Update on the 'Ticking" from my wife's Escape ... it is completely gone! She has about 700 miles on the Valvoline Restore and Protect now and I have a few miles over 800. A friend suggested that since my V6 is a VVT engine, the Valvoline Restore and Protect might very well have cleaned out the oil passages to the VVT solenoids, making them perform back to spec, which likely could explain the improved throttle response.
