Hi everyone,
This may remind you of my thread about dirty fuel.
I always had this black slime in my diesel and was convinced that I had filled up with crap and now it was messing up my tank.
Now I have it again, and I can see it when I fill up (a small pool at the fuel nozzle).
With all the anti-diesel fungus I've been pouring in there over the past few weeks, nothing can survive in there anymore.

When I look at it, it's motor oil. But damn it, how did motor oil get into the diesel? It can only have come in via the lift pump.
Or am I wrong and there's an even more common way via the injection pump?
