I don't drive to hard but now consistently getting 19-20mpg as I do mainly highway miles as this is daily driver for me . These injectors are definitely issue as BMW must have fixed in new S63 engine in M5 as you don't hear about these issues from that forum.. Press your service advisor to contact BMW NA as they can do something

My 2010 X5M has beem serviced by two different dealerships, I mentioned this thread to both...one hasn't Kuni BMW hasn't replied and BMW of Portland has a guy named David there who's condescending because I don't trust dealerships and I haven't let them into my wallet.
