Jim Andersons "Old Wives Tales" in TDR issue 44, I agree with the first part. I disagree with the last.
With or without the reducing of sulfur, I think the use of a fuel system cleaner and lubricant makes things run a lot better. Amsoil's Diesel Fuel Modifier does both, it is cheap to use as 1 oz per 5 gallons of fuel is all that is necessary. It keeps my Cummins running smooth and gives me a little better mileage. It also preseves the life of the fuel pump.
Keeps those injectors clean all the time. I have been using it all the time for many years, and it works as advertised.
