I'm by no means an expert on the subject, but did do quite a bit of research prior to deciding on 2 cycle tcw3 as the additive of choice for my situation.

From my understanding diesel kleen is primarily a fuel system cleaner. It cleans deposits from injectors and injector pumps (which detroits do not have).

It does appear to have some lubricating qualities but is not the primary purpose of the product.

Generally speaking our old detroits do not suffer from becoming 'dirty' or clogged fuel systems b/c we have 2-3 filters upstream of the engine that seem to handle any junk/gunk that can clog an injector.

While i do not think diesel kleen is bad or shouldn't be used I do not feel it completely addresses the lubricity issues caused by low sulfur fuel.

If you want to use diesel kleen I believe I would use an additional additive for more lubricity.
