View Full Version : 'Over-Sized' Oil Filters

On the 3.4L 3400-series V6 engine:

Stock oil filter = AC Delco PF-47

'Over-Sized' (bigger than stock) oil filter = AC Delco PF-52

just wondering what or IF there is a big benefit from having a bigger oil filter?...
In Theory (whether or not it applies in our case - ? ):

Bigger oil filter means:
More oil filter media before it will clog-up (longer lasting oil filter).
More oil flow (because the filter is less restrictive than the similar smaller size ones).
A little more oil capacity (which can mean the oil will last a little longer in service).
A little oil cooling effect.

I am using:
NAPA Gold 1036 oil filters (that are made by Wix) that are similar in size to the AC Delco PF-52 oil filters.
About 1.4" longer than the stock AC Delco PF-47 size oil filters for the 3.4L V6 engine.


Please Discuss or Comment on using an 'over-sized' oil filters , like equivalent size to an AC Delco PF-52 on our GA's.

Nothing but good. No other way about it. There're some 3400 cars coming into the shop that I wanted to throw a PF 52 on and add an extra .5 quarts of oil.

You pretty much hit all the benefits. A lot of us GP guys use a 4.3L filter for that reason.

just out of curiosity, what is the ac delco pf52 and napa gold 1036 meant for (what engine)

somebody here mentioned "us 4.3L guys use it for that reason" so these filters are standard size for say a GMC Jimmy/Chevy Blazer?

I for one have switched from the $13 K&N to a $7 Napa Gold 1036, which from what I've read is better designed (made by Wix).

For those using mobil one oil filters, the stock size is M1-101 and iirc the slightly longer larger capacity one is M1-201.

I use a M1-102 now myself because I have the oil cooler and filter relocation kit and it uses a different thread size... but I believe the larger one for that would be M1-202?

yeah i used a larger than stock filter too... it was actually cheaper than the normal one for my car, so its a win win form me.

in my mind, having a larger filter means a little more oil and a little more flow so its def a good idea if it fits and if its available.

(I was researching the Wix / NAPA Gold oil filter for my new G8 GT, & was using my Grand AM oil filters for comparison.)

Regarding Wix's oil filters:

Wix 51040 / NAPA Gold 1040 (similar to stock size AC Delco PF-47):
Beta Ratio: 2/20=15/31
Max Flow Rate: 7-9 GPM
Nominal Micron Rating: 19

So that means:
Beta 2 ratio = 50% efficiency at 15 microns
Beta 20 ratio = 95% efficiency at 31 microns
& it flows 7-9 gallons per minute max


Wix 51036 / NAPA 1036 (similar to oversize AC Delco PF-52):
Beta Ratio: 2/20=12/26
Max Flow Rate: 7-9 GPM
Nominal Micron Rating: 19

So that means:
Beta 2 ratio = 50% efficiency at 12 microns
Beta 20 ratio = 95% efficiency at 26 microns
& it flows 7-9 gallons per minute max


PS: & they flow about double what the stock AC Delco oil filters can.


Compared for the oil filter for my G8 GT:

Wix 57060 / NAPA Gold 7060 (similar to stock size AC Delco PF-48):
Beta Ratio: 2/75=8/22
Max Flow Rate: 10-12 GPM
Nominal Micron Rating: 21

So that means:
Beta 2 ratio = 50% efficiency at 8 microns
Beta 20 ratio = 98.6% efficiency at 22 microns
& it flows 10-12 gallons per minute max

Hmmm and I'm due for an oil change too...well actually a little OVERdue -_-, but I'll prob just get a wix filter instead of my usual ac del.

Wish I had seen prior to this past weekend when I changed my oil....

So if you use an oversized filter, you use 5 quarts instead of 4.5?

id be interested in this too. the stock filter for the subaru's is so freakin small.

biggest one i can find is this one FIL1356 for a 97 ford probe 2.5l v6
http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=470&LineCode=FIL&PartNumber=1356&Description=Oil+Filter+%28Gold%29

its 3.4" tall vs the 3.1" on the stock subaru filter for my 95 2.2
your 05 subaru filter is only 2.5" tall so the one i listed would be a nice step up.

no problem. i was bored and ive been meaning to do it. im not impressed with the size of the oil filter on the subaru.

there might be a bigger one out there but for your car the 3.5" one would be the equivalent of getting the pf-52 instead of the pf-47

i usually get the wix equivalent or the napa gold ones.
