Great insight on oil, bore scoring, etc.

Lake Speed Jr. discusses oil, air filters, bore scoring, etc. on Porches.
If you're not familiar with Lake, he's a Tribologist. He studies engine oil for a living.
This is a long video, but definitely worth watching. The really good stuff starts about 37min in.
