WIX XP cut open ...

Looks like a decent filter.. I didn't catch what the efficiency is on this one? I enjoy this guy's demeanor.

Looks like 88%@35 microns... lousy for me but if you're doing like crazy long 15k+ intervals this could work.
It’s still under 90% @ 55 microns… that’s nearly unheard of (in a very BAD way). That means 1 of every 10 particles that are .0022” will pass through the XP media, headed on its way to the main bearings, which are usually set between .0020-.0025”, with rod and cam clearances even tighter. What happens when you shove a solid particle into someplace that’s bigger than the clearance? Scored & damaged bearings. No thanks, tried them a couple times before I saw the efficiency graph, won’t ever use another one as an engine oil filter.
 
Can anyone please explain why the efficiency is better in Regular wix than the wix xp?

Just because of different designed media that is more efficient. The XP is supposedly designed for long OCIs, but so it the Ultra and it's efficiency is very high. Goes to show that if an oil filter is designed well, it can be high efficiency, low delta-p vs flow and high holding capacity.
 
Or 62% @ 20 microns.


Not really, because oil filters get less efficient as they load up with debris. That is also discussed in the long Ascent ISO testing thread.
I was intending for it to state similar to what you said but with my lousy wording.

"The XP is supposedly designed for long OCIs"

It's similar to a conversation I had with Purolator when they first came out with the boss fillter. It was designed for long drain intervals without clogging up. The guy was talking about Mercedes teaming up with them on these filters for long 15k drains & they didn't want any clogging to happen. We all act as if a filter can never get clogged. Ever been to a gas station that pumps so slow? Clogged filter lol

We both agree that the boss's initial 99@40 microns, & the wix posted here, are really lousy compared to say the Fram Tough Guard or Ultra.

Interesting side note: for the 6.0 powerstroke they only make the TG since it's a big filter with great efficiency. I suppose they decided it was more cost effective not to offer an ultra for this engine. I can get a boss though. Some people in my situation may opt for this xp or boss. slim chance but possible.

Yes, very lousy indeed. There are better specs on other filter brands. Unfortunately, wix sells a ton of these filters. Not sure if it's hurting their bottom dollar very much.

I see what you mean now, and seems that you don't care about the efficiency as much as the miles ran on the filter. How long of an OCI are you planning?

Of course oil filters can get clogged, but it would have to take a pretty dirty running engine to clog up a filter rated for 15K or 20K miles.

I've stated that the efficiency was pretty lousy several times. I care very much about efficiency. That's why I run a TG or Pure One on my truck. I'm stating Their position mainly.

Based on my conversation with Purolator THEY were worried about clogging. However, the oil filter manufacturers do a decent job of PREVENTING that from happening. Can an oil filter get plugged... Absolutely.

I try not to be in any one crowd. Longer drains vs shorter drains. They both can work well. That being said for me I want excellent filter efficiencies in both of those situations. So 99@20 is where I stand.

I plan on running an annual oil change on my 6.0L Powerstroke. I suspect I'll be anywhere from 8500 to 10500 miles on the oil. Using the TG or P1 filter "Rated at 10k miles". I've scored about 4 Oil analysis kits for cheap so you'll see my post in the UOA. I've owned the truck for only 3 years & have never gone that long before but I'm planning too.

Have a great day... It's Friday :)

What you're doing with the TG or PureOne is already working for your OCIs, and meet the efficiency target. If you want more loading headroom, then go with the Ultra since it's rated for 20K miles of loading.

Right

There is no Fram Ultra oil filter for the 6.0L Power stroke. As in they don't make one. I would go with a Amsoil filter if I wanted to go further than 10k but I have no plans, for now, to run that long on this egr equipped diesel.
