I would have to look again but I remember reading in the owners manual not to add any fuel additive. I also had a guy tell me he worked for a dealer in 2000. And he said, they were have problems with some engines then because of fuel additive. I know the Hemi was not around in 2000.
So is it safe to run fuel additive? I don't see how it could mess anything up or void the warranty.

 

I've poured a bottle of Carb/Fuel Injector cleaner every 3000 miles or so in every vehicle I've owned since I got my first one 25 years ago. I've had afew for well over 100,000 miles and one company vehicle which had over 235,000 miles put on it in thefive and a halfyears I operated the business, with no ill effects.

 

AMSOIL P.i. Performance Improver Concentrate (API)

AMSOIL P.i. improved fuel economy by reducing port fuel injector deposits, intake valve deposits and combustion chamber deposits in 100% of the vehicles tested!

It helped mine.

I use FP-60 almost every tank full....it's good stuff. It's a cleaner for the fuel systemand a lube for the fuel pump.. http://www.lcdinc.com/fuel.htm

 

Ya I use the carb/injection cleaner also and almost everyone I know that has a diesel uses it religiously.

 

I have used seafoam for years with no harm. I am going to try the Amsoil to see if it is any better. It won't hurt your engine or fuel system.
