ORIGINAL: tomp ...and the 2008 requires Premium fuel! Not really... Gasoline Octane Use premium unleaded gasoline with a posted octane rating of 91 or higher. You can also use regular unleaded gasoline rated at 87 octane or higher, but your vehicle's acceleration could be slightly reduced, and you might notice a slight audible knocking noise, commonly referred to as spark knock. If the octane is less than 87, you might notice a heavy knocking noise when you drive. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If you are using gasoline rated at 87 octane or higher and you hear heavy knocking, the engine needs service. The engine knock sensor will signal any knock that might be induced due to running 87 octane fuel and the computer will retard the timing to compensate. Yes, there will be a slight power reduction, but unless towing or running up and down the rockies, you will not notice much of a difference. At least I didn't when I tested it out.
