I have never read a post with eyes so wide as I did just now. Never knew we could have a tank of algaes in Diesel.
The only info I know of our diesel tanks (in our bus company) is that we have to regularly let the water condensation out - somewhat like a radiator flush - just beneath the tank. Let the little bit of water out, and then tighten it back. Doing this will produce efficient running with less black smoke.
Does diesel MB cars have that function too?
I'm wondering coz I have this feeling I'm looking at a 270E - a diesel. I have some good reviews about that, just don't know the price yet. Reckon it might be cheaper as its rolled of the Siamese plant and covered by the AFTA - i.e. less tariff $$$ for this particular model.
