Update:
2012 Nissan. I think two loose bolts on oil pan caused it. Unsure.
2013 F150. After 2-3k miles either the Blue Devil (two bottle) additive in, still had a leak. Changed oil to Valvoline Max Life Blend. Drove 400 miles round trip. No leak. Seep, but no leak. No drips on my driveway.
Max Life for the win?
Combination?
No clue.
