Considering a 2005 6.0. Anybody know if the 6.0 can tolerate the new low sulfur diesel fuel. Any particular fuel additive helpful?

 

Diesel Kleen I have used it for around 20,000 miles now.

 

The emissions system will probably tolerate the ULSD better than it did the prior fuel.
One frequently refered to "study", claims many popular additives to be worse than using nothing when it comes to fuel lubricity, which is the one property supposedly to have taken a hit from the sulfer reduction.
