89 Octane

Gas savings are minimal, especially now. The savings between grades is even less, especially considering you can actually get better mileage on higher octane fuel.
I've never understood why people insist on saving $2/tank to buy the cheap stuff. I go round and round with my wife on this...the Xterra gets 19mpg on high grade, and 16mpg with low grade. That's 19% more efficiency for less than 13% more cost. This happens because the low grade junk sets off the factory knock sensor, and the ECU pulls back timing. You will be doing this by hand with your economy "tune".
Also remember that bent rods aren't cheap either.

No, gas won't be back up to $4/gal anytime soon, the price per barrel is at almost a record low and the economy won't support higher prices. I am a gas snob and only put Shell or Chevron in my vehicles, even in my Jeep. It might cost more, but I do see slightly improved mpg with the better gas. My dad used to tell me that years ago and I thought he was full of it, but I put it to the test and he was right!

Stick with high octane, stick with name brands.
Be aware that the same truck that fills up the "Dave's SunMart" 89 tank then drives across the street to fill up the Chevron 89 tank.
High grade is usually a proprietary blend brought in on a seperate truck. Mid grade is a mix of the two.
To me this is one of those cheap things you should always do to take care of your car...like frequent oil changes, reading and changing spark plugs, and air filter cleaning/replacement. Sure spark plugs can last 2-3yrs, but for $8 I change mine atleast every six months, and I generally get great mileage to make up for it, as well as added performance and knowing what my motor is doing.
Run high grade, run the brand names with detergents, don't look back.
