I collected a bunch of data on 12 oil filters for the 2001-present Duramax platform, and sharing for everyone else that has an interest. This is not meant as a "this is better than that" argument. Just a collection of data, across 12 filters, using money from my own pocket. All of these filters were opened new and unused. I still have all of the filters, so if there's any other measurements someone is interested in I should still be able to collect it.

Wow, that is a fantastic table of information. Thank you!

The wide range of filter media areas is quite surprising. Thanks again.

interesting that Mobile 1 Filter Material is listed as Cellulose, when their advertising lists the filter as SYNTHETIC....any chance the report has a typo or something....also, I didn't see any Hastings or Amsoil filters ????? Thanks for putting in the long and laborious time to compile and publish...much appreciated

All of their marketing material says synthetic blend. Where do you see anything else?

The mobil 1 filter was definitely not a full synthetic. It could have been a hybrid or synthetic blend, it has a slightly darker color compared to the other non-synthetics. I mentioned in the notes I listed the blends as cellulose, mainly because I wasn't sure and didn't go by advertised values for this table. I could always update the table to report the advertised material if that is considered more complete.

Amsoil and other brands weren't purposely excluded, I just decided to stop at 12 filters. These are either all the filters available off the shelf in my area, or are ones I considered using on my truck and purchased online.

Not a shock that the Frams were all tied for thinnest can thickness-usually that's their ONE weakness. Interesting spreadsheet, now to run them all and cut them open to see how they did in real life, along with particle counts... hornets

I'll take sponsors if you want to fund that wink

I do actually have a plan to do basic filter tests against quantitative filter paper, but that's mostly anecdotal and to give me a "visual feel good" about each filter. It'd be in no way comparative to particle counts or testing standards.

What a ton of effort, for nothing. Price, Micron Rating, and Efficiency are the 3 biggest parameters when shopping for any filter and these parameters were not included.

Price is location and vendor dependent. Micron rating and efficiency are usually advertised, and if not requires expensive tests. Not something individuals can do with reasonable accuracy or precision in their home.

Are you saying you truly don't find any worth in knowing the total filter area of the media? Or pleat depth? Or the inlet area between the filter cap and canister walls? Or thickness of the filter media, both relaxed and compressed? If not, a toilet paper filter might interest you.

This spread sheet has nothing of real value..... like if the center tube is punched with holes or louvers. I'm surprized you did not add a line to record the paint color.

Not even something like the country of origin is noted.

You state you still have all the filter parts. You need to revise your spreadsheet.

It's unfortunate you see it that way. What, in your opinion, is worth knowing that can be obtained by a DIY-er at their home, and without an online search?
As mentioned, micron/efficiency ratings are usually advertised, and if not, they need extensive/expensive tests. Country of origin is mostly superficial (IMO), and for the most part found online. The country of origin can change based on the application, even across the same manufacturer and filter. I've seen the CH10246 Fram filter stamped with Made in USA and China, wouldn't surprise me if there was a third or fourth country too.

I assume you just have your preset opinions on what constitutes "good to know". My opinion on "good to know" doesn't involve something that can be found online, advertisements, or discovered by a 2 second glance at the box while at the store.

Good work. One suggestion is on can thickness get a ball for your micrometer or a ball micrometer.

https://www.ebay.com/itm/Mitutoyo-1-Tube-Micrometer/202797605454?_trkparms=aid%3D1110001%26algo%3DSPLICE.SIM%26ao%3D1%26asc%3D40719%26meid%3D75fea78333764e4ab0fc7bf9d78ec902%26pid%3D100752%26rk%3D2%26rkt%3D12%26sd%3D264444866240%26itm%3D202797605454%26pmt%3D0%26noa%3D1%26pg%3D2047675&_trksid=p2047675.c100752.m1982

The .4mm on Fram is too high, it's more in the range of .013-.014 inches. On the standard car filters at least.
One way to get some first hand data on efficiency may be like these guys did. Although if the particle counts are close it may be due to sampling errors. Still it seems feasible to me to run a filter on a diesel to oil change time, do a particle count, leave the oil in, swap the filter for another, run 200 miles, do another particle count.

No clue what you mean, but from what I've seen so far I'm sure things will catch up with you in a short while.
