Thats what I recently used with high degree of certainty it does work. I drained the fuel tank and poured a 16oz bottle in and ran it for about 10 min. I wish I had ran it longer as is recommended (30min). I didn't notice a difference in performance or idle but when I pulled the plenum this past weekend there were areas on the valves that were VERY clean and other parts that still had carbon buildup. A bottle runs about $12 at Napa and was the best stuff they had.
