It can be beaten to death over and over again until hell freezes over. Just change a few words in the title and it will take on a new life. Just look at thick vs. thin, thin vs. thick, UOA and engine wear, UCL, MoS2, Ceratec, MMO, etc. to name a few. This just started for the"new" Fram Ultra filters.

The new one has depth filtration. All these oil filters do, some have more like the Old Ultra had more. It didnt have depth like a Baldwin old depth filter or others. Fram had a Filcron depth combined element in 1942. None of them are plain screens with one layer of mesh like a window screen. They all filter through some depth. 645 already.

my recent ebay purchase of the mismarked screenless ultras was quickly refunded and returned via USPS, I have about a years supply of screened left for this mess to get figured out...I like to MityVac OCI so need a 20-25k service on the GX that way I don't have to remove the skids, T4R filter is topside so goes quick...Hope another mfg. will fill the market void @ close to $9ea.
Gotta match 'em up for max performance ... thick oil with thick media, and thin oil with thin media.Which is better, thin or thick media

It's still pore block. Cellulose doesn't provide much in the way of depth filtration, I've posted documentation from Fleetguard on this previously, most of the filtration happens on the surface of the media (hence pore block). A synthetic glass or fibre media, like the old ultra, provides true depth filtration, which is why it has the holding capacity it does. This also means the media isn't rigid, which is why it required a screen backer.
BTW, you should really use the quote function, it helps people know when you've replied to their post.

From Donaldson:
That's the point of the synthetic depth filtration media: Better holding capacity at a given efficiency rating, and better flow. It just does everything better than cellulose or cellulose blend media.

Digging through some of my old oil filter info, I had this from Purolator emails back when the PureOne was the rage.
@5u - 51.3% efficient
@10u - 92.8% efficient
@15u - 99.2% efficient
@20u - 99.9% efficient
@25u - 100% efficient
@30u - 100% efficient
@40u - 100% efficient
If you plotted that curve, it looks to fall-off pretty fast below 15u. This may be the difference between a good full synthetic vs a cellulose or blend.

Yes, and as you make cellulose more efficient, it loads up quicker and becomes more restrictive as well because it lacks the depth that a true synthetic media has. We went over this with Farnsworth back in 2019 in a previous thread. Then you need to increase pleat count and surface area to try and counteract that.
LOL I'll wait for the dissections. Until then no comment........... Maybe.Which is better, thin or thick media
It is just simply a plane of holes, like a window screen, or it isn't. Even if it looks thin, all fiber oil filters have depth filtration. That's all I am saying. A cellulose fiber has extra depth filtering in each fiber, which is why I like cellulose or blended filters. It's like having little micro filtration in each fiber. The fatter they are the better.
Yes, I know it went down hill since they had new design. Still does not look too bad. I am having hard time deciding on a filter with best quality for $10 budget.
In theory if your doing 5,000 oil changes you could go 3 oil changes on the same filter if you wanted to. Tough Guards are rated by Fram for 15,000 miles of protection, but many on this forum have run them longer.
This makes 100% sense, but let's apply that logic to the new filter. Don't you think the new filter material is strong enough to handle 20k miles or Fram wouldn't have made this cost saving change?
Can any confirm the actual filter material on the new ones is the same as the old ones, or is it different... maybe a little stouter?
Do we have anyone who is approaching 20k miles on the filter that can cut it open and take a look?

Thank You sir Overkill for the info. I always learn stuff from your posts and knowledge
