HondaRD,
I think its probably comparable to Mobil 1, so I'd use the same drain interval you'd run with that oil. The TBN on the spec sheet for this oil is about 10.5, which seems accurate given the additive chemistry. As I recall, Blackstone got a figure of 14.5 for this formulation, which I think is highly doubtful; given the levels of calcium and magnesium in the formulation.
If you are running this in a high revving Honda/Acura engine, I think I'd test it after 6k-7k miles and adjust the change interval accordingly. Running 10k miles in a BMW or Mercedes with a 7.5 to 8.0 quart sump is very different from running 10k miles in a Honda with a 4.0 quart sump.
I'd use my "Oil Change Interval Formula" as a starting point, with the same constant I'd put in for Mobil 1:
OCI(miles) = (80)(average mpg)(sump in quarts)(cubic inches/Hp)
I think that will get you in the ballpark as far as a reasonable change interval ....
