interesting, looks like i'll have to give the rp filter a try.
Synthetic FIltering Media/Total Surface Area?

I believe that the openings in the cellulose/paper oil filtering mediums are not all that uniform in size or distribution. Some openings may allow 60 micron particles to pass while others trap much small particles easily, i. e., whatever "nominal" micron size the filter medium is rated for. As the oil is fltered, more of the larger holes are plugged as multiple particles are trapped. (Ever wonder why the oil filter effiency test is rated at a double pass through the media?)
It is my understanding that synthetic media is much more uniform in the size and number of openings than cellulose/paper media, therefore you don't need "twice" as much media to perform the same level of filtering since there are fewer gaps in the filtering medium.

Does anyone know if any studies have been made on the effects of really cold temperatures on the full synthetic media used in oil filters such as the RP? What I would be concerned about in Minnesota, would be whether or not the fiberglass threads would more easily break on a cold start in say an ambient temperature of -20F.
Any thoughts about this?

I saw the Royal Purple Oil Filter on the Champ Labs Website, but I did not see it on the Royal Purple Website.
I called up Royal Purple, and they cannot answer any questions for 1 year, so they gave me Champ Labs phone number which is
1-800-882-0890.
Champ Labs was able to give me part numbers for the 2 vehicles that I was interested in putting the Royal Purple Oil Filters on.
Supposodely since Champ Labs makes the oil filter, they are in an agreemnet that Royal Purple will not answer any questions or post anything on there website for one year.

Yea, so did I. I read a post here that referenced the SYNTEQ media to be 50% at 4 micron but could not find the Donaldson media spec. (Johnny's numbers came from Amsoil so I'll take their word.)
If a PureONE is $7.50 and the RP is $15, I think they would be breakeven economically. I would worry about PureONE loading up on extended OCI but feel the RP class could do x2 the PureONE.
The blend media of the M1, I believe, puts it in the same class as PureONE at least in terms of holding capacity (and probably betas).
Donaldson has several Synteq media for different applications.
This chart shows several of the synteq and others (although not all).

The bypass valve on the filter limits the stress the media will see. Now I do not know the alterations to bypass valve settings in the midst of extreme cold.
Does a spring gain tension when cooled within the range that we're talking about? Now one should not, I think, back spec the notion that when you heat a spring it fatigues ..since you're typically traveling WAY out there in terms of temp. That is, I think you would have to apply cryogenic temps to balance the view. That's not saying that there's no effect, just attempting to limit the range of how deep one is willing to reach in pulling stuff out of one's behind

I went over too Pep Boys and did not see the Royal Purple Oil Filter with the other oil filters, so I asked someone there and they had it on 1 of the endcaps.
I noticed that this oil filter has some sort of a spring at the bottom of the filter inside.

I'm sure all manufacturers do this type of testing. I doubt that we'll get to view the protocol or the results.

I forgot to mention that I picked up 2 of these Royal Purple Oil Filters. I just put 1 on my El Camino when I did an oil change yesterday, so far so good.
I also picked up 1 for my Marauder and I plan on doing a UOA with this oil filter, and then doing another UOA with the Amsoil EaO Oil Filter. This oil filter for my Marauder has a spring at the bottom inside the oil filter.
I still have to do a Rinse Phase on the Marauder so it will be a while.

Look, at the cut away picture on page 4. There is no way it is a M1 clone. It is very similar to a ACDelco Ultraguard Gold that is also made by Champion Labs.
Is this Royal Purple Oil Filter better than the Amsoil EaO Oil Filter. How are both of these oil filters the same and different.
I have never seen a Mobil 1 oil filter cut open but since Champ Labs makes both oil filters I thought they were the same.
Here is a pic of a Mobil 1 and a RP for the same application cut open.

This makes the UPF AC Delco a good buy if you're looking for the superior filtration.
you bet!!!!

I get the same "proprietary information" response from Purolator when I ask them for some simple flow data on their PureOne oil filters.
Seems like if they had good flow, Purolator would want to boast about their performance to make it a selling point. IMO they say it's "proprietary information" when they really don't have any information, as any oil filter manufacture can buy an other manufacture's filters and do their own testing on them.

Probably does not market very well to the average consumer. So instead they put 99.9% efficiency on a box and people go that is pretty much as close to 100% it must be a good filter.

Good point, and a smart marketing department. For the money the Pure One filter is tough to beat, especially for OCI's of 6 months or 7500 miles.
