About 1 cSt difference. Not even... 11.8 vs 12.6. Very little. Why? Are you one of these guy's that needs an oil that is EXACTLY 11.83423233 cSt to improve your wear by 2ppm? Just kidding.

Now, now Buster... (and it must be 12.5956775 cSt--I was pretty sure you knew that)
You are all comparing the wrong viscosity
HT/HS of GC is 3.6 Cp @ 150C
HT/HS of ASL is 3.5 Cp @ 150C
So these are basically the same, as are the VI's:
GC is 179
ASL is 178
As a practical matter, these oils will flow about the same, unless the temps are well below 0F....

Probably a version of Castrol SLX, Longlife II, 0w-30, unless it's still A3/B4 rated. A factory fill on many Vw/Audi engines - both gas and diesel.
It's very easy to check - just do a VOA and look at the vis @ 100C. If it's < 11.0 Cst, it's an ACEA A5/B5 formulation like Mobil 1....
