There's not much to report on overall, but no news is good news in this case. 4,000 miles has turned into 5,000 miles now on everything with no issues. They've been easy miles, but I've still put the car through its paces and in a variety of different situations in that time. She continues to be a damn near perfect daily driver in its current state.
Blackstone Labs just emailed me the latest report of the sample that I sent them. This is the second time I've used their services, and I think I'll start using it from here forward just to keep an eye on things. It brings the cost of an oil change up to around $100 each, but worth it in my opinion to keep a close eye on things.
I'd be interested to see someone with an N54 that had an unhealthy engine and what those numbers looks like. This sample was used for 3,500 miles and was the first I'd sent in while being single turbo. Everything seems to be in proper order, which is always a welcomed sight.
