9 months ago it was $12.25 list and I paid $11.64 with BMW club discount at my dealer.
Castrol is starting to market what I believe is a similar line of oil in the US as "Edge." It's not available in 10W-60 in the US yet, though: http://www.castrol.com/castrol/secti...tentId=7067053
But, it is available in Europe:http://www.castrol.com/castrol/produ...tentId=7027067
We can only hope they decide to sell it here.
Edit: Just picked up a couple liters @ $11.25 with club discount ($12.50 list)
