Nope.

Think about it. High compression ratio = premium fuel is 1970s thinking. If the LGX or any engine required premium for its rated HP and torque, GM / manufacturer would be legally required to indicate that. It's a different story if premium is recommended, which is NOT the case with the LGX.

Unless you have verified data that supports what you posted about "max wide open throttle", you've fallen for the premium fuel sales pitch.
