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. |
