87 Octane is recommended for all engines.

You think they would test for engine knock with 87 octane. It wouldn't make any sense to test an engine and recommend an octane rating that would be possible damaging to the engine.

This is copy/pasted right from the 2007 Calibers Owners Manual (page 232):

1.8L/2.0L/2.4L Engines:
Your vehicle is designed to meet all emission regulations and provide excellent fuel economy when using high quality regular unleaded gasoline with an octane rating of 87.

The use of premium gasoline is not recommended. The use of premium gasoline will provide no benefit over high quality regular gasolines, and in some circumstances, may result in poorer performance.

As stated, you're going to be doing just fine with 87. I use 91, personally, only because the price has come down a little. I avoid 93 since I don't have to use it anymore (I had to with my '98 Neon, it had a MPP) and I don't want to be the guinea pig to see how the World engine likes 93.

You'll be peachy with 87. :)
