Thanks for the info Former Rotor. So just to make sure I have this straight, normally us diesel fuel doesn't have water. However, the demulsifier in the opti lube may make water present which would then in turn not be a good thing. I do not have a separate apparatus to filter any water like TDIWISE does, so I just want to make sure that I understand fully what may happen with my opti lube usage.
I also read somewhere that our fuel filters have some sort of built in water separator in them with an unknown capacity. I will try and find the link, but is there any truth to this and would it matter? I'm guessing not or you would be using XPD.
Enjoy what you drive.
