressure.

Any thought?

My thoughts are unless you're running at redline in a perpetual duststorm for miles on end, the standard oil filter is fine and you won't need to worry about anything.

The manufacture says to change the oil and filter every ~6k miles for a reason.

But what do I know? At the end of the day, I'm just a guy on the internet.

Bypass oil filter won't affect oil pressure at all (hence it's "bypass" name).


It's a bit of overkill, but it certainly won't hurt anything.
