Wow, that's a bit stalkerish. Good idea for the people that will actually look for data. I wouldn't be surprised if someone replies to this thread and asks if anyone has seen any uoa's on GC or Mobil1 0W-40. I wish I would have done a uoa on the WRX after it was stolen and recovered.

Motul has several 5W-30's and the Eco-nergy is on the thin side, although it does have the old school API SL additive levels.
Product Data Sheet (mm2 is pretty much the same as cst):

30 weight oils are between 9.3 and 12.5 cst's at 100C. Euro spec oils (and usually racing oils) are the thickest 30 weights. Euro oils also have a thicker High Temp High Shear viscosity for better shear stability (ACEA A3). Of course, you can't have your cake and eat it too so no ACEA A3 oil meets ILSAC GF4/GF5 Energy/Resource Conserving specs.

I would pick a higher HTHS viscosity over a higher kinematic viscosity at 100C. Wow, I just noticed the Motul Eco-nergy HTHS is now 3.4 which is the highest I've ever seen in a non ACEA A3 or racing 5W-30.
