Another bad situation is physical damage to the oil pan/pickup (think offroad stuff). The "good" situations are low rpm grocery getter applications. Factory parts installed by the factory in factory applications do well as a general statement.
I have also had a Moroso pickup tube fail from fatigue. When I went to buy a replacement, they had a brace added, so I wasn't the first one to have the problem.
