A compromise is inevitable, esspecially if you are seeking the absolute (I'd think that probable only in isolation).

Even so, how many change other related perameters to make use of the pluses appearently gained by the use of found product? Ah, more testing.

There are so may other things that can have an impact on the final result(s) (and by the way, how many know what that is???).

I for one, like to know what's going on, and because I play a role in maintenance and change parts, fluids, etc., I have some responsibility in the overall health of my investment (cash and time). I would like to feel confident and to be able to give myself a pat on the back a time or two.

With that said, I'm not going to thrash the car around much anymore, and am to keep my eyes on the road and those in my immediate vacinity.

Still...I find myself troubled at times by the potential instability in understanding that marketing can play against an otherwise suitible chioce. I guess that may lay with the sense that one hasn't heard/found the whole truth. Well here I am guys!

Question for the sake of easying concern, because you want to learn, and/or just plain enjoy yourself with helping to contribute to the broadening of knowledge by encouraging others to share what to them is perhaps thought "common knowledge."

Rest easy, and enjoy the holiday season. We've made it this far so we must be doing something right!

While I realize discussions about some of the issues you both raise can be the "meat and potatoes" of the oil discussion thread, to me there is really no compromise when you talk of flow. Maximum FLOW if you can help it. HIGHER than Maximum Flow, if you can aid it in anyway. Specifically the oem oil filter is first and foremost a lubrication flow aid and pulling up the distant second is "filter". You can see it in the oem design. If there is impeded flow that reachs (X) psi, the bypass valve in ANY filter kicks in.

So that I don't appear to leave no place to go on this, "real" filtering tends to happen on the bypass oil filters and preoilers for app 400 aftermarket cost.

Or unsuitable choice(s).

"Pay me now, or pay me later". Fram.

"Racer's Edge" STP.

Although, I dunno, maybe for the day, STP was ok, but I always heard "gummy" stories about the stuff.
 
Wow that is a 6 of one half doz of the other! If it were me, I would purchase on price. Both are well made "commodity" oil filters. As an aside, most know the AC Delco is considered the OEM recommended brand.

My GM product/filter nexus is a Corvette Z06/AC DELCO PF44 filter. (this has since been superceded by another AC Delco PF46, upscale is the UPF44) Buying was almost a total no brainer, since a local big box retailer was selling the filters at $2. per. I bought a slug of them.(12 ea? as I recall)Normal price is something like 4 to 6 per?

I hate to disagree, but disagree I must. OEM (the ones that come installed on a new motor from the auto maker) Are of a higher in filtration and equal in flow. The OEM wants to make sure all the junk that is in a new motor is cought as soon as possible. The AFTERMARKET filters that are purchased through the dealers are meeting or exceeding the manufactures specs for filtering and flow charastics. for a broken in engine. Yes, there are two different sets od specs.
 
I am going to stick with Wix. They have good filtration, good flow, a silicon anti-drainback valve, threaded end bypass valve, and are widely available at non-chain auto parts stores and at NAPA (NAPA Gold).

Ok, which is better oil filter for the GM 5.3 V8..a AC Delco or a Puralator PureOne? Thanks

If it's a vertical filter mount, the AC Delco is better (to me) only because they have no ADBV. The Purolator & Wix aftermarket brands for my vertical mount GM oil filter does contain the "unnecessary" ADBV. That's why I stick with the AC Delco.

What about horizontal filter mounts? Which is better then?

I prefer the Pure Ones lately - ever since GM started demanding more for less from it's suppliers.

The best deal on filters right now is buying online. You can get Wix (NAPA Gold equivalent) sometimes for under $4.

Wix Filters right here
 
Ditto on Trip 7, I have been dealing with Filter1 for some time now and they are great. Check what Carquest, NAPA or Amsoil gets for a Wix filter, then check the Filter1 price. It is usually less than half and there is no shipping (for a $50 total order of all Wix filters) or sales tax(unless you are in NY). The Stratopores for my Cummins were about $20, now I pay $8 for the Wix XE equivalent. The regular Cummins filters were $10 from NAPA, $4 from Filter1. Best deal on a quality product IMHO
 
I am a mechanical engineer. I can cut apart filters, study media, look at designs, but I still won't have a fraction of the information that's available to GM for my GM cars. I stick with AC for that reason. There might be better filters, but their certainly will be worse, and how would I know for sure which is which? I stopped agonizing over the filter details and decided to put my trust in the GM engineers that spec the OEM filters. They might be wrong, but they have a better chance of being right than I do.

I did not say all AC Delcos are without ADBVs. I just said the PF-61 used on a vertical mount oil filter application (3.5 L5) does not have an ADBV.

On that truck, there is an oil channel above the filter that releases a few ounces of oil also. It makes quite a mess when changing the oil because GM put a suspension piece right below the filter with a cavity in it to absorb oil.

As a result, I plow thru it with a 1/4" drill bit at the bottom-right side of the filter to drain all the oil inside neatly before unscrewing it.
