I think I'm going to start off with what BrocLuno recommended with running BG 109 for 15,000 miles at 5,000 mile intervals and also run the Chevron Delo 400 15w40.
I absolutely second using the Chevron Delo 400 15w-40.
For your filter, I would recommend using a Wix 51085 (or 51515 if you have room) if you're planning on a 5,000 to 7,500 mile OCI.
