[Little General]

The owners manuel for the 08 does say use prem fuel. If not it could cause spark knock and the such.........The 08 has the 6.2 corvette engine it and it does run better on 93.The only thing that pissed me off is when I bought my 08, the dealer filled it with 87 octane . They suggested 93 to prevent "engine damage" and told me to switch to 93 but they were too cheap to give a full tank of prem.
