I have decided to have them change the filters now and check the filters in a few months . I will treat the fuel and keep an eye on it and rely on both my filters to do their job. There is an additive called Diesel Tech for boats/algae problems. I have never lost power , chugged or had the check engine light come on . Thanks to all for your responses , the guy at the Cummins center agreed with me .
Good plan. Have the fuel from the filters tested see what you are dealing with. It's a waste of money to buy treatment you don't need.
