I was wondering what people are getting for gas mileage in their 4runner. I am currently looking at a 2006 with 143,000 miles. I am looking as a primary vehicle for commuting to work between 65 -80 mph at a 80 mile a day commute, and trips to the mountains etc. Using it that way for a year or two then using it as a back up vehicle for winter driving and trips to the mountains. My current vehicle gets 22 - 23 mpg, depending on the head wind. My second question, what has been done to improve the highway mpg? Thanks
