I've used a bunch of different oils including Castrol Edge, Amsoil, Valvoline, Mobil 1, and Liqui Moly. All Euro spec. All 5W-40.
I was trying different oils because our Tiguan burns oil, and I wanted to see if any particular brand would burn less.
So far, Mobil 1 Euro 5W-40 burns about half a liter every 1000 miles, while all the others burned about 800 mL. So I'm sticking with that oil for now.
