I loaded up on Nextgen Maxlife 10W-40 during the FAR exravaganza of 2012. Every auto parts chain offered this, sometimes over a period of months and most had the 10W-40 on clearance, so it was actually cheaper than free after rebate.
The BMW does very well on this oil. It leaks noticeably with the Defy I've tried for the last few changes, but not with Nextgen Maxlife.
I have plenty of the Nexgen Maxlife left so I'll go back to it once I've used the last two jugs of FAR Defy 10W-40 I have.
Nextgen is still offered, I believe, but it seems that most places have had it on clearance for a year or more.
