Oil Filter Thread

In the first pic of the inner tube of the FRAM XG2(on the left)in comparison to the Royal Purple 20-820(middle) and FRAM Endurance FE2(on the right)is different where there are holes compared to the louvers on the RP 20-820/FRAM Endurance FE2.

The next three pics are the FRAM XG2, Royal Purple 20-820 and FRAM Endurance FE2.

Imo, the filter media on the FRAM XG2(first pic)doesn't look or feel as quality as the Royal Purple 20-820(third pic with the blue stripe)and the FRAM Endurance FE2(second pic)and can be easily torn. The FRAM XG2 has a cardboard like feel and not a thick soft and cotton feel like the RP 20-820/FRAM Endurance FE2.

All three have a wire mesh backing. The difference being the wire mesh on the FRAM XG2 isn't "attached" to the media where the RP 20-820/FRAM Endurance FE2 are "affixed" to their filter media.

Imo,as for the rest of these three filters in comparison to their outside can(s)all three are hefty and the bypass valves,etc. are similar. There's not anything else insignificant to each other ... maybe the bypass valve setting(s)may be a little different?

Here is an comparison in the first pic of the filter media stretched out. The FRAM XG2(left)is the longest with the FRAM Endurance FE2(right)is a little shorter and the Royal Purple 20-820(center)is the shortest.

Also, pics of the three filter media up close. Second pic: FRAM XG2, third pic: Royal Purple 20-820, fourth pic: FRAM Endurance FE2.

Ok, gotta go and get this stuff picked up before the "Warden" gets back ... she could care less about this ****, lol.

Little tidbit for you,write on a piece of paper which is which if you can.

All of my pics are from left to right/top to bottom starting with FRAM XG2, Royal Purple 20-820,FRAM Endurance FE2.

I believe you guys! I'm just trying to reason out what is going on.

My biggest concern as to why this works is ……if it looses prime when parked…..(parked the pan should be the fullest it can be)

Then it MUST …..MUST! be loosing prime when running as the system is trying to continually be full of oil so the pan therefore has an even lower level.

I'm thinking this, too.

I didn't make clear as to what each of my pics represented. So, I went back and edited them as to what they are.

I didn't take measurements on size/diameter/length, just a visual comparison(s) on the the three oil filters: FRAM XG2, Royal Purple 20-820 and FRAM Endurance FE2.

Fwiw, I'm currently using on my HEMI the AMSOIL AEO11 due to the not so recently unavailability of the Royal Purple 20-820. I'll be using the RP on the next upcoming oci. ... from my memory the AMSOIL AEO11 resembles in appearance to the FRAM Endurance FE2 ... I'll compare those here soon for a look see.

The Fram XG2 has larger holes than the slots of the other two, which also appear more restrictive to flow. But it's a guess which is less flow restrictive without a flow test. Punching small slots is a cheap tool, that I know from manufacturing cost experiences.

Also, the Fram XG2 has wider media than the other two, it has the most filtration surface area. Again, without efficiency and flow restriction test data, we are left to deduce which might be best.

We know an independent lab tested a smaller Fram Ultra XG and a Royal Purple. Both had similar excellent filtration efficiency, and the Fram had demonstrably more contaminant capacity. BUT - the flow restriction for both was not tested in that test series.

A recent YouTube flow restriction test showed Fram Ultra XG being 20% or so more restrictive than a Mobil 1 oil filter, but the test did not include a Royal Purple Oil Filter *sigh*

The inlet holes on the base plate of the FRAM XG2 are actually smaller than the Royal Purple 20-820 but same in number of "holes". I would think the FRAM XG2 would be more restricted in oil flow vs. the RP. I'd like to see a test for the RP as well. The inlets on the RP and FRAM Endurance FE2 are a much better match.

Also, the RP isn't paper thin as compared to the FRAM XG2. It isn't as wide/length but is much thicker and has a cotton smooth feel. I can't rip the filter media with my fingers on the RP or FRAM Endurance FE2, but can tear the media very easily on the FRAM XG2. The FRAM Endurance FE2's media is very similar to the RP 20-820.

From my personal observation the FRAM XG2 media looks to be an blend of filter media ... "duel layer synthetic media" that is brownish/pink in color where the other two filters are bright white in color with obvious woven fibers are present and both state that there is synthetic micro glass media.

I'm still short of getting on and over the fence to try an FRAM oil filter. I'm not knocking anyone who opts to use one for their needs ... I've found an oil strategy that is meeting my concern of being able to keep my HEMI healthy and there isn't any need to "experiment".

I was only really interested in seeing the difference(s) first hand.

The round holes appear much bigger in the picture compared to the slots / slits of the other two, and they're all in the same photo.

I don't understand. I'm not a fanboy of any of them. I'm only interested in science and physics.
Tearing of element doesn't mean much to me, unless it does so during use as the infamous "Tearolators" did. No reports I am aware of with Fram XG.

Thank you for doing this. I am appreciative, only commenting on what I see.

Thanks for doing that JHoward!

Oh and if the 20-820 is hard to get now iv got about 15 left in my basement. They happen to be on sale for $25 each if ya want one

Man, another louvered filter not open enough for good flow. Originally I had thought the louvers were a great idea because it directs the oil up towards the motor but I keep seeing filters like this and I've seen it with my own SRT filters.

Yep, my bad ... I had thought you referred to the "inlet holes" on the base plates, not the inner center tubes ... in reference to the "holes" that are in the inner tube of the FRAM XG2, they are slightly larger than the "slits" on the RP 20-820 and FRAM Endurance FE2.

However, the louvers (slits) do not look like they are restricted on the RP 20-820 and FRAM Endurance FE2 ...

Thanks - it helps to know I'm losing it only in measured increments.
