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.
