Oil Filter?

[Bo Tie 1]

[Russell James]

Out of curiosity, cut open a PF48 tonight out of my Walmart stash. I've noticed they changed the name recently from Duraguard to Professional. I just wanted to make sure none of the guts changed. Looks to be the same as they've been for years. Metal end caps, metal core, rubber anti drain-back valve, coil spring by pass valve, 60 pleats, made in the USA. Pretty decent filter for $3.68 at Wallyworld.

I'd say, there are definately worse out there, and better if you go to a premium filter. But there isn't anything this one is going to do wrong, it's got all the basics. Hopefully this part number never goes to the ecore. You can tell those by the E on the end like a PF47E.

Awesome Russell James, thanks for doing that.

I second that.

Wix #57060 or Napa #47060

The NAPA filter has the new synthetic media for better filtration and moisture resistance. The Wix is your standard wire mesh paper media.

An earlier thread here on Camaro5 mentioned ACDelco's own UPF48R Ultraguard filter. I bought a batch on Amazon.

Anyone ever cut one of these open to see what's going on inside of it?

The UPF48R has a thicker exterior shell and can also be identified as GM part number 12626224. It was designed solely for the purpose of withstanding the higher volume and pressure of the LS9 oil system. The internal components of the UPF48R and the PF48 are identical. The UPF48R can be used in applications where the PF48 is specified, but the only thing you gain is a lighter wallet.

Just ordered one of the Amsoil filters to try out. Also making the switch to them for oil this weekend. Got the 100% synthetic 10-30.

Do they really make filters for Mobil 1.

Amsoil yes, but why 10-30?

Ted at JRE recommended the 10-30 since I have a single turbo on an SS.

If someone has a UPF48R laying around you could probably just look at a few things and tell if the guts are the same. One key to premium guts is the anti-drainback rubber valve material. On premium filters that rubber piece is often orange in color, a different rubber material that supposedly is better. You can see it through the small holes outside of the larger center hole.

If you see black rubber under those small holes, like the circular valve in my pic, i'd bet the guts are the same. When the UPF48R came out, they said it was just a thicker cannister. But if it has an orange valve, I'd suspect more differences like premium media.

No. Champion Labs makes the Mobil 1 and AC Delco oil filters. They are not the same filter. Each manufacturer has Champion Labs build the filter to their specs.

Champion Labs also makes filters for but not limited to... K&N, Royal Purple, Bosch, Deutsch, STP, Super Tech, Motorcraft, Valvoline, AutoZone, Lee, Valvoline, Quaker State, Shell, and some Mopar.

Silicone and Nitrile are the most common materials used for ADBV's (Anti-drain back valves). Silicone is definitely the better of the two because it stays a lot more pliable in sub freezing temps than Nitrile. The color of the ADBV means nothing because that is not an indicator of what it is made of. Silicone gaskets, seals and o-rings can come in many different colors. The most common types of colors are black, orange, red, green, brown, gray, blue, yellow and transparent.

The L99 and LS3 don't need an ADBV and it serves no purpose since the filter is mounted vertically up. IMO, if the ADBV wasn't there the flow might actually improve a tad.

In 2008 there was 6 oil filter manufacturers in the US. I don't know how accurate this holds true now but this is how it was then.

- Baldwin/Hastings (Makes Baldwin, Hastings, and Amsoil filters)

- Champion Labs (Makes Car and Driver, Champ, Deutsch, AC Delco, STP, K&N, Royal Purple, Mopar, and Mobil 1)

- Dana/WIX (Makes Carquest, NAPA, WIX, Castrol, and Penske)

- Donaldson (Made Donaldson filters. Not sure if they are still in business)

- Honeywell (Makes All Fram filters, Pennzoil, and Quaker State)

- Purolator (Makes Bosch, Motorcraft, PowerFlo, ProLine, and Purolator)

Pretty accurate. I know Motorcraft and AC Delco outsource to more than just one company. The PF48 and UPF48R are made by Champion Labs along with other AC Delco filters but not all of them.

Amsoil makes their own EaO filters. Donaldson holds the patent for the filtering media which is called SynTeq. Amsoil holds a licensing agreement with Donaldson to make the filtering media themselves and calls it NanoFiber.

Donaldson is still very well in business. IMO they make the best oil filters (Endurance series) and one of the best air filters (PowerCore series). The only problem is they make very few filters for cars. Their business practice is oriented to pickups, semi's and heavy equipment.

The valve helps keep the engine's oil circuit from draining back, not just draining from from the filter. I've worked on several V8s with vertical filters with a complaint of start up lifter rattle. Changed the filter to an ACDelco, and it solved the problem. Often an el cheapo quickie lube filter to blame.
GM has had a few bulletins over the years to check for an aftermarket filter with a bad of missing valve.

If the filter is mounted up high, like an Ecotec 4 banger, then those don't need an anti-drainback valve. But anything with a low mount filter should have the valve to keep the oil system primed for cold start up.

You can tell a valve isn't sealing or missing by when you take the filter off, on a low filter a lot of oil should come out as soon as you break the seal loose. If nothing comes out, the valve isn't holding oil up in the motor.

Thanks for the correction. I honestly never took all of that into consideration. Even though the filter is mounted vertically up, being so low on the engine what you are saying only makes sense. On my Cummins the filter is mounted higher up on the engine. It is just below the height of the head and there is no ADBV on the filters. I always prefill my filters thru the inlet holes and not down the center.

To each his own on opinions.
Tests don't lie
Haven't bought an Oil Filter for my truck in 8 years.

[Silverlsinva]

I use amsoil now but i have used mobil 1 royal purple and K&N as well they are all great filters.

[phess11]

Based on my research, I am using Purolator PureOne. Good quality for the money.

Very true. Laugh all you want, but the "cough cough" Fram Xtended Guard filters are actually a very good filter.
