I've noticed that somewhere between 45 and 50 MPH is most efficient. I get
somewhere between 35 and 38 mpg at that speed. Any faster or slower, and it
Temperature really makes a big difference, too. In the winter (when it's
between -10 and +10 degrees F) I get around 18mpg. In the summer, it's
closer to 22mpg

trash in a can encased filter. That's hard to do with an element type filter
like is used in the 3.3 Sonata. I looked at the Purolator / NAPA India made
version of the filter, and I was not impressed. I bought a CH9999 from
Wally-World, and took some pictures. The filter really doesn't look bad. In
fact, the actual element looks more consistent than the Hyundai filter. The
end seals (element to plastic) look identical, and the oil seals - both on
the filter, and in the bag for the bypass valve, and the filter cap look the
same. I'll try it, and see how it holds up.
Here's the pix. They are fairly high resolution, so they might take a while:
True, looks don't filter oil, but the sites that I've been able to find that
"tested / compared" various oil filters did rely solely on looking at the
construction of the different filters. None of them did any testing of the
filter's ability to filter oil. They mention things like cardboard end caps.
Also they found bad anti-drainback valve construction, crappy can
construction, and bad bypass valve construction. Also, just looking at the
pictures, you can see that the filter media looks realy bad. This filter has
none of the items mentioned. All of the functionality other than the actual
filtering of the oil is provided by the parts that Hyundai originally
provided with the vehicle, and stay with it regardless of what brand of
filter is used.
Given that one of the trademark signs of the crappy Fram filters is the
cardboard end caps - and these don't have them - it might be reasonable to
conclude that these particular filters are made someplace other than the
factory that makes the other Fram filters. As we know, Hyundai issued that
TSB warning about problems with "certain" aftermarket filters causing oil
pressure issues. Given the information about the poor quality construction
of the can type filters that's only visible after destructive disassembly,
it's obvious why those problems exist.
The only real question about these filters is whether the element holds up
for an oil change cycle. That will be easy to determine.
If you know of sites that have done other than visual testing that I haven't
been able to find, I'd be interested in looking at their data.
I'm not aware of any sources of unbiased data either. One of the few
companies that publishes data is Amsoil, but I quite frankly don't trust
them given their past (and I believe still present) marketing tactics.
SWRI is probably the largest test center in the country, but they only
provide data to the folks that paid for the test!
The pictures are very nice. In the pictures, it appears that both the
filter media and the inner o-rings (I think they are o-rings anyway) are
a different color from the Hyundai filter. This may be inconsequential
or it may mean that these materials are materially (pun intended!)
different from the Hyundai filter. I'd want to know if this was my engine.
They are. The O rings on the Fram are a lighter green. The filter media is
also a lighter color on the Fram. They smell different, too. The first
filter I took out of my 2007 Sonata had dark red O rings. The "Hyundai"
filter in the pictures actually came from a Kia dealer. Same part number as
the one from the Hyundai dealer.... just $6.00 cheaper.
the Hyundai filter. I just bought the Fram filter because it is a little
cheaper, and I was curious how it compared to the Hyundai filter. As I said
previously, I've seen the "made in India" Purolator filter, and I wasn't
impressed. This one looks pretty good.
