I just bought an 06 LE and am picking it up in a couple of days. What's everyone using for 87 or 91 octane gas?

87, from whoever has the best price

I always use 87, usually a major brand.

I use regular per owner's manual. I tried premium, didn't see any differrent in performance. Save your money.

I actually use the middle grade. My hubby said to use reg. and when I did he noticed the difference. So I switched back to 89octane.

There is an improvement with 89, but anything more is wasting your money.

The ECU will adjust a little to mid grade, but it is mapped to run on 87, so you will not see a gain from 91+.

I ran my 14.9's with about an even mix of 89 QT gas, and 87 Exxon.

It does seem to run better with the 89 QT though.

I just stay with 87 ... this thing seems to have enough power as is. Don't see the need to try anything else.
