Oil Filter Tests by river_rat on BITOG Forums

I tried to consolidate all the tests, that thread was about 33 pages long

I got them cut open last night, The Donaldson, PureOne PL30001, and Motorcraft FL-1A--all new and unabused.

Notes:
1. The Donaldson has what looks like a Purolator style bypass valve.

2. I didn't measure canister thicknesses as they all seemed about the same.

3. Only the Motorcraft had the bypass on the threaded end. The others were on the dome end.

Approximate medias are as follows:

Donaldson = 207 sq in surface area, 8.3 cu in total, .040 in thick. Fine texture, white, appears full synthethic and has a screen backing.

Motorcraft = 242 sq in surface area, 6.5 cu in total, .027 in thick.
Relatively course texture celluose or cellulose/synthetic blend by appearance.

PureOne = 310 sq in surface area, 7.1 cu in total, .023 in thick.
Fine texture cellulose/synthetic blend by appearance.










First test: L to R; Donaldson, Motorcraft, PureOne


Third test: (note L to R order change): Motorcraft, Donaldson, PureOne
Since these are not as sideways as the other, you have to look cloesly to see all the grit that is sloped up to the back--away from the camera lens. Still, the rankings are the same in my book.
