About a month ago, I did an oil change on my Kia Optima. I planned on a 6 month/7K OCI. I got some Pennzoil Platinum from my dad for Christmas, so I decided to use that and a Bosch D+ I picked up with the 5.00 rebate.
On the 2.4 I-4, the filter is oriented vertically, with the thread-end up, so ADBV failure shouldn't be too much of a problem, one would think.
Anyway, right after the change I noticed a little more lifter noise, especially after the engine is warm. I assumed it was the filter. My theory was that maybe the D+ has too dense of media, but it was just a less-than-educated guess.
Having seen many posts on BITOG, I thought it may be worth my time to try an OEM filter, so I picked up two (which didn't come with oil plug washers. I've always thought that dealer was shady.)
This weekend, I replaced the Bosch D+ with the Kia filter, which is very well constructed. Much to my dismay, there was no change in noise.
I can't tell if its the PP, or its just a case of BITOG enduced paranoia. Maybe the noise has always been there? Its not all that loud. My brother-in-law's 09 civic is a lot noiser.
I will see if the noise is the same the next time around. I am going to try VGB and a Puro Classic next time, just to see if the noise chagnes. Going forward, I will probably switch to Kia filters, after I exhaust my supply of Napa Golds.
