Remember the new old filter, I found some information about it and part numbers:
http://www.sandyblogs.com/t...d-oe-oil-filter.html

I think I have 8 PF52's in my stock. My 2004 Olds Alero used the same filter as my GT so I stocked up, then I traded off the Alero so I won't have to buy any filters for awhile.

both new and old design are made?
Maybe so... But allot of store have 1 style in inventory... probably because package and filter says just PF52 and not PF52E.

I am able to buy the "old" style at Advance Auto Parts. Here is their part number: 5140668

So just so I am certain this is the oil filter size preferred for the 2.8lt engine that when installed you fill with 5 quarts of oil and its at the right full level? Just want to figure out what this oil filter gives you over any other.

Thanks.

The longer oil filter gives you the ability to run more oil in the crankcase to help with lubrication. There are no other advantages.

You cannot - under normal circumstances - just put more oil in the car over it's capacity. If you did, it would eventually have nowhere to go, and likely begin to cause internal damage as the non-traversing oil slides against the moving internal parts (typically the crank is the first area that would begin to see damge). Running the ACDelco PF52 in the 2.8L V6 allows an even five quarts to be put into the crankcase. Normally if you used the short filter and put in five quarts, you would risk engine damage, but with the longer filter you can warrant the extra .6 or so quarts in the crankcase with ease. It's extra piece of mind, especially if you are driving a Fiero that maybe has a minor oil leak that you cannot currently get to and want the extra oil running through for safety.

And for the 84-87 2.5L, to increase capacity (recommended change by GM). Plus, the longer filter is easier to reach

Thanks I just wanted to make sure of that before my next oil change since I was thinking of switching to this filter.

Autozone has the "old" style PF52 also; in fact its been a while since I've seen an Ecore PF52 at my local store.

Besides the Fiero, the PF52 is a nice filter in a number of other cars too. I use one in our Impala; it is MUCH easier to grab. The stock PF47 is so short and gets slippery with hot oil so its almost impossible to hold onto while seesawing it out past the fan shroud and various AC wiring and tubing. The PF52 is much easier to hold onto and there's plenty of room.

yup, I use the PF52 in the Aztek, 4.3L Mercruiser engine, Grand Prix... basically anything that calls for a PF47, I usually just get a PF52 if there is the room.

You can tell the two apart pretty esaily:

If you're finding the old design, they're probably old ones that have been on the shelf a while, or HOPEFULLY they changed suppliers back to the previous company.

I have seen the PF52E (new design) and the PF52. These don't look to be old stock, unless they had a ton of them.... maybe the warehouse had a bunch??

If you want the old PF52, just go to a good parts store and get a WIX 51036. I am pretty sure that WIX was the supllier to AC Delco for the old style PF52. Even if WIX was not the supplier, the WIX filter is the best replacemet you're gonna find.

So if it is the same as the PF52, why is it the best replacement filter? Isn't the filter just equal to the AC/Delco PF52?

I do think it is funny that people disassemble filters and compare them, yet there is no comparison on actual functionality, but just on looks. I have to say that "believe" the PF52 is better than the PF52E, but that is based on what I see and since the price is the same, I go with what I know. I like the larger container, I like the beefer metal for the threads, etc...

Anyone actually run a performance test on filters to see how well they function? Do they meet the specifications of the engine manufacturer?

I've heard nothing but good things about Wix / NAPA filters - and they are cheap to boot. The Napa Gold filter with silicone anti-drainback valve is $3.40 for the Fiero V6. Most other cars are about the same. As a bonus they are made here in North Carolina, just down the street.

Not sure why anyone would waste their time with that Fram garbage or Driveworks BS when the Wix filter is essentially the same price.
