joe, great idea. i'd be willing to make a financial donation of a few bucks-i'm sure other members would as well. can do it first rate that way and everyone could get involved to make as good as possible ive got a nice digital but don't know the least about posting pix (see my prior threads-someone had to help and it still took a couple tries) or websites.
Again,Great Idea.
Again,Great Idea.
Dunno if this is any help or not: I have several used oil filters awaiting surgery(a good thing). I have no digital camera or scanner(a bad thing) I could, when I finally cut 'em apart, take photographs of them, & mail them in. Might be best to just use new filters, but remember there will almost certainly be variations between models made by the same company- could get very $$.
joee12, so i assume your gonna be using honda filters for this study? ill donate some filter if need be.
I agree totally. PayPal doesn't work for me (long, off-topic story) so tell me how I can help. I have a scanner, but then again live in Canada...

I would definitely donate money through Paypal! I donated $18.50 to the LS1 long term oil analysis test to pay for one analysis for example. Anytime someone does a study that benefits everyone, I have no problem chipping in a few bucks. Just be sure to put my money towards buying some K&N and Wix filters!

Wow that was quick, I went shopping with my wife and daughter for a few hours, and when I come back, I already have six members willing to help.
Rick, thank you for the offer to put the page together, this was the part of the project that I needed most of the help with. I could easily email the pictures and the text to you.
Stuart, I am going to suck it up and purchase brand new filters, thanks anyway for the offer on the used filters. Here is preliminary list of filter brands I was thinking of:
Motorcraft
Purolater Premium Plus
Purolater Pure One
Mobil 1
K&N
Bosch
STP
Supertech
Fram Extra Guard
Fram Tough Guard
Fram X2
AC Delco
Wix
Napa Gold
Napa Silver
Amsoil
Baldwin
Mann
Quick Lube Filters
-Mighty
-Jiffy Lube
-Valvoline
Any other suggestions, let me know!!
Oilcanboyd, I was actually thinking about another filter, like the equivalent of the Motorcraft FL820S. The Honda was pretty well covered in the NTPOG study. Thanks for the offer on the donation of a filter, I will probably take you up on it.
Smeltjr/Rob-the-oil-nut, thanks for your offers, I may also take you up on them depending how expensive this gets.
Patman, how could I not do a study on our favorite filter, the K&N. I gotta tell you though, I just cut open a K&N to send Jason Troxell the media for him to analyze, that was a bear. Thank you also for your offer.
This thing may take me a while, but I have meaning to do one for a quite some time. I plan on starting this week and rounding up all of the filters I can get locally. Thanks again for everyone's support, Joe

What a list!
You might find a Hastings filter easier to find than a Baldwin...use either one, they're identical.
You might look for a NAPA/Silver filter that's visibly different from the Gold. I've heard that some Silvers look OK (the one I cut open) and other models of Silvers look really junky...look for an imported Silver, not a U.S. made one.
To which model car are you matching these filters? If it's one that takes a bypass setting of more than 8 psid, it would be interesting to see which filter makers spec the 8 psid bypass valve, presumably as a way to reduce their inventory requirements.
Maybe light-test the bypass valves...shine a light on one side and look at the other for openings.
Can the antidrainback valve be tested? Fill the filter with a very light oil (kerosene/oil mix?...about the same viscosity as hot engine oil?), invert the filter, and see if it leaks?
Any room in your survey for OEM Japanese filters?
Anyway, big job ahead of you.

is there any way you can try a FILTERKING oil filter? their sooo cheap and i wonder whats inside.
http://www.filterking.com/oil.htm
ill give ya some money if you try a filterking brand filter. im curious as to what lays inside.

I have digital pictures of a Motorcraft FL-820S and a Purolator Pure One PL24651. I cut them apart a while back to look at the insides for myself. I can e-mail them to you if you like.
Guys, I have an idea to conduct an oil filter study, and Ed P has been gracious enough to host it for us. It seems like we are always providing each other with links to various oil filter studies, some of which are outdated. I think that it would be great to have our own oil filter study right here on Bobistheoilguy.com for members to refer to. I am looking for people who want to help. I do not have a good digital camera, and know nothing about developing a web page. I am willing to pay for everything, filters, shipping costs, materials, etc. If anyone is willing to help, please let me know. Thanks, Joe
I've got a few of the FL-820s equivalents cut up already. If needed I can get a dig camera to take a few pics. I have the following:
Motorcraft FL-820s
Purolator Premium Plus
Purolator Pure One
Quaker State (Same as Purolator Premimum Plus)
Fram Extra Guard
Fram Double Guard
Fram Tough Guard
Fram X2
Casite (Hastings/Balwin cheap line filter)
Obviously I'm interested in the FL-820s equivalants too!

When you get settle on what application (ie part #) you want to study let me know. I'll shoot you the Amsoil filter.
Almost forgot: No charge, of course.

This study is great however, we are forgetting the real issue in examining the construction of these filters. The assumption is that better construction or filter media etc. results in lower wear.
The real question is to test each filter in the same engine same interval same oil with analysis to see which performs better. My hypothesis is that it will not make any difference in wear on an engine as to which filter you use. Bob has indicated that is some of his last posts about the Fram he was using. Especially if you change oil every 3000 miles. Maybe, just maybe at 10,000 miles it may make a diff but I doubt it also.
This study will not help to decide if we are wating money buyoing K&Ns, Pure Ones, Amsoil etc. when an el cheapo Fram will do the same trick!

I disagree. A filter that is very restrictive to flow, that is used on a car that is driven fairly agressively, will show more wear. Bob proved that with the Mobil 1 on his car. The theory behind that is that the restrictive filter disrupts the flow when it's kicking in and out of bypass mode. During this time, the engine sees more wear because it's supply of oil is restricted so much.
So if you have a filter that doesn't bypass as much, it will show lower wear.
I do believe Bob would see even lower wear numbers if he ran a K&N or Wix filter.
there is also a brand of quick lube filters called "service champ"... i have a used one sitting in an oil pan if you would like it... i could clean it pretty good...
also test out castrol/penske from wal mart...i could send you a honda OEM filter straight from the quik lube where i work (part honda dealership)

Also keep in mind that AC filters are made by 2 companies, Delphi and Champion, I used to see the Delphi at Kmart, and the Champion at Walmart. The local Chevy dealer used a Champion version of the filter after they made a repair on my motor. They both had the same sqare inches, but the Delphi had fewer deaper pleats, and the Champion had more uniform (and more count) shallower pleats.
for which car do you plan to study opil filters? and also after looking at your list you left out the pennzoil, defense, proline oil filters.

Pennzoil filters are Fram, Prolines are Purolator, and Defence are Fram, so he didn't leave them out. They are exact clones.
