Mine is a 3.4 V6 and it gets about 12 mpg.
I've thrown more parts into it that haven't made a difference yet, but I'm an idiot, so I'll keep failing until I don't.
Hey all Ok thanks a lot guys, didn't mean to beat a dead horse just trying to get actual numbers as I was seeing people claiming "24mpg" and all and was wondering what was the deal with my 4runner. Meh just a few extra bucks at the tank but at least I'm still cruising around in 4runner! Beats the wifes golf anyday (puke)! Thanks all for contributing!
