That's a great suggestion, thank you. This weekend I hope to start tackling some of these projects. I'll post pictures when I'm there.

From what I have seen through out the forum, potential is there between hypermiling and a full aerodynamic make over to double the stock mpg. Every little bit helps.

Apologies in advance for dredging up an old thread...

...but 35mpg is doable in a 300SD. I usually run between 25 and 30mpg, but I have on a couple occasions hit 35 mpg.
