Longer Oil Filter - Why Not?
I found a picture on here posted by KRUSS back in 2007:
https://www.thirdgen.org/forums/afte...ml#post3406534
It's showing an AC Delco PF1218 (a 5 inch long filter) installed on his '92 Camaro with a 305. As you can see in the image, there's a good 4 inches between the bottom of the filter, and the bottom of the oil pan, which means there is room for a filter of 9 inches long without any ground clearance issues.
The AC Delco PF932, and multiple other equivalents which are around 8 to 9 inches, should therefore be able to fit without problem.
Does anyone have any reasons as to why one shouldn't run this 2 quart filter on a Camaro? It is the same thread size, gasket size, and everything, as the PF454 and PF1218, just longer.
(I'm posting this in the TBI section because I would be installing it on my 1989 Camaro RS with the 305 TBI, so I hope this is the correct section.)

I have been using the K&N-3002 for a long time now.

Re: Longer Oil Filter - Why Not?
I also use the taller filter.
Mobil 1 Extended Performance M1-302.
Just be sure you "prime" the filter before you put it on.
My filter will hold around a Quart of oil.

Re: Longer Oil Filter - Why Not?
I have been using them too,in a bind if the parts monkey is younger than 35 just ask for one for a 1970 pickup with a 350.

Re: Longer Oil Filter - Why Not?
2 reasons: one, I blew up an L69 the first time I tried the long filter. Added extra oil and the engine was strong. Yeah, I know.
Second, I have multiple vehicles that fit, or require clearance for, a PF3980 filter. So I make it easier to shop for one filter, instead of a few, by changing the adapter.

Re: Longer Oil Filter - Why Not?
No one as mentioned the benefit if the additional quart of oil added with the long (2-qt) filter. For me that additional quart with out adding a larger oil pan is major for me.

Re: Longer Oil Filter - Why Not?
There's no cooling added. Given the choice between the long filter and a cooler, I'll take the cooler.
The short filter has plenty of surface area for filtration, unless you're driving through dust storms.
Assuming someone has an engine in good condition, and maintains it well, the big filter isn't going to help a thing.

Re: Longer Oil Filter - Why Not?
It may not help any, but it surely doesn't hurt I would think. I've also been using the longer filters for years. Recently found out the LS motors are the same way. Was at the parts store a few weeks ago getting oil and filters for the suburban and the wife's avalanche. Suburban has a 6.0 and the avalanche has the 5.3. Dude brought out 2 different filters. The 6.0 filter is longer. Just got 2 for that motor. Since both trucks are high mileage (suburban 400k, avalanche 200k) and use about a quart between oil changes, I look at it as I have an extra half quart when the low oil level light comes on

Re: Longer Oil Filter - Why Not?
I just can put that little 3 inch tall filter on my Chevy Small Block V-8.
Feels like a toy in my hand.
A little 4 banger maybe.

Re: Longer Oil Filter - Why Not?
( I'm with you on this. Extra oil somewhere else doesn't change the depth of the oil pan, height of the oil pickup, or height of the oil level sensor. )
That sounds right..
The main reason I like the larger filter is , lets say you have 6 qt. of oil in your car rather than 5 .That means you are filtering 6 qt. of oil during rotation of the oil through the system.
That's the hole point of the larger filter. To give you the extra qt.

Re: Longer Oil Filter - Why Not?
I use Fram Extra Guard filters and a PH30 PN. Does anyone know if they make or use the larger filter. If you do do you know the PN? I have been wanting to use the larger filter also.

Does anyone have any reasons as to why one shouldn't run this 2 quart filter on a Camaro?

2. No reason you can't run it. I install the taller filter whenever I don't have clearance issues. It's been done for decades. Won't hurt a thing. I also install the "long" 5" 1049 NAPA filter on some AMC, old Buicks and old Cadillacs, Intercoursibles, Olds, Pontiacs, and Rutebagas, if there's clearance. There often isn't clearance on newer Buicks, and I don't see a lot of AMCs, Internationals, or Studebakers.
3. Does not provide "better" filtering. Goes longer before getting plugged/restricted. The shorter filters probably provide some cost-savings to GM when installed by the millions--shorter, less-expensive filter to make, and you don't need the extra half-a-quart of oil to fill like you do with the taller filter.
As said, having more oil in the filter doesn't help the engine much. There's a little more surface area to radiate heat, and the oil filter element will go longer without plugging...but that's of little concern to us since folks tend to over-change the oil and filter. Sixty+ years ago, some folks only changed the filter every other oil change, and of course the engines created more sludge and ingested more dirt via gravel roads and the "screen" on the crankcase ventilation system back then anyway.
I think these people's heads will explode if you are actually talking about the Wix/NAPA 51794/1794 genuine medium-duty TRUCK filter. (Nearly 8" tall, over 2 1/2 inches taller than the "tall" filter these guys are talking about.) They're made by all the usual competing companies as well.
I'm fairly sure there's a still-taller filter that will screw right onto a typical Chevy V-8 oil filter adapter, but I can't find a part number. I haven't seen one in thirty years, so my memory may be fuzzy, but I remember thinking it was a foot long or more.

Re: Longer Oil Filter - Why Not?
Im the 2nd owner, 135k on L98, been using cheap off brand oil and filters since the 1st oil change back in 1991 (im friends with the OG owner). runs great, 150psi compression in all cylinders, plenty of power to smoke the tires, did intake gasket last weekend, still looked super duper in there.. change your oil/filter regularly
, dont fall for the hype.
