I use Royal purple and PureOne filter. RP claims to raise hp and tq by 6 and 8 respectively do I feel it on a car that makes just over 200 hp, no. I do notice that I can run for 10k miles and still have oil in better shape than what you will find on the shelf at Wal-Mart. PureOne filter is equal to K&N as far as filtration goes(both I think are rated to trap 30 micron) PureOne doe offer a better multi pass filtration. in other words it takes more millage to clog it.

Purolator and only Purolater here. Best value for the money, IMO.

I uesd Fram 3387A since I bought my first Bonnie in '03, and I never had a problem...then I became a member of this forum There seems to be a general concesous about Fram.

IMO, the PF 47 or 52 is a good filter...as long as it does not have that &(*^% plastic core. If you look throught some of the Big Block Chevy forums, there are guys who puked motors from the plastic core collapsing and blocking oil flow.

I have been using Napa Gold 1040 for the last year, and it works good. It seems to hold up good to molases, which is what motor oil becomes on a December night in Alaska.

Proulator seems good; I have no complaints.

I don't touch Penzoil or Supertech. I'll go Fram before I put either of the two metioned in my shopping cart.

I look for 3 things with an oil filter: 1. Made here in America, 2. No plastic *(&^ core, and 3. Anit-Drain back valve (which I don't think Fram has)

Hope this helped

I had no idea that the plastic cores clog filters like this. Is there a list of filters that avoid plastic cores? Also, even though the plastic cores are fairly bad, couldn't you make a case that the core had ruined the engine and then have AC Delco get for you a new/reman/used engine?

What is the rate of failure of the plastic cores? Is it greater than the failure rate of Fram filters? If Fram filters also use plastic cores, then they can all easily be disbanded. From what I have read here, the best choice would be the PureOne PL24011 filter for both lower cost and great quality.

How about oils that have higher detergency than others? I believe Mobil 1 and probably Amsoil have the greatest longevity over time, and probably Pennzoil has a generally short life. This is all by what I've heard, and since this is a filter thread, we may not need to debate it much. But please correct me if I'm wrong.

Here'* something pretty cool:

There is a ton of actual data that can be found. There have been lots of oil filter/oil discussions here and while trying to encompass everything..it appears you have the same thread repeating itself again.

Here'* my take on things. Run what you would like and can afford. Many people have their oil changed at the cheapest place every 3,000 miles and run 200K w/o issues. I know, I'm formerly a member of that club when I didn't have a place to change my own. Ask anyone...I'm the last person to tell you I'm easy on any car I own. 4cylinder or 8...doesn't matter.

There is a difference in the AC Delco filters...one is stickered and one is painted for a label. The substandard one is probably made by Fram with a Delco name.

Sure you can up the mileage on synthetic oil because it doesn't break down like conventional and sure you can run longer on a better filter. Would I personally???? NO WAY. I've opened up plenty of motors, including my own and have seen that longer intervals allow more buildup on the internals. Frequent changes prove out with clean internals. At 140K my motor was a little dirty and gunky inside at 180K it was sparkling clean inside.

Currently I use Mobil 1 (From Walmart in the 5qt jug) and a Napa Gold 4.3L oil filter. I also have a ton of mods and very little tread on the front tires. My car gets what I can afford to give it for what I expect to get from it.

You may hear that changing to synthetic causes oil leaks. This is untrue, gaskets will not break down and leak because of a change in oil. They will leak because of gunk being built up and sealing a previous leak. The detergents in regular oil can break down the gunk if changed frequently enough.

If you want more data, pm Daman. He cuts open every oil filter he uses. If you want oil and filter analysis from someone that has experience with them and has seen nearly every one out there...he'* the guy.

There will be plenty of people saying they disagree wtih my book of babble here.. that'* cool, we all have different opinions and in my world when i change my oil it'* dirty at 3K. Also it has the same consistency as when it goes in.. should have plenty of detergents left in it when it comes out. Change the oil when it has some life left and you know it'* still doing it'* job. If you change it when the oil is all used up and spent.. then you are running your motor on crap and still expecting it to perform 100%...what type of logic is that?

Wow. Awesome post. Thanks a lot! I really couldn't agree with you more.

And don't worry - I don't change the oil when it'* crap. I've seen that Mobil 1 maintains its great Mobil-ness even at 5K miles, so I do 4K-mile intervals. The Extended Performance 10W-30 by Mobil 1 is "guaranteed' to last for 15,000 miles, but I can't trust it, not even though I love the company. I know 1337ssei runs his Extended Performance oil for about 7-8K miles per oil change with a Mobil 1 or K&N filter. He seems all right with it, and only puts about 1500 miles on his car every month.

So, I've seen Amsoil on this forum, and that'* how I found it. I have not used Amsoil products (unless they were repackaged), but I am interested. It seems they're online-only, but they claim they have very comparable filters. I've seen some people here don't own Bonnevilles but hang around to market these products. How do Amsoil filters differ?

I'm going to PM Daman right away.

My input for what its worth...

I always used to run AcDelcos exclusively in every car I ever owned, they are made by champion labs last I checked well about a year or so ago champion changed their design to what they call "e-core" basically instead of the metal insides it is now a plastic cage. I had no real issue with this till I put a new PF454 on my camaro, all was well till about 1000-1500 miles into the change where I lost over half my oil pressure, at idle it was almost zero PSI, and the most I saw in that time was 30psi. now I figured that it is an old car, and the engine might be ready to die, so I changed the oil, using the same brand and weight, but with a puroilator filter, and instantly got my oil pressure back, now over a year later and god knows how many miles it hasn't gone that low. Since then I haven't touched any of the new style AcDelco/Champion filters.

We all know fram is junk.

I like NAPA Filters, I know the "Gold" line is made by Wix, I believe their cheaper line is as well, but I am not sure.

I stay away from STP filters as they are also made by champion labs.

I like the puroilators myself, that is more or less exclusively all i use.

Daman:
Would you say that the Fram Extend Guard and Fram Double Guard filters are in the same class as the Fram Extra Guard and the Fram Tough Guard filters?
