I would recommend the Redline DFC if you are able to find it. It did make a difference on my 82 240D and have noticed that it idles smoother and less smoke than when I don't use it.

However, I don't use the additive in my 87 300SDL because it has a catalytic converter and there is a red sticker located inside the fuel door the specifically states "diesel only/no additives." I was warned on another post that additives usually contain some metals that will clog the converter with regular I don't use it but my 300SDL idles smooth anyway.
