06 4.2 S/C MPG PROBLEM

Ok then, i'll give you an answer... Yes a service should help the mpg especially if the oil in your motor is really old and seriously mucky, mention the poor mpg at the service dept and they will check over a few things for you. Your air filter for example might be blocked but i'm sure they will inspect it for you.
