New Oil Filter For Me!

Jelly · Feb 10, 2004

Well, I have been using SuperTech filters here lately, but really haven't been that impressed with them...sure, the cost is low and they are still construced better than the Fram, but I've been having problems with what I call "sporadic operation...thinking maybe a malfunctioning ADBV".

One day, you'd go out and start it up, and no noise (tick-tick-tick noise of no oil). Next day, you'd go out, and car would make a racket for sometimes a few seconds, and even a few times for maybe a minute.

So with that in mind, and based on a little research, I went over to Advance Auto and picked up a PF52 ACDelco.

First off, as noted by the "weld marks" on the filter, this is definitely not a Champion Labs filter...

Second, the number of holes in the tube looks to be just as much as in the SuperTech filter, but MUCH LARGER.

Lastly...actual use. Vehicle is now quiet as can be every single day on startup (using the same oil as before).

All I can saw, at least juding by construction and actual use, appears a much better filter than the Champion Labs filters.

And guys, if you look up poor college student in the dictionary, you'll see my picture (I just have very generous parents...thank you)...if I can afford a $3/filter, you can too!

Your thoughts?

Also, I've heard AutoZone sells an AcDelco filter as well...gonna go over there tomorrow and check it out to see if it is any different than the one I picked up at Advance.

I just changed the oil on my 4cyl Camry. The car was still warm. The AC filter was dry, no oil left in it like with ST. No more ac's for me.

I would be interested in where you bought it. Ac is heavily counterfeited. Maybe it wasn't a real AC.

Did your ACDelco filter look like the one in my pictures above?

Here is another picture:

I think this is one of those Delphi-sourced ACDelco filters...

Spector · Feb 10, 2004

I just used an AC Delco for the first time during a cleaning cycle of RX. I cut it open for a look see. Normally I use the Amsoil SDF 20.

What impressed me was the small size of filter media, I didn't measure or anything, just appeared so much smaller inside, well length of media tube.
then the SDF 20.

It operated fine but was only on there 1500 miles. It also uses a smaller, what appears to be a non standard filter wrench, the cap one I use, well, none of the cap ones I have fit the stupid thing and I had to use a clamp type wrench.

I've noticed a number of times dry used oil filters at oil change time are reported. That is, they report the old filter they are replacing comes out dry. Will someone try to explain to me how this can happen?

Just went to advance Auto parts yesterday. It apears that, at least there, the following filters are not made by champion: PF-47, PF-52 and PF-59. The rest were champion, as well as all the ACs at Autozone.

I have one of these cut apart on my site:

I believe that this is a "delphi-style" filter. I did NOT like this fitler as much as the champion. More info to come soon.

My 4 cyl camry is usually dry too.
filter mounted updide down (threaded end down.)
i think the oil just drains out the center tube,

i thought the anti drain back valve was designed to keep oil in the ENGINE (ie oil could not drain back into the filter. )
NOT in the filter????

In any pumped liquid system, the oil or whatever flows upward as long as the pump is going. When the pump stops, the liquid is free to flow back down through the pump. In a tight system, a one way valve anywhere in the system will prevent the back flow regardless of twists and turns. Most engines rely on a rubber flange inside the oil filter to keep oil from flowing back out the inlet oil holes. Otherwise, all the oil both in the filter and the oil passages above it would flow back down to the crankcase leaving no oil flow until the pump refilled everything on start up. Oil could even siphon out of an inlet up mounted filter.

Many of us like to prefill the oil filter to reduce the time it takes to refill the system on start up after a filter change. A working ADBV keeps the filter and passages above it filled with oil ordinarily.

I have discovered my 02 Cavalier with the Ecotec engine does have a hidden ADBV somewhere, and a defeat that lets the oil out as soon as you loosen the filter cap. I wonder if some of these dry ''threads down'' filters have a similar mechanism? Perhaps check to see if more oil comes out the pan drain when you loosen the filter. An OEM filter without a ADBV might be more likely to work that way than an after market one consolidating numbers with ones requiring an ADBV. Maybe the AC comes off dry because GM designed it that way like mine. The question is, do you get start up noise routinely?

Hey, I recognize those pics!

That is the filter I use. I believe it to be Delphi.

With a filter mounted in this position, there is not way to hold the oil in the filter even if it had an ADBV. The ADBV would be on the bottom of the filter in this position and the oil would eventually leach out thru the media and out thru the outlet (center hole). The ADBV relies on the oil pressure to hold it closed. Try it, fill up the filter and place it in a pan like its mounted. Over a matter of minutes to hours, it will be empty. Apparently not a concern since the auto manufacturer designed it this way. ITs possible the OEM filter is constructed differently and thats the only filter that will work?

Filters mounted with the inlet/outlet facing down are the exception, not the rule. In over 30 yrs of dealing with cars/trucks I can recall very few like this.

"Filters mounted with the inlet/outlet facing down are the exception, not the rule. In over 30 yrs of dealing with cars/trucks I can recall very few like this."
===========================
i think all the 92 up 4 cyl Camrys (maybe all the ones in the 80s too) are like this (threaded end (hole) is down)
. 95% of all camrys are 4 cylinder so there are a lot lot lot of them on the road.

The AC was bought at Advanced Auto, and was made in the US. Whenever I use an ST, it holds the oil in the filter and when I change it, it drips all over the place. The AC was dry. I went to the AC because I thought it may be a better filter, but was disappointed. The AC was with a Mobil 1 oil change. I now have an ST with Havoline Synthetic.

Sorry I mistyped and now can't edit the message.

I meant to say I did NOT like this filter as much as the Champion style. It apears to have less filter area and no spring.

I have never had a problem with cold start problems on any Champion filter. They seem to have a much studier ADBV than other filters.

In my Camrys, I always try to use OEM Toyota filters - this weekend a brand new 90915-YZZA2 must have been defective as the ADBV did not work. The car (4 cyl) would start up and clatter until the oil pressure built up and filled the filter. I had a brand new (gasp) Fram filter in the trunk and decided to give it a go as the Toyota filter was not working right. When I yanked the YZZA2, it was dry - I expected to have the normal dump of oil over the front of the engine, but it created no mess. I then popped in the Fram PH4967 to test the next morning. (It's been pretty cold in Long Island this winter) Luckily the new Fram's ADBV appears to be working as advertised as the car started up nice and quiet, no clatter until the oil pressure built up. I had written Fram before I put the filter in, and asked about the ADBV - a helpful rep advised me that the unit had one. My previous experience with Frams on the 4 cyl. Camrys had not been good with dry starts. Until the next oil change, the Fram stays in. I picked up a AC Delco PF1233 as well as a Purolator PureOne PL14475 to try some other time. My image of the perfect OEM Toyota filter has been tarnished a bit.
