Do you seafoam your engine?

mazda 3
I have a 2010 Mazda 3 sport 2.5L, got it brand new with 2 miles on it. I just turned 115k miles and I was just wondering if you guys tend to seafoam into the vacuum lines ever? I know there is theory that it will rid of carbon deposits, but just wondering the thoughts on this? My engine has always ran like a champ and have never replaced any part on the car so far. Still getting about 450 miles to a tank of gas as well. Thanks.
