Hi all - it's my first diesel requiring DEF and wanted to see what the majority of you are using to refill the reservoirs. Is there any significant difference between BMW branded DEF and the generic stuff you can buy at your local auto parts store? The generic stuff is significantly cheaper...

Any issues long term using the generic?

Thanks!
