Synthetic FIltering Media/Total Surface Area?

[c3po]

If they are so tight lipped I would just look at buying an oil filter from someone who will talk with you.

I have talked with Champ Labs before, they make oil filters for I don't know how many companies, give them a call, it can't hurt.

The other thing is the synthetic media has more pores for a given size. Less area is taken up by the fiber itself. If the synthetic media has twice (made up) the pores for a given size, why wouldn't it flow better, filter better, and hold more dirt?


I tend to disagree look at the particle count form this M1 VS Amsoil Filter Study:

The only reason why an Amsoil oil filter would not clean as well as a M1 again and again is if the bypass valve is open due to the filter being clogged.

Here are some images of the media:

Sorry, but transferring the data form the microscope to the computer to the editor and then to photo bucket resulted in substantial loss of clarity.

The depth of the element material has to be included in the elements holding ability. A filter element is more than a screen.

That was already covered on page 1. Amsoil is 0.006 less or about 20% than the leader.

guys, this is what i like to know...

how does RP stands when compared to K&N Oil Filter?

Since both are being made by the Champ Labs, both marketed towards performance cars...do we have a reason to believe that they will be different?

 

[Johnny_Law]

The RP is a superior oil filter as it has been disassembled in regards to filtering material and efficiency. Total surface area, filter case thickness, back plate thickness and so on are unknown as far as I know.

How can the surface area of the EaO 20's filtering medium be so small, about one-third that of the OEM filter, and half the size of many other filters... The EaO cans on the Amsoil web site look so big.

The EaO20 has the IDENTICAL dimensional spec's to the WIX 51334


3.194 3.252 20X1.5 MM Attached 2.475 2.173 .233

I really have a hard time believing that there's HALF the media of the same offering from WIX.

When I get some spare chump change, I'll buy both and verify this incredible difference.

Lets say I have 7 by 7 foot square. Now, let me put 3, 1 foot wide boards across that square both ways. That leaves me with 16 holes 1 foot square or 16 square feet of room for air to pass through.

Now, lets say my boards are only 6 inches wide. To get the same 16 square feet worth of holes, I only need a square at 5.5 feet square. Hence, I get the same flow, with a smaller area.

This is essentially the same argument that Amsoil states in that the material used in their filters is thinner, but giving the same or better flow and filter rates than those that use thicker material. Amsoil does not need 7 square feet of filter media ... they can get the same performance with 5.5 square feet of media (for example).

Hence, Amsoil can get away with less material.

At least in theory ...

Edit: My first post ... be nice

After reading over this thread, I have been trying to find the quote from Purolater about how by having so much media packed in their oil filters they maintain both their high filtering effiencies AND proper flow rate. I'll keep looking. A side note; while looking over Purolater's site (under their Classic or regular oil filter), I discovered that they recommend their PureONE for extended OCI's, of 15,000 miles/year! Didn't know that.

If you believe this graph from ACDelco, it shows that the PureOne flows just as good or better than any other filter ... except ACDelco is trying to say thier Ultragard is the best here.
