Both bottles for comparison.

yes, we're aware of this from the other oil threads. But here in the US, there's massive confusion at this point.

1. In the recent past, we could only purchase TWS from dealers or BMW performance shops.

2. Castrol release Edge line of oil found in auto parts stores. But we continue to buy TWS at dealer/performance shops.

3. Now this, dealers made the switch to Edge. I want to see the label of dealer's Edge bottles. It should say "approved for, Z4M, M3, M5, M6, Z8." something along this line. I have a feeling the off-the-shelf Edge in the US doesn't have the "approval" label.
