Ford Motorcraft Premium Gold or Mopar 5/150 (Ford or CJD dealership) is the same as Zerex G-05 - matter of fact, Zerex blends it for Ford and CJD.
Heck, they still sell Jeep diesels in Austrailia - just drop by a Jeep dealership - they use the same stuff in Jeep Liberty CRD's - I'm one of the rare breed that has one of the U.S. versions they sold here in 05 and 06.
Bloody convenient, using the same type antifreeze for both the 87 300D and the 05 Jeep CRD.
