Well, here's hoping that one of those post-ULSD additives we're all going to use is a smoke-booster. Wouldn't want to give up asphyxiating little old ladies as I drive over their compact cars! :

Yes soot is high in carbon, duh. What I meant by sulfur=soot was that the sulfur in the fuel when burned causes the soot. ULSD will have greatly reduced soot/smoke output due to having lower sulfur.

Where did you hear that?

I am really done with discussing the ULSD on these boards, no offense to anyone. There is plenty of reading about it for those who are interested out there. CP, sulfur in the fuel is directly related to the amount of pollutants a diesel engine emits, without getting too specific.

I can't wait for ULSD personally, but some may be less excited than I am, and that's fine. I took way too much abuse a while back when trying to point out the benefits ULSD would have, and am tired of being called a treehugger by those who love smoking up the place

The NRDC has an article on sulfur in diesel. The article says

"the sulfur in diesel fuel renders diesel catalysts ineffective and also harms particulate traps and other filtering systems that can remove at least 90 percent or more of diesel's particulate matter emissions".

For the whole article, see:

http://www.nrdc.org/air/transportation/psulfur.asp

The Cummins/Fleetguard filter/catalyst for soot that requires low sulfur to prevent poisoning is at:

These filters may also require a new engine oil that is low ash to eliminate maintance for cleaning ash out of the filter.

Don't be offended Lightman. Most people are resistant to change. Personally, while I'll admit it IS kind of cool to see that smoke coming out the pipes, I'm not a fan of destroying the air my kids and grandkids are going to have to breath later on down the road....or the air I'm gonna have to breath the rest of my life for that matter.

I wouldn't mind giving bio diesel a try, but I don't know squat about it or where to get it. I've never seen it for sale anywhere.

Well you got the right idea Hoss.

Biodiesel is good stuff, as I've posted before, I've run it for a few years with great results. There aren't too many distributors listed on biodiesel.org's list in texas, and not sure where you are in tx. Here's the list... and some may deliver.

Boy oh boy, didn't thaink that this question would stir the pot up so much. Y'all have cleared up any question that I might have had in my mind though. I agree that sulphur reduction IS a good thing overall (and I don't care if you do want to call me a tree hugger ) Kinda surprised that Alpineram hasn't chimed in here since he runs the european diesel in his truck and aside from the price I ahven't seen any gripes from him about the fuel eh!

Thanks guys. :-*

Thanks for the contacts Lightman. I'm in the Dallas area so none of those are near me, but I'll hold onto them anyway. Might be worth checking into.

Hoss,
Here's something that might interest you: http://www.dallascityhall.com/dallas..._biodisel.html
I googled biodiesel+dallas and there it was. Looks like your homeboys are burning quite a bit of the stuff. Good luck

Well I'm a little bit tree hugger and a little bit redneck; I'd love to see our soybean farmers make more money by "growing" our own biodiesel while giving a full moon to those foreign countries that we currently depend on for oil. By the way, dosen't high sulpher emission cause acid rain?

Lightman

I"ve now run two tanks of b5 thru the cummins, can't tell a bit of difference. Glad to know at least a few gallons are giving the number 1 sign to the middle east I've run b20 in my benz in EVERY tank since 2001, smooth as glass at 20%. Giving the cummins a chance to break in before upping the mix, although some forum members run b50 in their 3rd gen cummins with great results!

Yes, it appears to. Based on my own research as a grad student in the mid-1980s, correlation of low rainwater pH to sulphate ion concentration was quite strong (r^2=0.777 with 1.0 being a "perfect" correlation). The correlation of low rainwater pH to nitrate ion concentration was rather weak (r^2=0.4), another reason why I don't think NOx emissions (the most troublesome for diesels) are the "root of all environmental evil" as we have been led to believe.

Hehe, will comment now ;D
Over here fuel lubricity is regulated. We do have the ultra low sulphur and ultra low ash fuel and oil over here. Actually that stuff works. Pricing is not that bad, the reason for the crazy prices over here is that about 75% of the price on the pump is one tax or another. There is enough evidence that a better quality fuel will enable the producers of engines to make better engines. The mentioned BMW330 is called the ECO-M over here because due to the massive torque it is a bit faster on the circuit than the M-series with the 295hp gasser. A 320D has won the 24hrs of LeMans. Biodiesel is good stuff if it's made properly- over here the quality control on bio is very lax. I did run on 100% bio for about 12k miles- no problem if you have the lift pump to support it and a clean fuel filter. Only downside was that I had 8% less fuel mileage, but this was offset by 11% lower price. I had to reduce timing a bit because of the high cetane rate. Personally I do not see the necessity for smoke out of the exhaust- my goals in bombing are acceleration and mountain driving.
Since our eastern neighbour countries do have higer sulphur fuel we can easily see the effects on lots of trucks (No Dodge, but Iveco Tector with the ISB)- at least with the Austrian norms the lifetimes of the VP44 are higher with the low sulphur stuff. There is much less smoke with the Austrian Diesel and there is slightly more performance.
I think that sulphur reducion in itself is neutral, but a better quality of the fuel is beneficial. Adding a percentage of Biodiesel (rapeseed methyl esther) showed benefits in the longevity of fuel system components. Lots of oil companies here use the RME to offset the loss of lubricity by the cheaper desulfurizing process.

Just my 2c
