Actually they have added a bunch of additives to combat the lack of sulpher. Now the problem will be to keep your fuel filter changed often for the next while while the deposits break down in your engine from the additional detergents

No need to add fuel conditioners for lubricity, but it's a good idea to run injector cleaners and most of them have lubricity improvers in them.
Just a heads up, sulpher is not a lubricant, it's the process that removes sulpher that lowers lubricants.
Like morkable said, a very good idea to change fuel filters more often until ULSD has been in the pipelines for awhile.

The B20 I had sampled recently showed a HFRR ( High Frequency Recprocating Rig ) lubricity rating of 0.244 which is very good. The new ULSD standard requires a minimum HFRR of 0.520. The lower the HFRR # the better, these are facts, believe what you want.

I use silver PS from Wally Mart. I have also used Lucas with good results on fuel millage. Not sure what product would be a better choice, I think they are both good.

Sulphur in an internal combustion engine has no beneficial qualities, and several undesirable effects.
Refining sulphur out of #2 (so the new diesel particulate filters, catalytic converters and EGR systems won't be damaged) removes the lighter aromatics and reduces it's lubricity. Additives are supposed to be blended in before it can get into your fuel tank, but many don't wish to take a chance - and add their own conditioner.
The absence of some of the lighter aromatics both reduces the energy content of #2 by ~1% and raises it's cetane number a few points.

Actually, it is accurate...

On the other hand, sulphur bearing compounds provide a high pressure lubricant used in extreme applications to raise the seizure point to acceptable levels. Notice I said sulphur BEARING compounds not pure or free sulphur.
The problems start when a heat threshold is reached that promotes the breakdown of the sulphur bearing compounds into less complicated easier to form ones that are corrosive and/or caustic.
In internal combustion engines sulfuric acids are formed that the oil has to netralize.The sulfuric oxides are exhausted into the atmospher where they can recombine into other compounds. In extreme pressure situations sulfuric gasses form that are bad for humans and the equipment.
Just saying sulphur is good or bad is an extremly broad statement that could be right as often as it is wrong.

That's why I keep referencing it's non-lubricative qualities in an internal combustion engine... we're familiar with sulphur-bearing anti-seize and high pressure, high temperature grease.
