I use Mobil 1 in all my vehicles and run oil for 7500 miles. My logic is by changing oil myself and buying it at SAMS CLUB or COSTCO, I can use Mobil 1 for same cost as a Jiffy Lube Oil Change with Dino Oil.
I also use it in my kids cars. When under warrenty, I did use dino oil (or blends) with shorter changes on my kids cars.
Vehicles:
1998 Corvette (use OLM) do get UOA done ocassionally (switching to Castrol Edge soon)
2001 V6 Impala
1996 Chevy Express Van 1500 (Custom Conversion) V8 350 cubic inches
2006 Nissan Murano 3.5 Liter V6
