Oil Filter Testing
 

ran across an oil filer test...https://filtrationcomparisons.weebly.com/index.html

my choice(NAPA Gold/Wix) did very well in the 3 part conclusion. adding a 4th(price) criteria would arguably put it at #1.

NIce find! If you add the yearly NAPA Gold filter sale into the equasion, it gets even better! I buy about 4 filters each year when they go on sale for half price. I get them for a bigger engine, so they're almost twice the size of my OEM one. I pay about $4 each for them.

My own category picks after all these examinations are as follows:

Filtration:
1. Delco UPF 52
2. PureOne, Bosch Premium, and Donaldson
3. Purolator Classic, Mobil 1 Ext Perf. and K&N, Mann, Fram Extended Guard
4. Wix/NAPA Gold and Wix built Delco Duraguard PF53, Mahle
5. Ecore style AC/Delco, Supetech, STP, and Fram Extraguard
6. Denso, Honda, Hamp

Construction:
1. Mobil 1 and K&N
2. Wix/NAPA Gold, Fram Extended Guard, Mann, Mahle
3. Purolator, Bosch Premium and PureOne
4. Denso, Honda, Hamp
5. Ecore style AC/Delco, Supetech, STP
6. Fram Extraguard

Easy oil flow:
1. Denso, Honda, Hamp
2. Mann, Mahle, Purolator Classic, Proline, Fram Extraguard, Fram Toughguard
3. Mobil 1, K&N, Wix/NAPA Gold,
4. PureOne, and Bosch Premium
5. Ecore style AC/Delco, Supetech, STP
6. Delco UPF52 , Fram Extended Guard



it took someone long enough for this to some upon us,

pure one is my choice recently
it's probably good to keep my engine cleaner..
purolator classic seems to be the best all around choice vs cost especially
then look at honda.. and wonder why they get such good mileage...
im not liking the constricted oil flow but thats way better than fram extended guard haha

i don't remember if it was that link, but something i read claimed that some "experts" believe that the filter is more important than the oil! :confused:

what is it that the filter needs to do thats so important? filter better or allow good flow and filter good.. or is it all about the filtering that they were referring too?

That could be true. Major branded oil all meets SAE specs per the labels. (even the store brands do) So then the job a good filter does becomes real important then I would think.

I have been using NAPA GOLD.

Interesting read.

NAPA Gold/Wix man myself. Saves some money over Mobil1 EP filters, but even more so if you aren't going 7,500+ miles between changes. Not knowing the true state of the VX I got just before we hit 2010, I'm sticking to under 4,000 miles every change, even after I got to full-synthetic.

i'd stick to that if i weren't using a TRUE synthetic. remember, the govt allows fake synthetics to be called such if their process(not base oil) is synthetic...https://www.gassavers.org/showthread.php?t=12211

using a true PAO base oil, you need not change it until 10k or more.

I would do that if I knew the driving habits of the previous owner. I'm thinking of using Mobil1 0w-30. I know Valvoline and Pensoil "syntheytics" are all petroleum based still. Do Mobil1 and Amsoil fall under the catagory of fake PAO based or something? Molecular level wise they aren't petroleum based anymore.

Funny, I have a friend that's got his modded Nissan Titan using Royal Purple(he's got a deal on it), but he does a lot of towing. I'd hesitate to put an Ester based oil in a street car otherwise.

ADDED: Might I specify car care of previous owner more importantly.

i believe amsoil and mobile1 both offer non-PAO base oils to attract "budget" minded customers.

a good rule of thumb is to see the recommended change intervals. if they recommend 7.5 to 10k(or more), it's likely that one is a PAO based oil.

i pretty sure mobile1 0w30 is a true synthetic. the difference between that and amsoil's best(also a 0w30), is that amsoil uses a better(more expensive) base stock and adds ester as a seal softener.
