Recently I purchased my first Diesel (07 2500HD LBZ). I don't have allot of diesel knowledge, but I understand that an "antigel" is recomended when temps are below freezing. Well, it's cold in NJ this week and I went to the auto parts store to find some antigel. I purchased a bottle of Diesel Kleene with Cetane Boost by Power Service. Is this the right stuff to use? and what is Catane? My truck is stock with only 1000 miles.
