I want to get a Blackstone analysis of this RLI Bio-Syn 0w-30 at 7,000 or 7,500 miles, but it's been 9 months now that I've had the Bio-Syn in the car. So should I change the oil now and get the analysis done at the current 6,200 miles. Or should I wait one more month, which will put my mileage between 7,000 and 7,500 miles before getting the analysis? Here are the choices: UOA at 6,200 miles and 9 months OR UOA at 7,200 miles and 10 months.

Great to hear I should wait. But why? Your reason behind the advice to wait would be nice.
Sorry... The engines I have torn apart to replace head gaskets etc. Where the oil was used in the same regards as your situation on a regular basis the engines were clean and no visible wear was seen.

No need to be sorry. I wasn't speaking directly to you, just anyone who suggested I should wait to 7,200 miles and 10 months \:\!
