Using Low Sulfur Diesel in 2008 6.4 Engine

[alby]

What would be the impact of using "Low Sulfur Diesel" in your new 2008 Super Duty 6.4/engine?

I ask because I've only found 2 stations that I can pump Diesel from that are recommended by Ford for the 2008. One is a Citgo station that has the Ultra Low Sulfur Diesel. The other is a Liberty Station that has B5-Biodiesel.

So I need to know, what harm can be caused if I run a few hundred miles and several fillups on just Low Sulfur Diesel 500ppm? What will happen? Because I can't be tied to my local area stations until 2010 when ULSD is mandated everywhere.

im not 100% what would happen but if something did happen Ford would not warranty your engine... they are designed to run on ULSD

ULSD is almost everywhere around here - can't even get LSD anymore...

BUT - I definately WOULDN'T run LSD in the '08's cause like Raul said, they are DESIGNED to run on ULSD

Don't do it. We used LSD in ours when it was new. In 2 weeks the truck ran horribly. It constantly went into regen and had less power. It smoked like a train (which was nice to see). The reason we were running the fuel was because the dealer told us all stations in our area had ULSD but hadn't changed the decals on the pumps yet. They said by law these stations had to have the new diesel. We took the truck to the dealer to see what was wrong with it and they finally discovered the problem being due to the LSD. I verified that with the station owner. 75% of all stations near my home are only selling LSD with almost none selling ULSD where we work. It really is a pain finding fuel.

Ford guys here said you would probably get a few tank fulls threw before doing serious damage to the engine that won't be covered under warranty.

I was told by a Ford diesel tech that it would damage the injectors.

Boy I sure wish that I could find some 500ppm.

This ULSD has robbed me of power and milage.

i have a stock 96er and live a few miles north of San Francisco. i have yet to notice any loss of power, but i did lose mileage for a few months, then the mpg's went back up to "normal".

Wow, around here in Florida you can't find LSD, just the new ULSD. I would just like to try some of the LSD in my 7.3 just to see what it does. I keep hearing about power and mileage loss, but I have nothing to compare the new stuff to.

I bought my truck after the change and want to see how it would react... wanted to try it when I was in AZ, but couldn't find a pump! (although I KNOW there are some out there)
