My 240D rolling average is 28mpg over 120,000 miles in 2 cars. The '78 240D gets 28mpg average pretty much no matter what, it'll be interesting to see it go down a bit with bio-diesel and it'll go down to maybe 26mpg if I hold it to 85mph all day but otherwise 28mpg. I got my '83 240D as high as 32mpg at 60mph highway runs. Never had to opportunity to take it a really long distance, I always thought it might have made 35mpg if I could have run it at 60mph for a full tank of fuel.
My '84 190D 2.2l auto will easily do 40mpg if I take it easy, otherwise it averages a solid 38mpg. The newer 60x engines are more efficient, the car is smaller, lighter and has a lower co-efficeient of drag. -Curt Date: Sun, 28 Oct 2012 09:45:34 -0400 From: Michael Canfield <slozuk...@gmail.com> To: Mercedes Discussion List <Mercedes@okiebenz.com> Subject: Re: [MBZ] W123 MPG Message-ID: <calhj_1drdosk1rxf+nweux6aardavrtgrfb-o21gknkep9r...@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 What MPG do you guys that still drive W123 chassis cars get?
