Not sure if the OP has E-Torque or not. I have no experience with E-Torque.I have owned six 5.7 Hemi gas motors over the years though. They don't seem to care which octane you use. I run a high octane tank through it every 4th or 5th fill up. Otherwise, I just use 87 octane.
Be sure to read the break-in section in the manual. You do want to take it on the highway and floor the gas pedal at speed to get the RPM's up for break-in purposes.
