View Full Version : Fram vs. Wix: The facts speak for themselves

Billy Zee asked about a Fram oil filter in another post, and I tried to offer him my experience as to why that wasn't such a good choice. I am now going to back up what I said about Fram filters, and hope that certain board members quit behaving like a child, and stop for one minute to take a serious look at this post.

Judge the product, not me.

The basics:
Fram uses a cellulose (paper) media, Wix (NAPA Gold) uses a fiberglass composite. The difference? Cellulose is a natural material with strands of uneven length and shape. The strands can be (and generally are) very close together in some areas (restricting the flow of oil through the media) and very far apart in others (letting large contaminants pass through that should normally be trapped). This is readily noticable through a microscope.

Wix filters use a man-made fiberglass composite media with more "controlled" length and shape to provide more even and consistant spacing, to trap particles down to 25 microns, while not being restrictive to flow.

As far as media quantity goes, more is better, because more media allows more filtering surface, which means less restriction to the flow of oil. The oil has more filtering surface to pass through, and is less restricted for that.

How much more media, you ask? I have on my desk a Fram PH8A Ford filter, and it's Wix counterpart. The pictures I am about to post will clearly show the differences, but the one thing it doesn't show is the "pleat count". I counted the number of pleats on both. Again, more pleats means more surface area, which means better flow and greater filtering area. The Fram filter has 35 pleats, while the Wix has 61. That's damn near twice the amount of media!!!! (Which one would you want on your car so far?)

Here's what the pics show (and a picture is worth a thousand words here!):

Here is a side by side comparison (the Fram is on the left, the Wix on the right)

Notice that there definitely seems to be more pleats on the Wix. Also notice that the spacing of the pleats seems to vary on the Fram, and is more consistant on the Wix.

Here is an end to end comparison:

Notice the paper end cap on the Fram to the metal cap on the Wix. Also, if you look closely, the Wix has a spiraled center tube, which allows greater resistance to collapsing while aiding the flow of oil through the center tube. Fram has a straight seam tube, with circular lines (not spiraled!) through it.

Next, check out the retaining springs at the bottom of the canister:

The Fram on the left uses a cheesey piece of tin, with a very weak thin spring and a plastic clip! The Wix uses a much thicker coiled steel spring (look at the difference in thickness!)

The Fram also uses a rubber anti-drainback valve which is more prone to brittleness than the silicone one in the Wix.

Next, check out the openings at the base of the filter:

The Wix on the left has 6 large openings, the Fram on the right has eight smaller ones.

Last photo, which one would you want on your engine?

The difference in quality is obvious. The difference in price, is about a buck.

I will provide a link to both manufacturers sites, and you are welcome to read further on each.

You can tell me that your engine has lasted a bazillion miles on a Fram. I never said it wouldn't. I only said that Fram was a piece of crap, and now you can see for yourself why. If you have any facts to base a dispute on, I'd be very happy to see them and learn from them.

Wix is not afraid to compare head-to-head with Fram in their advertising. I have yet to ever see Fram compare their product with Wix anywhere!

You don't have to like me, you just have to have a brain. The evidence is right there in front of you.

You can respond with an immature attack on me personally, or you can look at the info here for what it is. I don't really care. I'm just trying to help the other board members make an intelligent choice.

Nobody cares. You're only proving that you're a complete baby and a total loser.

Would you like some cheese with your whine?

Let the members decide if anyone cares. I'm done posting with you, and will be glad to hear other members feelings on the subject.

Three different threads, and all you have done is post attacks and smart @ss sarcastic comments. You have yet to post a single time with anything to back up your claims and dispute mine.

Let the members decide if they're interested in learning anything here.

Yet that's EXACTLY how you started this thread. You even resorted to calling me a "dickhead" in the other topic that will eventually be locked and deleted because of YOU.

Both of you boys know me- and know I love you to death. Now drop the subject and move on.
