From the owners manual:

5.7L Engine
This engine is designed to meet all emissions regulations and provide satisfactory fuel economy and performance when using high-quality unleaded gasoline having an octane range of 87 to 89. The manufacturer recommends the use of 89 octane for optimum performance. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines.

So, to answer your question directly -- yes.

I doubt the dealer has equipment on hand to test the octane in your tank or the time to do it for that matter. Now e85 is another story is smells very different and is easy to identify. So don't make that mistake.
