    Well, I went to where I thought I could get 93, but they did not have it. I filled up with 91 and will be driving easy on this tank.

    Thanks to all who replied! Hopefully no damage was done and this simple change will correct the problems.

    As I was researching octane booster/higher octane gas threads, I found this:

    "a full tank of piss water 91 octane at $2.35/gallon"..... what I wouldn't give to pay that price again!!!!!!!!!

    91 Octane is fine. 93 is of course better but as we mentioned before, just don't use anything less than 91 and your solid.

    Octane boosters only add about a tenth of a point of octane anyway so they're pretty much useless.

    Carfax is only worthwhile if it DOES show something. If it shows nothing, it doesn't mean the car is "clean." I had a Porsche I did $30k in damage to when I was younger and more stupid and the car still had a clean carfax.

I would fill the car with 93 IMMEDIATELY, then pull the battery leads and step on the brakes for 10 seconds. Then reconnect the battery leads. Your ECU should relearn the new fuel curve quickly.
    Even without disconnecting the leads the car will learn the new fuel pretty quickly, though the more aggressive you drive (which you don't really want to do), the faster it learns. Once you burn through this tank of gas you'll be fine. In fact if you filled up 3/4 wit 91 and had 87 in there you're effective octane is probably still about 90 which is a little low but WAY better than 87!

    What do you mean by "best gas"?

    The standard octane in CO is 91. I've lived here over 4 years and I don't think I've ever seen more than 91 anywhere other than the track or some isolated stations where you can get ~100 octane.

    The car requires "premium" fuel and 91 octane qualifies as premium. There's absolutely no need to look for 93.
