Mine has the slightest leak that I noticed 6 months ago, seemed to stop, and is now leaking just enough the get the one of my bolt threads wet with oil. But oddly enough it doesn't leak any onto my driveway (probably drips when I hit bumps in road), nor do I lose any significant amount between oil changes.

I searched, and found very little info as to if this is a common occurence on our cars (even though I do know of atleast 3 threads that mention changing the oil pan gasket).

 

Yes, just recently.

Just get it fixed. My mechanic said seals need to be changed once it past 100xxx. If you're on a budget then you can wait it off until it's major (ex. your whole oil pan has oil all over it). I got mine changed as soon as there was a leak (like they say... fix it before the problem gets bigger). Any questions... feel free to pm me.
