I need to know what the gas mileage is on a mazda 6. I am not sure what year. I reserved a rental car and it says it will be a mazda 6 or similar. I am trying to figure out how much i am going to spend on gas on my road trip to fort knox kentucky.
My coworker has a Mazda 6 4cyl. He says he gets mid to upper 30's on the hwy. This is probable if you keep the cruise around 65 or so. You'll probably drop around 2 to 3 mpg for every 5 mph faster.
