We bought a 2006 rav4 from a friend last summer and I want to do a few mods to get closer to 30 mpg. It has the 4 cylinder and is 4wd. I'm thinking about a belly pan, wheel arch filler(the bristle stuff), and maybe a partial boat tail that mounts in the hitch. I keep the tires at 45 psi, and I just replaced all the fluids with synthetic and the mileage came up to about 25 mpg. I replaced the struts and put new shocks/coils in the rear. I used the 3rd row coils to help with payload/towing. Has anyone done a coolant temp or trans temp mod to help with warmup mpg?
