Are you comparing the Techron CONCENTRATE to the “fuel system cleaner”?When Techron was a young product, it used to specify on the bottle the aggregate maximum dosage(s) that should be used during a single OCI, and generally suggested it was better to dose before an OC, to mitigate any potential oil dilution issues.
Why that verbiage was removed is a mystery. The only practical explanation is that it's not as potent as it used to be, but that's a WAG.
Two different products.
