WalMart AC Delco PF48 filters sale

[TomPierce]

Wandering thru the WalMart this morning when I came across a stack of AC Delco PF48 oil filters for $3.48. These were on the 'auto bargain' shelves with the other auto stuff they are trying to get rid of.

So I grabbed a bunch to stock up - I now have filters enough for now thru the 210,000 mile oil change.

You might want to check the 'bargain bin' next time you are in WalMart.

I didn't even know they sold AC delco filters. It's been a while since I've checked though, because I've also got enough oil and filters to last an eternity

I saw PF48 filters there the other day. I'll stick to the NAPA Gold filter I've been using, it's made by Wix and it's better than the GM filter.

Correct. Unless you get some UPF-48 filters like I did.

Thanks for that info

Tell me why wix is better than acdelco. The delco has a spring in the bottom that could be for two stage flow

i think 3.48 might be better than dealer pricing on these. i'll have to go check it out. i havent seen ac delco filters at walmart either, but im not big on shopping there. i've noticed stuff with the ac delco name popping up more and more since gm sent them off on their own. like the aa batteries at schucks, etc.

That's what was determined by cutting various oil filters open to examine them.

not sure what 2 stage flow is...? IIRC, the spring that almost all oil filters contain is a bypass designed to allow flow when the filter is blocked. The real differences in most filters is in the amount of filter material, the material that the bypass valve is made of, and the case burst strength.

I was told once by a GM engineer that The AC Delco filter had several advantages over most filters. He said that the inlet holes had a larger diameter which allowed a higher percentage of oil to be filtered. Secondly he said that there is back flow valve that keeps the oil passages charged when the engine is off. This means the oil is flowing faster at start up. I know that many high performance filters have this same feature. To know if your filter does, just note how much oil comes out when it is removed.

I can't back up any of this with any documentation. I just want to use the best I can and the info I was given seemed to make the AC Delco better.

If there is some solid benefit to using another brand, I would like to know. As a point of interest, I never let my oil get dirty before it is changed. I probably spend more money than needed because of this.
