I got 18.83 mpg on my most recent tankful, and intend to continue using premium. The good thing is each tankful has been getting slighly better. I fill it to where I can see gasoline so I am consistent.

Is that 4wd or 2wd?

I just picked up my FJ 4x4 M/T tonight. Curious to see if you MPG increases as your motor breaks in in. Do you have 16' or 17' rims on yours? Do you have aggressive off road tires?
