: Oil leak?

Everyone, can someone tell me if these engines are prone to minor oil leaks from the rear main area? I was looking under the car yesterday while it was on a lift getting a tire patched and saw what looked like oil staining on the pan. It's not leaking on the garage but it's just something I saw. What are your experiences? My LS1 used to shit seals constantly and I'm a little over-anxious about oil issues.

Some cars are experiencing this:

I had a minor leak but it wasn't coming from the rear main. It turned out that I had a defective oil-pan gasket. Dealer traced the problem, and fixed it under warranty.
