Oil Filter Upgrade, Bigger one for the 5sfe motors (UPDATE) Options

[Bigmeanbulldog55]

I don't know about everyone else, but I hate it everytime I go to change my oil and am reminded of how small my oil filter is. How can that thing do the job that the 2.2lt requires? So, I found one that matched the thread pattern and diamater and just put it on my car. It's a PureONE PL14477. It's only about a half and inch longer, but it's enough to make me happy. I'll try to find out what car comes with that.

EDIT: Update at bottem.

Filter Size and Life Cycle

Oversize it?

Lets take a look at the life cycle of a normal oil filter. A filter works best, with both effective flow and cleaning some time during the middle of its life. At the beginning it is a little too "open" to filter out the smallest particles. But because it is open it flows well so resistance to flow is minimal and flow capacity is very good it is just that the ability to filter out the smallest talc sized dirt is not very good.



During the mid-life period as the filter collects soot, metal and carbon the pores of the filter media trap and plug the tiny spaces with in the fabric. As a result the filter becomes less permeable, it flows just a little less oil for the same pressure and temperature, but it does a better job of filtering out the very fine sub 20-micron particles that cause the most wear. The filter is in the sweet spot. SPF and, capacity are both acceptable.

Toward the end of a filters life the dirt load that is filling the pores is choking off the flow capacity. Anything getting through the media is clean but the quantity of clean oil is not sufficient for the engines needs. We risk starving the bearings for oil, or the bypass will always be open, and in effect we are doing little or no filtering at all.

So the dirt carrying capacity or shell size is related to engine size in a rough sort of way. The bigger the motor the more wear surfaces, the more dirt inhaled so during the same 3000 mile oil change interval it will generate and need to trap more dirt. If we take an oil filter typically used on small block V8's or even big block engines they have twice the filter media area as the smaller filters. When time comes to change the oil at 3000-5000 miles they may just be getting in to their most effective part of their life cycle. Hence they never function optimally, or spent far less time in that range where small particle filtering is most effective.

I think that data applies more to paper than synthetic filters. Pure One uses synthetic media.
I think if there is no significant loss in oil pressure with a larger filter than there would be a slight advantage with more filter surface area.
