Just to back up Tiger's suggestion.
Startron is a fuel enzyme treatment that get rid of fungus (algae,
mold, etc.) in your fuel system. It also treats conditions the fuel. I
actually saw a advertisement for it in a boating magazine the other
day talking of its properties for fuel stability when wintering boats.
It also mentioned something that I didn't really think about. It has
the lowest recommended dosing for any fuel treatment. 1oz per 10
gallons. Of course, it also has the highest price (maybe not highest,
but pretty high) per ounce. I got an 8oz bottle for $20 shipped. It
has lasted me somewhere around a month and I still have some left.
Does it work? I can't really tell a major difference in mileage, but
the engine does seem more responsive.
I say try it.

You know what? I remembered like 2 years ago... when I first bought my 95
E300D... I remembered 27 and 35 rating... same for 1996 to 1999 E300D and
TD... but now I see different numbers... much lower... I wondered why and if
there is any conspiracy involved...
My previous owner gave me the original window sticker... don't know if I
still have it... would say 27/35...
