Sulphur does NOT add lubricity to the fuel; however, the refining process to remove sulphur also removes lubricity from the fuel.

That's what I read about it anyways...

"Apparently, one source of the trouble is that there are many ways to remove the sulphur content. The cheapest of these involves hydrotreating, a process that removes sulphur by treating it with hydrogen. Unfortunately, hydrogen is highly reactive and also reduces the lubricity, or lubrication properties, of the end-product diesel. Another factor in the equation is the initial content of sulphur in the base crude oil; crude from Alaska tends to be very high sulphur, Venezuelan relatively low, for example. As a result the lubrication properties of the fuel could be different for each oil refinery and can even change as a particular refinery's crude oil sources change."
