Is it true that with the ultra low sulfer fuel one has to add addditives to the fuel? I have a 2005 ford 6.0 and am told that they don't put many additives in the fuel

That is a much debated issue, especially on this forum. Some swear by additives and others swear at them.
The fuel industry claims that sufficient lubricity additives are already put in the fuel. Some older diesel engines have experienced lift pump and injector pump failures while using ULSD, but it can't be positively correlated to the ULSD use. There haven't been enough problems to prove the ULSD was the cause.
I occasionally add OptiLube for several reasons, one being to provide extra lubricity for the fuel system, but that's just my personal choice. It would cost around $20,000 to replace my engine, so it seems reasonble to add something cheap to possibly reduce the risk; although most types of fuel system failures would not destroy the engine unless ignored.

Hate to disagree Marv. But the pump shop I use. Told me that he has seen a big increase in the number of old systems in for repair. Since the low sulphur fuel came out.
Check out the Ford-Entusiast.com forum for info on your 6.0. I have found a ton of info to include all the service procedures. I have a 2004 F350 6.0. I have run diesel clean & motorcraft additives with out seeing any visible results. I now add 2 cyle oil to my diesel and have seen an increase in fuel mileage and a quieter engine. I put about 12 ounces to a tank of fuel(38 gals.).
Lubricity or lack of kills injection pumps, here's a good comparison of additives out there Diesel Additive Study
Particles in fuel kills injectors, stock fuel filters are not good enough. There is a white paper I read that was put out by Boshe, that recomended 2 micron filtering. Water is an instant killer. I upgraded my fuel system so it draws from the tank, then a spin-on 144 micron water filter, then a 3 micron spin-on fuel filter, then the stock 7 micron water blocking fuel filter.

Then it does a good job of lubricating for all solvents. Look at the Diesel Place lubricity additive study results (www.dieselplace.com/forum/showthread.php?t=177728). It is ranked second only to 2% biodiesel and sure beat many of the more popular additives.
Propylene glycol ethers: --> are commonly used as solvents
Xylene: --> xylene refers to a group of three benzene derivatives which are used as a solvent
Cumene --> is used as a thinner for paints,
Naphthalene --> is a natural constituent of coal tar (approximately 11%) (HSBD, 1995). It is present in gasoline and diesel fuels. Naphthalene is used as a moth repellent,
Ethylbenzene --> is an organic chemical compound which is an aromatic hydrocarbon. Its major use is in the petrochemical industry as an intermediate compound for the production of styrene, which in turn is used for making polystyrene, a commonly used plastic material

That's sure different than the one I saw, it showed Stanadyne as one of the top ones for lubricity. I bought some ($25.00 for a 250 gallons). Added it at last fillup but I only drove about 40 miles after that.
