This was an Indy shop...I'll call the stealership to compare. Yes I can change the oil myself, I do it now on my 04 330ci. I also have the monster 17MM socket
The problem will be resetting the "Service needed" light.
Change every 4,000 miles? Isn't that overkill with synthetic oil? That's whole reason to get synthetic oil is to extend the time needed to replace the oil. I'm sure there are many threads on this debate.
I live near Dinan so let me give them a call and see how much they charge.
