NAPA Gold or Fram Ultra?

[Blagoje]

After reading the original question, "Fram Ultra or Napa Gold?" and all the subsequent comments, I think the answer is "yes."

Two great filters that will give you many many miles of worry-free performance.

I am not sure at this point what the OP was intending to accomplish based on their responses throughout this thread. It is kinda been going nowhere

When you call Wix on the telephone you aren't talking to someone who necessarily knows what you are talking about. An out for not knowing can be to say "it's proprietary." An engineer isn't waiting by the telephone as a call answer person. They probably have an admin assistant doing it. They answer questions like what oil filter is for my 89 Cadillac, and they look it up on the website while they are talking..

The people on the phone are trained Customer Tech Support - they better know what they are talking about. WIX and the techs on the phone know the efficiency ... they are not going to tell anyone because they've been told to tell people asking about efficiency on that particular filter that it's "proprietary" for a reason ... not because it's a lame excuse for supposedly unknowledgeable people working the phones.

Any filter manufacturer who gives you the answer of "it's proprietary" is trying to hide something. Letting your customers know the efficiency is basically the most important piece of information you should have to help sell a filter ... unless it's so embarrassing compared to the completion that they don't want people to really know so they go down the "it's proprietary" path.

In the real world they, the office staff, most likely tell you it's proprietary because they have no idea what this efficiency is you are talking about and there are other callers on hold. That's proprietary information sir. Next!

Don't forget that at one time WIX published the beta ratio (efficiency) specs on the XP on thier website. Around that time I and a few others here also called WIX Customer/Tech line and was told the XP efficiency was 50% @ 20u. Now it's "propriatary". Doesn't take much critical thinking to see what happened with the efficiency info.

The word efficiency is being stated quite a bit in this thread. The definition of efficiency is explained in several different ways from the results of a google search. I'm trying to grasp the correlation to the performance of an oil filter. Is it how much the bypass valve comes into play? Is it how small the particles are that are filtered out? Is it how much volume of undesirables are captured in the media before the amount of oil being delivered to the engine components is insufficient to deter wear? Something else? I don't claim to be some kind of guru of the science of oil filtration so I guess I need some enlightenment here guys.

Well you seem to respond to a genuine effort to enlighten you with "whatever".

But here goes: Efficiency related to an oil filter is how effectively it removes particles of a given size most commonly this is stated as the results of ISO 4548-12 at a given size and percent: For instance: 98%@20 microns.

The other way efficiency is sometimes stated is "nominal" which generally means particle size at 50%. So a 5 micron "nominal filter" is ~50% efficient at removing particles 5 microns in size.

So efficiency equals catching particles.

A filter that is 98% @ 20 microns is a much more effective filter than one that is 50% @ 20 microns or 20 Micron Nominal

An efficiency rating that doesn't state how it was obtained is not useful.

This is probably overly simplified but it should head you in the right direction.

^^^ To add to the above, every oil filter will exhibit an "efficiency vs particle size" curve. Example below.
