I use purolator prem plus mostly, but what it comes down to is my local choice for them is pep boys which i really hate. I know wix makes good filters but the gold does not flow as well as the prem plus does, i was curious if the wix/napa silver is a more free flowing filter?
Napa Silver pretty free flowing?

I was told by a Wix rep (for whatever it's worth) that the 51516 size I use (Napa Gold 1516) flows 7-9gpm and filters to 19 micron absolute. I would be surprized if the Purolator PPlus flows much better in the same xref.
One of the freer flowing filters is Fleetguard. You might be able to pick them up at a nearby tractor dealer. I got my last two at a John Deere dealer.
The Fleetguard LF697 flows nearly 16 gpm, whereas the cross ref Purolator L40017 flows about 9 gpm. I am going back to the Purolator, though, because I think the Fleetguard may be too free flowing, that is letting too much through, perhaps.

other filters flowing with very litte restriction along with fleetguard is donaldson and hastings
Maybe Ill just swallow my pride and keep buying the purolators at pepboys. Ive mostly always used purolator air and oil, just wish someone closer had them. Pepboys and napa are like 2 minutes away, everyone else is 20-25. Friggin autozone does not really have anything that interests me which sucks cuz I had to drive over there for my GC.
No Walmart? Discussion on this site (IIRC) seems to indicate that Walmart SuperTech filters are both good and freer flowing.
Also, isn't Purolator "Premium Plus" the more restrictive $5 filter? Whereas the other Purolator (I think PureOne) is $3 or so and less restrictive, probably more typical of a Wix /Napa Gold.

Nix nix. I got it backward. Was at Pep Boys. The PureOne is the expensive one. The Premium Plus is the one to get.
Look at: http://www.oilfilterstudy.com/
This is the answer I got from Purolater. to me 3 GPM is a lot of oil (test probably is done with warm engine. i want a filter to FILTER otherwise why have one. I use pureone
PureOne filters meet the flow requirements of automotive applications. We
test our filters per SAE specification HS806 Chapter 1, and the standard
flow rate requirement that we follow states that the pressure differential
(between inlet and outlet) shall not exceed 3.0 psi at a flow rate of 3.0
gpm. On the PL30001 filters, flow restriction is 0.8 psi (avg) at 3.0 gpm.

NAPA Gold are pretty well known good filters. NAPA Silver ... who ever really knows what is in those cans? Reports are all over the place.

Three GPM isn't neccesarily that much. Although I don't know what most cars come with for oiling systems, the oil pump on my SHO is rated for 12gpm. Not sure what RPM, but I'm sure it's up there
Premuim plus filters are the best flowing for the money. Plus they are top notch in constrction, IMO. I don't like going to PepBoys either, but it's better then supporting a store that only sells Fram.
You may want to try calling around for another source. Mills Fleet Farm carries Purolators for as low as $2.50.

Yeah, i'll just have to handle the 5 minutes im in there everynowandthen for my filters i guess, no biggie.
The Napa Silver filters that I have used were pretty well made for the money. Napa has them on sale for $ 1.99 once in a while. The ones I have used were made by Wix in Gastonia, NC just like the Golds. They seem be about the same as the Gold except they don't have the Silicone ADV and the can might be a little thinner, but they worked good for 3,000 mile dino changes.
The Napa Silver filter for my Honda Accord part #**334 is made in Great Britain while the Napa Gold and the Napa Select are made by Wix in NC. The British made silver filter resembles British made AC's (AC 47) that I used to get for my dads Pontiac. I recall that an article years ago in "Consumer Reports" said that these British made AC's filtered about the same as American made filters but that they had much greater capacity to hold contaminents. Does anybody have any info on who makes these filters in Britain and are they any good? Thanks
The Pep Boys "ProLine", made by Purolator and identical to the Purolator "Premium Plus", except for labeling, is the one to get. ($2.50...
The media is exactly the same? The motorcraft was supposed to be the same as the Pure One, but tests show otherwise.quote:

Interesting. Maybe better than a SuperTech. Although currently there is a Purolator 2 for $5 at Pep Boys. Still, the Motorcraft may be best since it has the bypass on the threaded end.quote:

I have looked over the oil filter study TallPaul has posted here a few other times, and i just don't see how you can beat the Purulator Prem. Plus when it comes down to filtration and flow. At the price I can buy Purolators for in comparisson to Wix/NAPA around my home, the answer for me is easy, usually at least $2-$3 cheaper for what looks to me to be a better all around filter, especially when I use conventional oil and change by 4K miles.
