I dont know how it will go with synthetic atf. I might change it next year when i change out my fluid.... If I do I will probably go with redline as their reputation of providing smooth shifting in with thier products.

I am using delvac one in the beast and am happy with it. Most of all it should aid in the ignition of my 300d in the cold chicago winters. I do agree with the authors who state that frequent oil changes are still in order. 3 to 4 thousand seems good. Sure it is expensive but I do not want to rebuild a mercedes diesel. My basic belief is that it is far superior oil and its only money. since I do the work myself I might as well use the highest quality materials. I really like the fact that the oil has not yet lost it protective properties when i change it.... that is the whole idea....It is always protected.


I would probably buy synthetic shampoo if they sold it but I have not found it yet..


thanks for all your help
