Hi. For the last 10 fill-ups, I have found the fuel computer in my '04 GX to be off by 1.4 - 1.6 MPG when calculated by hand using miles driven/gallons used. I asked a friend who also has an '03 GX and he calculated similar results - the fuel computer consistantly reads 1.5 average MPG higher than actual mileage obtained. QUESTION: Can the fuel computer be calibrated to reflect the TRUE MPG? Could yours be doing the same? Try calculating by hand and see what you come up with. Thanks! fritz04
