AC Delco oil filters?
Phil Nelson
I bought a PF13 because the K-Mart book had the wrong filter listed for
my '90 LeBaron GT with the 3 liter V6 (they listed the same filter that the
4 uses). It looks like it will fit, it is the same size as the FRAM PH16
that I ordinarily use, although the AC box says it crosses to FRAM PH3963.
I don't plan on putting this on my car without some more investigation, but
I wonder if anyone has an opinion about the quality of the filter?
The side of the box is very interesting:
"The hotter temperatures, higher flow rates and tighter clearances of today's
engines demand improved oil filter performance, and AC DURAGUARD Oil Filters
provide the best value in high tech filtration for high tech engines."
If I may translate: "Modern engines need finer filters, AC is the cheapest
finer filter you can buy."
The thing is, I can buy 2 of these for every FRAM, and change twice as often.

AC is the only filter I use, and that's on my GM, Toyota and Suzuki cars.
My friends use AC on their Jeep. FRAM is the one I stay away from.
They seem to be more cheaply built that AC-Delco ones. That's my opinion
after having used both.
Filters as it turns out are quite interchangable, and I have seen the
same part number crossing problems you describe. For example, a AC
PF53 on the AC box will cross to a FRAM PH-xx, but on the PH-xx box,
the cross comes back to a PF54. Then GM changed the spec on the Geo
Tracker from PF54 to PF1245. So we have PF53==PF54==PF1245.
The PF54 has a anti-drain back valve, the PF53 doesn't. The FRAM PH-xx
filter does NOT have the valve, but FRAM will claim it replaces a PF54,
which DOES have the valve.
Here are some other crosses, depending ONLY if there is physical room
for the larger filter. I always install the largest that will fit,
more media means more filtering. Ordered small to large physical size
(if different sized):
PF25->PF35
PF40->PF47->PF51->PF52
PF53->PF54->PF1245
K-Mart has AC-Delco Oil filters on sale for $2; I bought 12 of each
size I use. The PF54 costs $7.99 at Pep Boys.

One other thing to consider... If you do not use the number filter that
the filter maker shows for the car they WILL NOT WARRANTY any failures
that result from a filter problem...such as a tear or grove in the
gasket that causes the car to loose all its oil...that has happened
BTW...Standard oil change on a older Lincoln...no leaks when it left
shop..10 miles away while on frwy customer observes thjat oil suddenly
comes on..by the time he gets off the frwy the engine is making terrible
noise...after phone call etc. we tow car to out shop and check it
out...oil all underneath car but no sign of where from... fill engine
with oil, start car and observe oil SQUIRTING between filter and block.
Remove filter and find that it the gasket NEATLY CRACKED! Call filter
manufacturer and they send a rep over. He checks car, takes the filter.
3 days later they ADMIT to a faulty gasket and pay for all necessary
repairs. ( short block ) about $1500..Included with the papers of the
settlement was a copy of there warranty...and it spelled out quite
clearly that this type of incident is only covered when proper filter
application is used.
Soap box off!

Be careful on the PF51->PF52 usage. The PF52 has an anti-drainback valve while
the PF51 does not.

suppose I should have the -> point the other way ( <- ).
The PF47 is anti-drainback valved; the PF40 is not. The only
difference between the PF25 and PF35 is the can size. The PF35 is about
33% taller, meaning more filter capacity. Make sure you adjust for this
when checking oil levels after a change.

GM specifies the use of the PF47 oil filter with thier 1988 Bonniville
with the 3800 V6. The threaded end is pointed straight upward. Why
would this require an anti-drainback valve?

may not "require" the PF47, but since it is a very popular filter and is used
on the the 3800 and 3.8L engines it was specified. Using the PF52 (if there is
room) will give you more filtration area than the PF47.

The various versions of the 3800 angle the oil filter out of the way of
whatever chassis or accessories they're working around. GM probably
decided to simply specify the anti-drainback filter for all
applications.

Okay, the PF47 and PF52 are anti-drainback, and PF35 is a taller can.
Could someone do a matrix of what the differences between the different
numbers is? (ie, size, thread and anti-drainback)
Thanks,
