Where did the 80% @ 10 microns come from for Royal Purple?Credit to @volk06 for the info below:
So Royal Purple is 80% @ 10 microns while the Fram Ultra is only 70% or 74% @ 10 microns depending on which version you get.
Where did the 80% @ 10 microns come from for Royal Purple?
Re: Fram Ultra. While that info has been posted from Fram, prior information suggested 80% at 5 micron.
And based on the post/thread below that seems possible and it beat Royal Purple head to head.
Would you all like to see ISO 4548-12 Oil Filter Lab Testing Comparison, Efficiency & Capacity, Pressure vs Flow, Bubble Point, and Burst?I have this as a “watched” thread, so if you do happen to start a new one, could you put a note or link in this one to direct followers to the new thread? Thanks!! Yes, no problem I can do that.bobistheoilguy.com
...You are aware of that thread as you posted in it...so it seems like you're trolling.
Upon doing a little research on the websites of Royal Purple and Amsoil I noticed that Amsoil has published a 99% @ 20 micron efficiency rating while Royal Purple has published 99% @ 25 microns, 98.7% @ 20 microns, and 80% @ 10 microns.
Fair enough, I can believe they are 80% at 10 micron.Not trolling by any means, how you could come to that conclusion I have no idea. I'll quote the opening line from my original post that started this thread:
Sounds like we should get an EaO tested. I know the RP and AMSOIL look basically identical, but my understanding is that AMSOIL is using the Donaldson Synteq media, no idea what RP is using.Royal Purple looks pretty good per Ascent Filter testing data - it's 96.5% @ 15u so agree it will most likely make the 80% @ 10u claim.
One thing I saw was the Royal Purples holding capacity wasn't as good as I'd expect for being a full synthetic media. And it's flow vs delta-p was the highest in the group of filters tested.
Marketing papers do not tell us tom think that.Use a high quality air filter, Make sure the hoses, sealing surfaces and PCV system is tight and oil filter efficiency becomes less of a concern. The best oil filter is a good air filter.
No, they state: PH8A, 3387A and 4967. That covers large, medium, small i would say.Fram uses smaller filters like 4967, 3387a.
Just to be clear Fram was 99+% in Ascent Filtration's testing at 15micron. Started at 99.9% and went to >99.5% once loaded.In Ascent Filtration's independent testing in 2021 we found out that Royal Purple's filtration efficiency is just marginally less than that of the former wire backed Fram Ultra's media.
I still find it interesting that Royal Purple claims filtration 80% @ 10 microns while the Fram Ultra is 70-74% @ 10 microns. Fram may be better at filtering larger particulate matter but Royal Purple and Amsoil may be better at the smaller stuff.
The only meaningful solution is a bypass filter system. Then is makes a lot less difference as to the exact specs of a full flow filter.Thats right. You can get a super high efficiency filter, but at some point it begins to impede flow. Filters are a balancing act between flow, holding capacity, and efficiency.
No, they state: PH8A, 3387A and 4967. That covers large, medium, small i would say.
Hoss?Those two are small hoss....
So is not like Fram uses ALL big filters for their testing.... That was my point....
They don't use big filters... 2 small and a bigger one.
I suspect the real reason is cost. They use the 99% @ 20 micron media in the ToughGuard already and being a cellulose blend, it's cheaper to manufacture. So, you remove the multiple layers of full synthetic media, you remove the screen required to provide the rigidity, you use your ToughGuard media as the base and then put a synthetic "topper" on it to increase holding capacity and you've just made the can faster and cheaper to produce.So moving from a "baked on screen" will enable them to increase production?
I do not understand, what is the difference here? They bake it on right at the assembly line, and that is too slow?
I think they might have meant "backed" .. not baked. The wire backed media wasn't "baked" on the media. The nylon type screen backing material (not used in the mainstream spin-on Ultras, maybe some cartrridge Frams) might be "baked" on to the media.So moving from a "baked on screen" will enable them to increase production?
