R3? Why does Mazda even put 23MPG
 

on the sticker, I've yet to get even 20, and I have done my very best to drive a slow as a granny and still 18mpg is the best it's got. Just turned 4000 miles maybe it still breaking in? I drive 95% hwy everyday... I think they should have just made it more like 16city 18Hwy. Don't get me wrong I love the car but, geez, I hate stopping every 2 days to fill up.

In the US, auto manufactures don't put the car's fuel economy on the sticker. It's controlled and calculated by the EPA.

i left the only accurate answer to the op's question. thread closed
