Thats what I like to hear!

yeah baby sounds good from here to ...lol

i just would put 89 in case it starts to even remotely knock

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:

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.
