Is it beneficial? No, not really. I mean it will dilute the old oil and help it run out, but it won't really clean anything.
I say do the AutoRx clean at best, or just a relative short (1000 miles or less) interval with a good conventional oil, let it drain for a good while while really hot - then in with the synthetic oil for not a not too extended OCI.
How many miles? What Kinda car?
