posting a bunch of stuff in case anybody is looking for information This suv has the older engine without the cartridge oil filter the change was mid year. Best mileage was 34mpg almost all city below 40mph Typical mileage with AC usage limited highway is 31mpg A lot of highway miles drops it to 28 ish mpg. Note the Goodyear tires are 19 inches and are inflated to 50 psi, if you do your own tire rotation these tires are really heavy. The vehicle is really sensitive to acceleration for mpgs. Blocking off the radiator will be next to impossible. Gerry
