gas variety.
I use 91. I would use 93, but very few gas stations have it around me.
I've heard that it does make a difference on how our cars run and I've also heard that it doesn't matter. Most of my friends use 87 gas and have no trouble with their cars.

Octane has always given the wrong impression to most people. Higher octane does not always mean higher performance. Octane controls the burn rate of the gas. Higher octane actually slows the burn rate thus reduces pre ignition or knock. It's a fine line to walk but you actually want to burn the lowest octane (faster burn rate) without detonation or knock. Cars with knock sensors will retard the timing when it senses knock and that basically will reduce performance. I've found it's probably best to go by the manufacturer's recommendations because most cars now days have knock sensors. As long as you don't get any knock and want to save $$$s and don't mind reduced performance burn the low stuff. Knock is your enemy as is running lean. They generally go hand in hand.
I run the highest I can find. In Kansas, It was 91, but now that Im back in TX I can find 93
Another thing often overlooked is WHO you buy it from. I have gotten bad gas 3 times now from Valero. Never ever from Shell or Exxon or Chevron.
