Hey as a fairly newbie to world of FJ's, I bought this vehicle because I thought they were cool as crap since seeing them at an auto show before they were produced in the USA. Loved them for their toughness and go anywhere style. I Didn't buy it for gas mileage and that's a good thing because it Loves fuel. I have seen on YouTube 2 guys that do a modification claiming 25mpg. It insures changing plugs to Denso Iridium (which I used power Iridium) changing air filter to Green (brand name) reusable, and Removing a Screen Filter on opposite side (opposing) of air filter. You have to use a screwdriver to basically Pry screen out and Hocus Pocus you get 25mpg. Anyone ever heard of this?? Is it BS??? I Damn sure don't wanna do something to screw up a good running vehicle.
