The photos can help somewhat with construction quality. Hey take a look at the photos at this thread. The Supertech filter dosen't look very good on basis of quantity of filter media:

As for me, I am going to stick with Motorcraft and the longer Purolator with the bypass where it should be--in the threaded end. I think Wix is good that way too--at least the longer one is.

 

Oppy, our opinions sure are different!!!!

In this case, the construction analysis of the filter tells a lot about the quality of the filter. The type of filter media, and how much of it, is a great way to compare the filtering ability of different filters!!

 

At last, something we can agree upon!!

 

NAPA Gold or Wix, either one will do me. Both by Dana.

 

while looking at one of the cut open filter sites the motorcraft is the same as the higher priced pure one filter
the visual quality is among the best

 

I like the Purolator PureOne, but the SuperTech seems almost as good. The Purolator PureOne has 99.7% SPE and 98% MPE while the SuperTech has 98% SPE and 99% MPE. Also it is made by Champion Labs and closely resembles ACDelco and Champ filters. It's for sure better than the dreaded FRAM's. Anyway what are your opinions on the Wally World brand?

 

i think motorcraft is a great filter. i use super tech made by champion as is the bocsh they look the same. cant beat that price just stay away from the orange turds!!!
best thing is change every 3000

 

After reading all these posts, the only thing that stands out to me is everyone can repeat the standard manufacture's jargon on command. I have not seen any posts that tell me what particle level these filters are accurate to (how many microns). I have seen one filter that tells me specifically that it filters out particles down to 10 microns. All others seem to talk in generalities and percentages. I want scientific facts. Can anyone tell me what their particular filter's filtration level is?????? How many microns??

I think the problem is we cannot find good information either, so we go on what we have.

 

Pure One oil filters have (slightly) the best filtering media. They're essentially perfect at 30 microns (99.7% multi-pass), and very effective at 20 microns. The Pure-One is reasonably effective at 10-15 microns, picking up in the 80% range or so.

Champion makes the Mobil-1, Bosch, and Supertech filters. The Mobil-1 has the best media, with filtering characteristics almost as good as the pure-One. At double the price. The Bosch and Supertech filters are a step down from this, and are not really very effective at all below 20 microns.

Wix and Hasting both know how to make excellent filters, however I have been completely unable to find out which of their filters have their improved filtering media. The Napa Gold line, which is made by Wix, is comparible to the Pure-One in some part numbers, to the Bosch in others, and to normal 35 micron filters in yet others. Wix won't tell me which is which. The Hastings filters have excellent media, but the filters I have disassembled don't have much of it.

I've worked on this problem with Jon Sutterfield, who is a filtering engineer in the food processing industry. It's true it's difficult to get meaningful filtering numbers on oil filters. However, I think it's clear that there's no better filter than the Pure-One.

Mark,

In your best opinion, what type and/or viscocity motor oil should I use in my automobile. I live in Minnesota, where it occasionally gets to -45F.
Thanks for your opinion.

 

pawpaw ran across this data about a year ago whle researching filter construction & efficiencies.

Be mindful it's somewhat dated, but nonetheless interesting.

It gives micronic filtering efficiencies vs time, for several popular brands.

Also gives time until the filter clogs & goes into bypass.

Enjoy the info.

Just curious - why do you refer to yourself in the third person? oppy wants to know!

Interesting article.

 

Oppy: for the record, "Scenic Wisconsin" is redundant.
