 Bought a 03 4runner SR5 in 2009. It had 74,000 miles on the V6. When I first got the car I was getting about 18.3 mpg which I wasn't impressed with since my dad was getting almost the same in his sequoia. Then I put a K&N filter on it. Last fill up I got 21 mpg mostly city with a little bit of highway. Awesome vehicle besides the sulfur smell that I get sometimes when stepping on the gas.
