Engine oil Motorex or Pentosin

I would stick with oils like PENTOSIN/LUBRO-MOLY/CASTROL GERMAN/MOTUL/ This one is easy. Anything not made in the US and is 100% synthetic. I use Pentosin high performance 5w-40, 502/501/500 approved oil.

pentosin/pentosynth 5W40 here, changed it 1K miles ago (second run on this oil), great stuff ecstuning.com sell it for ~28 bucks for 5 liter. I like it much, much more over the castrol from dealership (used that too and after 2K miles changed back to pentsynth). I'm very happy with it.
