off road diesel

[Dargo]

The 500PPM sulfur concentration warning you saw, Dargo, means that using the fuel in any diesel engine built in the year 2007 or later will destroy the catalytic convertor immediately, which will also lead to more expensive engine problems on down the line.

And by the way, Sulfur is NOT a lubricant.

Hey, that's the sticker I saw! And, I didn't say that sulfur is a lubricant. About all I know is that sulfur has an aroma that is not something I'd put behind my ears. Based on the legislation, I'd guess (be nice, I'm only guessing) that sulfur must be a contaminant.

Yeah, sulfur is a contaminant, in fact it is one of the corrosive elements which led to the closure of the BP Prudhoe Bay pipeline......

Oops. Wrong answer. Do not collect $200 dollars!

The corrosion at the Prudhoe transfer lines (not the main pipeline) was due to microbes. They have to add a microbial inhibitor to the oil flow to keep control of this, yet they did not stay on top of it like they should have. That is why Governor Murkowski is ordering an investigation and possible legal action against BP.

Ill take sulfur for 1000 alex.

Answer: According to this widely used online encyclopedia, sulfur is infact a lubricant in diesel fuel.

BZZZZZZZ

What is Wikipedia?

CORRECT!
http://en.wikipedia.org/wiki/Ultra-Low_Sulfur_Diesel

<snip>Sulfur acts as a lubricant in diesel, and by lowering the sulfur content there is a corresponding drop in the fuel's lubricity. This decrease in lubricating ability results in a minor decrease of energy content, about 1%. This decrease in energy content may result in reduced fuel economy. To achieve the sulfur requirements for the new fuel standards, diesel manufacturers include an additive to keep the fuel flowing smoothly, and to prevent engine damage.<snip>





now there are plenty of you i know that love "i read it on the internet so it HAS to be true" but im not one to arue with wikipedia.

So what? Who cares anyway.

Since all current diesel fuel, including ULSD, meets the current ASTM lubricity standard, the amount of sulphur and how it affects lubrication in today's diesel fuel choices is a moot point. Sulphur is not an issue. Additives have been added by the refiners to meet the spec.

Referring back to one of my previous posts in this thread:

Not really, but since 2005 ALL diesel fuel has met the ASTM D975 specification for lubricity. ULSD also meets that specification. Hence, the reduction in sulphur should have no bearing on the lubricity of the fuel used in your vehicle. A non-issue, so to speak.

 

[Iowachild]

I was always under the assumption that sulphur helped lubricity in diesel fuel. I have now been told the problem with LSD and now ULSD is the catalytic process used to remove sulphur inherently lowers the lubricity of the fuel. How I'm not sure as I am rather chemically challenged. However, as I stated in an earlier thread in this forum started by Soundguy, the refinery I work for added a lubricity agent to LSD and increased the amount of the agent added to ULSD. MadReferee asked in that thread if the additive was to meet or exceed the specs. and unfortunately I don't have the answer yet. First I was on vacation for two weeks, now the one fellow I know I can get a straight answer from is on a couple weeks vacation. But I will post a reply when I get the answer.
BTW: Back in my school daze, I learned to spell it sulphur and still have not adapted to sulfur.

Dont know if sulpher "IS" a lubricant or not...but it exhibits the PROPERTIES of a lubricant..especially in high loading applications such as GEAR LUBES and in MACHINING OILS!

 

[SkyPup]

How much sulfur fuel additive do I have to add to my ULSD to keep it safe?

 

[MadReferee]

How much sulfur fuel additive do I have to add to my ULSD to keep it safe?

AH, a trick question. The answer is NONE.

I have already posted several times why that is the answer.

I dont think..??...anyone adds a "SULPHER" additive to their fuel for additional lubrication...if needed...but some DO add an "additive" that helps with additional lubrication.
