2015 Hyundai Sonata 2.4 with 20k miles on the replacement engine. Oil had 3,200 miles and the filter had 6,200 miles.

Oil in and out: Mobil ESP 5w-30
Filter off and on: Carquest premium 85334

This is the first time I’ve had this issue, but it looks like the filter was leaking some oil around the gasket. I’ve had this car for 164,000 miles and this is the first time I’ve had this issue. It almost looks like the silicone gasket wasn’t think enough in that area. Anyone seen this issue with these filters?

When you removed the filter did you notice a bunch of oil in the grove the arrow is point to? What's the orientation of the filter when mounted? It's also possible that the crimp seam is leaking instead of the P-gasket.

^^^ Also refereed to as a "torque stop" design because they are torqued until the can hits the filter seat and stops.

Really hard to tell, when I removed the filter oil pours out over that area.

Yeah, that would make it hard to tell. What was the orientation of the filter when mounted? Was there more oil & dirt on one side?

That filter has a molded gasket, also sometimes called a P-type gasket. The installation method is different than a regular “laser cut” gasket. With a molded gasket, you tighten it down until the oil filter housing appears to be touching the oil filter mating surface.

I hadn’t seen that. However there is no way it wasn’t tight. I installed it the same way I’ve installed all the previous premium guard filters. Seat them and tighten them down tight by hand. Not that I have a super grip but it takes a decent filter wrench to get them off. I actually wondered if I overnighted it, but it doesn’t seem like that is likely.

Yes, just that one area, maybe 1/4 of the filter. I honestly didn’t notice it until I went to cut it open, so I’m not sure what direction it was on the engine… I know the bottom of the filter was clean, because I looked up at the filter before removing it.

Is the filter mounted vertical? Base up? Or how?
 
Yes, straight up. It’s kinda shielded so that’s why I didn’t see the dirty side.

If it's mounted vertical with the base up, and was only dirty on 1/4 of the side, then I'd suspect the crimp seam around the base in that area. If it was the gasket, that groove I pointed to earlier would fill up with oil and most likely leak around the entire outside (or at least more than 1/4 of the circumference) of the can instead of in just one area.
