I posted this some time ago, but thought I'd re-post. It's from a Chevy based site, the website (dieselplace.com) has a contributor named Ted White,
I'm not sure if he's a mechanic, engineer, or what, but he does seem to know what he's talking about. He has published a lot of information on the
LSD vs ULSD subject. You can do a search for his name and read the info. Here's a summary from one of his posts:
| Quote: | If you search my posts back into 2007 you will see that I have contributed extensive information about the effects, or lack thereof, of lsd on the
emissions system and/or engine.
In order to avoid posting pages and pages of data all over again, the bottom line is, the reason using lsd in our trucks is illegal is because using
lsd produces unacceptable levels of sulfur particulate emissions. It has ALMOST NOTHING to do with whether or not the engine and DPF/DOC will be able
to handle the higher sulfur fuel.
Again, if you search my posts, you will find the links to scientific testing done by the manufacturers which show that there has to be continuous use
of lsd fuel for more than 40,000 miles before any measurable drop in performance of the emissions system occurs. You would have to use it for more
than 100,000 continuous miles to reduce the effective life of the DPF.
I have been keeping track of more than a dozen 2007.5 and newer trucks in Mexico since mid 2007, some of which return to the USA and Canada each
summer, and some of which stay in Mexico, where the fuel is still mostly lsd. Not a single truck has had a day of problems due to fuel, and I
have yet to find a single failure of a DPF reported on this forum
In other words, if you happen to be using lsd fuel occasionally, it is NOT going to cause problems for the engine or emissions system. However, if you
use it continuously, you can expect white smoke emissions during regeneration as sulfur compound are burned out of the DPF. |
I have an '08 Duramax that's been using exclusively Low Sulfur Diesel (No ULSD) in BCS for over a year now. Don't see white smoke during re-gen yet,
but only have 15,000 BCS miles on it so far. I'm not going to loose any sleep over it though.

why...
remember big tanks get condensation in them so you NEED a water separator
and you need to replace it often
just more things to go wrong
and the weight
~8 pounds a gallon
diesel is heavy
more weight = less performance
and more replacement parts incl tires which are EXPENSIVE

Just an option for BajaGuy....
Any fuel tank can get condensation if not kept full. The best thing you can do to eliminate condensation is keep your fuel tank full and eliminate the
air void.
I'm not sure if the Dodge's come with a fuel/water seperator or not, but it is always a good idea to run one if possible - especially in Baja.
As far as weight, 400-450 pounds of fuel isn't a concern in a 3/4 or 1 ton pickup truck. Many trucks actually ride a little better with a little
weight in them. Besides, the only weight you would really adding would be the additional fuel that is in addition to the stock fuel tank capacity
(maybe 200-250 pounds). Or, I guess this could equate to carrying an additional "well fed" passenger!
