First of all, I do agree, we should support Parts Shop by buying from them. However, if this is not expedient enough for you, or for what ever other reason you may have to "get it now". Go to redline's website,
http://www.redlineoil.com" for a list of dealers in your area.
Also, if you can't get Diesel Fuel Catalyst, you can use 85 Plus. In a converstaion with one of their chemists, I was told that the two products are actually identical. The only reason that they are sold with different lables on the bottle is out of an interest in maintaining the old customer base that has used DFC for years.
My car has had a 1/2 bottle added to the fuel every time it has been refueled for the past 10 years.
Although I am interested in checking out Lubro Moly...
