Default CX 9 Spark plug replacement

Hi everybody,
It's been quite a while since I've joined the group and have a few questions about some routine maintainence... I have a 2010 CX9 with 76000 miles. I checked the info screen and get 20.1 Avg MPG. So do you think I need to change the spark plugs. I know it is quite a jop to do this and I am up to doing it but if changing the plugs doesn't make a change in the MPG I am not sure if I want to do it. Another question I have is about changing the anitfreeze.. I checked it with an antifreeze tester and it read okay. All of your comments are helpful thanks.
Mike

its about 2.4hrs time to change plus plugs and gaskets
