Yep - extra money for no benefit. Use castrol syntec edge - if you are consuming oil between changes could try high mileage version of mob 1 - the 5w30 is a good oil ...Works just like most other oils--it'll lubricate the motor and turn black just like all other oils.
Not sure what you're expecting, but you're not going to get a cooler motor, more horsepower, more torque, faster 0-60 times, etc by making the switch.
