#2540747 - 02/18/12 03:05 PM Microgard versus STP-- Cut Open (Ford 4.6/5.4)

Gang,

As promised, I have cut open one each of the O'Reilly Microgard and one of the Autozone STP filters. I have also opened the MC FL-820s from my last OC (7,480 miles); which you can see the details here Motorcraft FL-820s.

I did not pull the media apart and measure it and my post is merely to show the visual differences between the filters and hopefully to give people some information from which to make an informed decision regarding the use of them. I did try to place a tape measure in the photos to show a reference point when I could.

I also did not post any of the cans, but I am able to say the Motorcraft had the thickest metal, followed by STP, and then the Microgard. A Summit Racing Filter Cutter was used to cut all filters and it took less than 45 seconds for each of them. Very nice cutter for the price!

I am posting some group pictures, followed by the Microgard, and finally the STP. Apologies for the images that are sideways (not sure why ImageShack does this).

Enjoy!

I'd take the microgard between these two, but only for short intervals. Approaching 5,000 or more is risque. No thanks. smile

The Motorcraft is the best by far.

Between the STP (ecore) and the Microguard (FRAM), I guess I prefer the Microguard. I just feel there is less to go wrong with that design.

I'd take the used Motorcraft over a new STP or Microguard.


Thanks for the pictures--I would send em off to E-Bay as you previously suggested

I had never been tempted to try either of these brands but your pics will forever prevent my reaching to that part of the shelf. Just highlights what true value is in the MC FL820s filters. If only they would add a premium media, life would be perfect.

The STP's dome-end plate only holds the filter element in place. The actual bypass "valve" is built into the ADBV.

Known as the "Combination ADBV/Bypass Valve" ... which a lot of people don't like.

Correct; I was copying and pasting and meant to edit that for the STP filter.

Thanks Jim; trying to do my part to increase the knowledge pool here at BITOG.

I did not really post an opinion, but since there has been ample time for all to comment, I will say that I would not use these filters even for a short run, I feel the quality is really poor in both of them.

On my FX4, the Microgard would be into the lower radiator hose a little (it is longer than the MC) and would require me to use two hands to install it--1 to hold the filter and 1 to move the hose.

We also have to keep in mind both of these filters are $3.59 at AZ and OR in my neck of the woods (when not on sale or in a special) and MCs are only $3.99 at both. IMHO $0.40 is hardly worth me worrying about to quality of the filter and the FL-820s is proven--tried and true.

I plan to exchange or eBay them, they will not be installed on my truck.

Amen, brutha! If you hadn't had to buy them, and of course you wish to recoup the expense, they would make good targets.

Oh, by the way, stretch out on the couch there and explain to us what motivated an apparently rational BITOGer, and otherwise sensible man to buy a krapload of inferior filters? Hmmm, to vee haf some hidden issues here? ( : < )
