The Z using NEO is much quieter at startup while the car running Valvoline ocassionally has a tapping noise at startup and on hard acceleration you ocassionally hear what sounds like ticking between 4-5K rpms. While this is not a controlled study I personally am convinced the NEO is better for the Z. On the next oil change I will convert the Valvoline car to NEO and see if this makes a difference.
