It's true that high octane pump gas has a slightly higher concentration of cleaning agents. But having tried both methods, I'm convinced that you're better off buying a bottle of quality fuel injector cleaner once a year.
It's not a matter of cost so much as effectiveness.
For the same $3 spent on a tank of premium gas, you can buy a more effective product.
