I have this exact same problem in my 300E, but with mine it seems like the gas mileage changes alot. Some days i get pretty good gas mileage, and others (most) its horrible.
Sounds like my story..
When i bought the car i got about 18-20 mile/gallon. Then suddenly i would sometimes only get 10, driving the same route every day?
It went up and down for a month or two, and now it has settled on "ridiculous low gas milage".
-I could buy a decent used car every month for the money i'm spending on gas!
