There might be a issue, have you cleared it recently? If it still acts up, have the dealership take a look at it. You are still under warranty.

Because it is the "current," or instantaneous, MPG. It is exactly what it says it is. Every time you give it a little more, or a little less gas, your current MPG changes. Are you getting that confused with your "Average MPG?"

What you're seeing is just one of four functions of the trip computer. You switch between current fuel mpg, average mpg, estimated distance on remaining fuel, and average speed by pressing the INFO button on the steering wheel.

Yeah, what the previous two people said. Those were both excellnt answers. If you're still confused, read the owners manual that came with your Mazda.
