My mom can care less about oil, my dad has been insistent on Castrol in the past and almost lost it when a mechanic poured Pennzoil Multi-Vis 20W-50 into a Mercedes they had in the past.
The most recent oil change I did for them was ServicePro 5W-30. I said to my dad it was approved by GM and made by the same company who holds contracts with Wal-Mart, AutoZone and most of the parts store chains. He said, OK as long as the car still runs good.
For me, I use any major brand but for friends who want cheap and good, I'll pour SuperTech and not flinch.
