So Tatortodd,

What additive would you recommend for say a 2005 Diesel Ford Excursion?

Cummins endorses Power Service additives.

Given that I live in UK, surrounded by almost 5000 Americans, I'd like to be able to give you an answer. However, although I know a lot of Americans, not a single one brought their own diesel-engined vehicles with them - they ALL have gasoline-engined personal transport. BTW, my 2016 Mercedes-Benz E class station wagon gives me around 54mpg on a run, and the SLK250 roadster around 65....

Hard not to like diesel.

There is definitely an issue with US diesel and Bosch fuel pumps. I have a 2011 Chevy 2500 with a duramax diesel, with the shitty CP4 fuel pump. It's a ticking time bomb:

WHAT IS A CP4 PUMP AND WHY DOES IT FAIL?

I use Diesel Kleen + Cetane Boost with every fillup, and cross my fingers. I have just shy of 150k on the odometer, and don't push it too hard these days. Hopefully it will last many more years. Lots of people have retrofitted their trucks with the much more reliable Bosch CP3.

The Jeep/Dodge 3.0 ecoDiesel engines are suffering from low lubricity fuel and its effects on the Bosch high pressure fuel pumps. So much so, it has forced Jeep/Dodge into a recall. As others have stated here, using some kind of additive (like Hot Shots) is their solution, while keeping fingers crossed, until Bosch offers a replacement part. Evidently, the Bosch HPFP works fine in Europe due to their different formulations.

I'm an oil & gas engineer, and know industry standards for the products refined, transported and sold at the pump. ULSD began to be phased in during 2006 and was fully implemented by 2014. 2005 is tough because it'd be whether or not the manufacturer had upgraded all of the fuel system components in preparation for the new ULSD. It's outside my area of expertise.

4MUL8R (i.e. formulator) works for a company that formulates and manufactures petrochemical additives including those that are injected into gasoline and diesel at the loading rack (i.e. where the tanker trucks are filled). I'd listen to his advice.
