name is cman and am a new diesel owner i have a 06 2500 4wd. question is what is the verdict on synthetic oil vs std. diesel oil ? would like to hear your opinions. thanks cman

 

Go to the TDR website and do a search. They had three very detailed blind
studies on oil. They sent samples to an oil lab in plain bottles. The bottom
line was that unless you live in a very cold climate or work your truck in a way
that produces a lot of constant heat, you don't need synthetic. I still use it
anyway!
