a 99 Dodge is not the same type of critter as one of these new emission choked common rail motors


the fuel and injection systems are completely different


I buy premium diesel when I can get it , otherwise add Howes or Stanadyne


Optilube is very good , but its not on the shelve in these parts

I have a 97&02 7.3 Powerstroke I do not run Additives in the fuel, only in the winter for gelling. My 05 6.0 since day one has gotten a additive in the fuel and oil. I only have 138,000 miles on the truck but zero issues. I started using Power Service switch to Optilube Now went back to power service.
