The article says: "Sulfur acts as a lubricant in diesel, and by lowering the sulfur content there is a corresponding drop in the fuel's lubricity."
Do we have a source for this? I've heard that this is false: sulfur is just plain bad for fuel. The reason for this myth, I've heard, is that a common mechanism for removing sulfur from petrodiesel also breaks down larger hydrocarbon molecules that provide lubrication. That is, ULSD may have less lubrication, but it's not because sulfur is a lubricant, but because the process of removing the sulfur also broke down some of the fuel's inherent lubrication.
For example, [1] says "The processing required to reduce sulfur to 15 ppm also removes naturally-occurring lubricity agents in diesel fuel."
It is definitely not the sulfur that gives diesel fuel its lubricating properties, it is the cocktail of various polar and aromatic compounds that are taken out as a by-product of reducing the sulfur content. This article explains it pretty well: http://www.marship.eu/loss-of-lubricity-in-diesel-fuel Hildenja ( talk) 13:11, 31 August 2016 (UTC)
I assume Canada has harmonized its standards with the US? What about Mexico? Those buying a new diesel expecting ULSD fuel who travel are curious.
I know at least Canadian standards are the same. Here is an article about it [2]
Canada has curiously decided to label Ultra Low Sulphur Diesel (ULSD) as Low Sulphur Diesel (LSD) or no label at all. There is no requirement to label since all on-highway diesel is supposed to be ULSD. The label consists of a yellow background with a black circle with the words Low Sulphur Diesel around the circumference of the circle. [3]. This apparent misnomer is in direct conflict with the labelling strategy in the USA which is regulated by the EPA. [4]. Generally, Low Sulphur Diesel (LSD) refers to the diesel product that contains <500ppm sulphur. This caused me considerable angst and I had to go to extrodinary steps to try and locate ULSD which is required in my vehicle. In my quest I did find one supplier with the above mentioned yellow label but the words on that label were Ultra Low Sulphur Diesel. In the vicinity of my home most diesel vendors have adopted the green labels specified by the EPA in the USA. This is probably due to the high volume of US travellers in this area.

Will this also affect kerosene? Since many diesel owners cut their fuel with kerosene in winter for easier start up, I thought there may be some problems. Mustang6172 05:06, 17 September 2006 (UTC)
A little clarification: Kerosene designated as no. 1 highway diesel is subject to the same sulfur requirements as no. 2 highway diesel. Kerosene for home heating use is subject to the same sulfur requirements of home heating oil. All distillate (diesel, heating oil, kerosene) is subject to the pump labeling requirements.
Isn't the spelling normally sulfur, especially in North America where this is mostly used? But I guess ULSD could be a British name that kept its spelling. 74.104.224.144 20:55, 3 March 2007 (UTC)
I have flushed out these sections a little, but the sources I found on them were not sufficiently clear (and a bit out of date). I will keep looking but hope that others can also add what information they can find.-- Gregalton 17:23, 11 March 2007 (UTC)
right now this article begins with a very US centric intro then goes on to provide information about sulpher in deisel in general. I therefore propose moving this article to a more general title like sulfur in deisel and then rewriting the intro to be a summary of information from different parts of the world and draw any desired contrasts between them (e.g. the fact that the US jumped from 500 to 15 bypassing the 50 that seems significant in european/european influenced places). The main detailed sections could then remain mostly as they are though possiblly gain a bit more history. Any objections? —The preceding unsigned comment was added by Plugwash ( talk • contribs) 02:02, 1 April 2007 (UTC).
I believe that this article should be condensed and merged into the article on diesel fuel. By 2010, nearly all diesel fuel markets in industrialized nations will have completely moved to Ultra-low Sulfur Diesel (ULSD) fuel or will be well on their way. It doesn't make sense to have an article on ULSD, it is like having a seperate article for unleaded gasoline. I propose renaming the article as "Regulation of Sulfur Content in Diesel Fuel" or something similiar and moving it into the Diesel Fuel article. -- Jcollura 04:34, 10 May 2007 (UTC)
This page seems to have at least some sentences in common with the following Chevron FAQ: http://www.chevron.com/products/prodserv/fuels/diesel/ulsd.shtml

Cyberbot II has detected links on Ultra-low-sulfur diesel which have been added to the blacklist, either globally or locally. Links tend to be blacklisted because they have a history of being spammed or are highly inappropriate for Wikipedia. The addition will be logged at one of these locations: local or global If you believe the specific link should be exempt from the blacklist, you may request that it is white-listed. Alternatively, you may request that the link is removed from or altered on the blacklist locally or globally. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. Please do not remove the tag until the issue is resolved. You may set the invisible parameter to "true" whilst requests to white-list are being processed. Should you require any help with this process, please ask at the help desk.
Below is a list of links that were found on the main page:

Again another article that contains a list of countries, but there isn't information on why exactly one would want to avoid sulphur in their fuel, or what even happens. So I'd argue that the article fails to describe its subject. For instance, the term "sulphur dioxide" is only mentioned once in the Hong Kong section, and the term "NOx adsorber" is missing completely. There is some work to do.
