when I first bought the yaris 09 i got 32-33 MPG, mixed driving around 75-80 MPH. Then I put an AFE dry cold air intake on, inflated my tires to 40 psi and got 33-37 MPG doing 75-80 MPH, I changed my oil to amsoil, 5w30 with high efficiency oil filter and got 37-39.5 MPG, then I changed my transmission fluid to amsoil, and got 42.8 MPG. So I tried to slow it down and let off the accelerator as much as possible, driving between 55-65 MPH and shot up to 48.9 MPG thats with the original tires (88000 miles) just got new Defender 185/60-15 tires on there now and hope my MPG dont drop any, hoping it gets better. My yaris is an AT.
