Several Months ago, there was some discussion about aftermarket oi filters
for the Sonata. I had purchased a Fram PH9999. I took severa pictures of
it - the filter, O rings, and took similar pictures of the genuin Hyundai
filter. Matt Whiting had the following to say: "The picture are very nice.
In the pictures, it appears that both the filter media and th inner o-rings
(I think they are o-rings anyway) are a different color from th Hyundai
filter. This may be inconsequential or it may mean that thes materials are
materially (pun intended!) different from the Hyundai filter. I' want to
know if this was my engine.
Well, Matt hit the nail on the head. Around the end of August, did an oil
change, and installed the Fram filter in my 2006 Sonata. All wa well until
I noticed the oil stain on my driveway yesterday. (My wife drive the car).
This morning, I looked under the hood, and found oil had bee leaking from
between the cap and the filter housing. I tried to give it a turn and found
it tight. I started the engine, and the entire filter housing wa almost
immediately covered in oil. I took the filter cap off, hoping tha it wasn't
cracked
It wasn't. The O ring for the cap was flat. It actually ha hardened. I've
changed the oil in the car like 6 times now, and the Hyundai O rin was
still round and soft (flexible) when replaced. The Fram O rin actually is
now flat on the outside, and was really hard. I have pictures o the Hyundai
O ring I replaced it with up against the Fram O ring I removed. M server is
currently dead, so I anyone's got either a way to host them, o suggestions
as to how I can link to them, let me know (my email address i valid), and
I'll either email them to you, or follow whatever instructions s everyone
can see
I think a contributing factor was the cold weather we had the pas few
days - pretty close to 30. I would have noticed the oil on th driveway, and
the way the oil flowed out, it would have made a really big puddle and ran
the oil level down in the car. I suspect that as soon as the oi warms, it
quits leaking
I figure there's no point in trying to contact Fram about this - can
picture how their customer service would react

Wow! We have covered several areas. I have a BSEE
MBA and Masters in Systems Engineering degrees. Have over 30 year
experience in product design and now work for a major airplan
manufacturing company (many billions) as an Avionics Engineer.
To evaluate an oil filter, one would need to know the specification
of the product including the tolorances of the parts, the materia
trace, the characteristics of the paper used in the filter, th
quality control system, etc. We do not have access to that kind o
info so just have to go by hearsay and experience
I have found a couple of websites that have evaluated oil filters bu
just take those inputs with a grain of salt. Also, I wonder abou
the value of the filter with the high detergent oils we have today
Medical question: I have an HMO and have had a couple of majo
surguries over the years. One should be educated and well informe
before listening to any doctor. I investigate the ones I use ver
thoroughly before using them. Money is not the determining facto
but past results are indicative of their quality.
When judging the quality of almost anything we purchase or use toda
we are limited by time to do research and lack of availabl
information
According to my training, a product should meet the liste
requirements but not be overdesigned to the point of waste. I'm sur
this is the attitude of Hyundai
