My Vette has a 350CI crate motor. The info for the motor says it takes a PF25 AC oil filter. The guy at the auto supply store says that number has been discontinued. I found something on line that said AC filter PF454 is the same as the PF25. Does anyone know if this true or not? Thanks much, Darrell

Yes it's actually improved with an anti drain-back feature.

I believe the Fram Ph-30 will also work for you. I know it works on my 69 427.

I think most any brand will be fine as long as it meets factory specs.  The secret is regular oil and filter changes.  

The crate engine, if it's a GM Performance crate engine will of course specify an AC oil filter since it's also GM.  Any good cross from another brand will work just as well.

I've seen a number of comparisons where someone buys an assortment of brand oil filters and cuts them open to compare construction.  It's amazing the differences between brands and how they're assembled.  Some have cardboard inside them, some have rubber bands holding the filter media together, etc.  There's no question some are made better, but with a regular oil and filter change schedule, they all do the same thing.  If you go with extended oil change intervals, yes, the better filters might make a difference, but essentially, they're do the same thing.

I like the 454. Simple stuff..I think it's bigger too.

All oil filters are not created equal.  The filter media and anti-drainback features just to name a couple of things.  I saw a report on Fram filters that showed them failing pressure tests.  Caveat emptor.  Wink

The topic of filters will have many opinions. The car currently has a fram PH30 installed from the previous owner. It seems to be working well. I will be changing the oil soon, and was just trying to get an idea of what other owners use.

I spend a few extra scheckles and get the K & N Oil Filter.

Maybe its overkill for my '79 L-48, but I like peace of mind.
 
I've also heard good things about the Napa Gold Oil Filters but I've never bought one.
 
Let us know what you decide to go with.

All I have to say is...if the engine has a warranty on it, use the proper Delco filter. Or do as you please.

We had a guy come into my buddy's dealership to redeem a oil change gift certificate that was a door prize at a fund raising benefit.

Long story short. The engine blew, the Chevy dealership blamed it on the aftermarket oil filter, went to court, lost case, paid out $4400 for a new engine. This was even after the guy admitted going 5,000 miles over the recommended service interval. <smh>

I used Delco filters on my GM vehicles, and Motorcraft filters on my Ford truck. That way there is no way they can say it was the aftermarket filter at fault if the engine blows up.

I've been using the K&N oil filters on my 350ci and I prefer them. I like the wrench off feature as it is faster to get the filter off during a change. I have used the AC and the Fram as well. PF-454 is just larger than the PF-25. We went to K&N because my local auto parts stores didn't carry the one's I wanted consistently. So I went on line to order. So I figured if I'm going to go thru the trouble of ordering on line I'd get something that isn't often in the store anyway.

I've been using Wix filters recently - they're what my favorite hi-perf local parts store (Baxter's for people in the area) sells.  I asked those guys if the extra $$ for the K&N was worth it and they said not really.  (Although I'd have to admit the wrench-off feature would be nice).  I don't come close to putting 3K miles on this car between oil changes, so more than twice the cost for a super-duper filter may not be needed.  

I've used AC Delco (engine warranty not an issue for me since I rebuilt my original) in the past as well as Fram, but I've also heard suspect things about Fram lately.

Well....I'll throw my hat into the ring, and say this....
I use ONLY AC/Delco oil filters on my GM vehicles. The only time I would use anything else is on a new build, where the filter would be changed in just a few miles. That's it...no other reasoning.
I have seen many a Fram filter blow across the shop floor on cold startups back in the day. Don't know if they are any better now or not, but ain't gunna chance it.
Wix filters, imo, are not very good in the filtration department. Don't take much to clog them up, and I have seen some with few miles on them that the element has collapsed.

Since I can no longer buy the "correct" PF25 for my '74, I use the PF454...it is a little larger, but not much.

I figure I will chime in just because FRAM deserves it....Twice in the last year, I have purchased a Fram filter as part of a package oil change deal - one for my 07 Mustang and another for my Silverado pickup.  In both cases, I could not get the filter to tighten up (I only use my hands to put them on) and it would just spin. Neither one was properly crimped and they would have just blown off under pressure. In a case with a friends car, a Honda, he was using it at an autocross and blew a Fram filter.  Let's just say their quality is not properly reflected in their excellent marketing campaign.  I won't buy any more FRAMs and wont use them if they are part of some package deal. Just not worth the hassle and worry.  I have 3 Corvettes and only use AC or K&N filters on them.  On my Mustang I use Motorcraft or Purolator (which have had very good reviews).

I use the PF35 which is the taller version of the PF25 and was used on the pickup trucks.  Never cut one open to verify that the filter element is actually longer also.  Don't know if they're still available tho as I bought a bunch several years ago on sale. 

Didn't know the PF 25 was no longer available.  Checked the O'Reilly website and they still sell the PF 25.  The PF454 looks like a very short filter.  Not sure what GM is doing as both my Tahoes have filters about the size of soup cans.  Disapprove

Edit: I see why you get the PF-454. OMG  The PF-25 and 35 are $28.  WTF

Yuse guys have me convinced - I'll switch out my Wix for the Delco PF454 next chance I get.

The last I had heard the NAPA filters are made by Wix.  I've been using them on the entire fleet for years without any issues (that I know of).  Only recently have I switched to a Bosch filter on "The Beast" as it is the filter of choice of a noted ZR-1 guru.
 
Was using Fram filters prior to the switch to NAPA's, also without any issues (that I know of).

You can buy a PF 25 on Amazon for $15 if you spend $25 to get the free shipping.  Has anyone used the PF1218 filter. It looks to be a larger version of the PF454.

On a related topic, what type of oil do you use?  I have been using "regular" oil (i.e., not synthetic) 10w-30.  I was once told not to use synthetic on these older cars.  Since the car is not drive much, I only change the oil twice a year.  Is that about what everyone else is doing too?

I am about to change the oil for the first time since I bought the car 3 months ago. The previous owner used Valvoline MaxLife 10w-40. This oil should be ok. I am thinking of adding some ZDDP suppliment. It is always nice to get some other people's thoughts on the topic. I am still new to the corvette. The car will not be driven very much, so it will only be getting an oil change once a year
