To kinda get this thread back on topic, here is a little pet peeve of mine with regards to fuel.

If the minimum octane rating for the Crossfire is 91, why can't I buy it 91 octane anywhere?
Around here all that's available is 87, 89, 93, 94. Isn't 93 and 94 overkill?

And what car requires 89 octane? I've never come across one.

I'll continue to buy 93 octane of course (buying premium gas costs only about $3 more per tank).

I just thought I'd give my little rant.
