can you digress a little on your reasons?...I am totally ignorant on the subject and only have internet resources for information...
I did find this:
Diesel Engines - What will Sea Foam do for my diesel engine? - Sea Foam
Adding Sea Foam to your diesel fuel tank provides the following benefits:
Adds lubricity to the fuel, protecting moving parts from excessive friction damage
Controls moisture in diesel fuel
De-gels frozen diesel fuel
Cleans fuel residues from your fuel system components
Sea Foam cleans the fuel pump and lubricates the O-rings
Sea Foam cleans the pintle valve in your injectors and restores the injector痴 spray pattern (this is where all the power and smoothness comes from in a diesel.)
Cleans carbon deposits from the combustion chamber
Stabilizes diesel fuel up to 2 years (at average 1 ounce Sea Foam /gallon diesel)
All fuels leave a residue in the system that collect contaminants and hinder proper operation of that system. Sea Foam helps keep the system operating properly by making those residues dissolve gently back into a liquid state, allowing those contaminants to be filtered out of the fuel system.
