.... What I do have a problem with is hyundai and kia issuing TSB bulletins about aftermarket filters, and trying to deny warranty coverage on people due to not using OEM filters. ...
..... if you are using quality oil and changing it on the proper schedule, that filter really isn't catching that much to begin with.
I have no problem with KIA issuing the TSB on aftermarket filters, PROVIDED IT'S TRUE. So, do I have any way of knowing if what they say is factual and proven? Definitely not. But the bottom line is that it MIGHT BE, which is good enough for me. Perhaps KIA determined that certain aftermarket filters don't have the correct flow rate. They don't really tell us anything specific, and what I wrote is pure speculation about how they came up with that TSB. And your guess would be as good as mine.
I do agree completely about denying warranty coverage just because a non-OEM filter is on the vehicle. In my travels around the forums, I've read very few reliably sounding reports (with follow-ups), of either KIA or Hyundai actually doing this. So, IMHO they did not issue this TSB in order to facilitate warranty coverage denial.
Before you grab your pen to reply, be advised that I am typically not a defender of KIA, Hyundai, or any of their stealerships. Far from it, I'm usually on the other side of the fence. But I do believe in trying to call them as I see them; and I can't find a reason to criticize them for the filter TSB, unless it's someday uncovered to be nothing but a ploy on their part.
not sure why people don't just use the KIA filters. they are not expensive and you avoid any hassles with KIA should you have any engine problems related to oiling issues.
^^^ this is exactly the approach I've taken for the 103K miles on our Forte. And now that it's out of warranty, I've decided to continue using KIA filters. They've worked so far, so why roll the dice at this point.
Here's one other thing to give some perspective to what I wrote above. I also have used Fram filters for many years on other family vehicles, and still use them on some of our older ones. Never have had an engine issue using them, and will have no problem continuing to use them. Except on the KIA. Just in case.
