Running 100% WMO in rear 100% Diesel in front tank - question

[mankypro]

What additive should I use in the diesel only tank to help keep things as clean as possible? Diesel Kleen? Acetone? Turpentine?

I just want to wash out my lines, pump & injectors as best possible every time I switch to my diesel tank for shutdown.

Use what ever you want but the oil thats left in the filter will return to the diesel tank when you switch tanks anyway.
Every so often I dump some Dieselkleen in.
