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 had a 2002 Dodge Cummins that was a tank and relatively trouble free. I have a VW TDI now and run Power Service or Stanadyne in every tank. If a fuel pump grenades due to lack of lubricity, it's many thousands of $ fix.
