Has to do with these "clean" fuel systems and delivery methods. Newer intermittent injection systems don't seem to respond to the extra lube sort of speak. Talk with your dealer mechanic and see what he has to say and let us know. On my old 12 and 24 valves I did this, same in one of my gravel trucks that has a N14 in it and yes they do seem to smarten them up, not any more than seafoam however. All my older mechanical engines get some seafoam periodically and just before oil changes. The newer trucks and equipment pretty much get left alone. I tried running different makes of fuel conditioners and found my fuel economy actually went down so I just leave it alone now unless I know I'm getting some marginal quality of fuel like from a old tank or remote locations but that's just usually to battle possible water contamination.So whats diffrent now . You still have a pump and Injectors . Some people think it may cause problems with EGR and Particular filters but thats about it .
