You should have no problem what so ever w/ mid to premium fuel. I would also consider your motor a mid-performance type, don't get me wrong, its a great motor and am impressed @ what GM did to it. But High Performance Engines are seriously modified and fuel type is a concern with those!
As to your no-start issue. Its sounds to me that you may have a starter or starter solenoid issue and further testing may be required, and it needs to be done when the vehicle "acts up" Let us know!
