I use premium gasoline, but in each case I experienced almost dramatic improvement in performance (more responsive, more power, etc) after the use of Techron. The cars are: 2012 Infiniti G37, 2008 BMW 650i, and 1999 Lexus SC300. The BMW and Lexus, both older showed the most improvement.
One downside, gas mileage went down on on the older car, but performance improved the most.
Thoughts? Any insight would be appreciated. Any downside, other than cost (pretty cheap at Costco)?

I believe The new Techron (with plus) wording comes with performance enhancer additive, same like the Amsoil PI.
Therefore during the period of high concentrate of Techron, you will feel your car livelier, and this will be gone once you refill your tank later.
Back to whether the real improvement on fuel system, at the moment I find is depends on your engine age and the typical fuel you used. For new car, typically I would say there is no noticeable improvement, but if your car start burning oil, then the usage Techron/Redline SI-1 will give more noticeable impact from the reduced carbon/reduced compression.
