Hello Fellow Mercedes 240D & 300D Enthusiasts ! Well, I have replaced most of the front end parts and after all said and done; the most significan difference was noticed when I lowred the tire pressure from 35 psi to 29 psi. My ride have improved consideralbly. I may sacrifice some tire wear; but most of my driving in highway driving. Right now I am getting close to 33 MPG on my 300D (non-turbo) I appreciate all of your assistance and feed back. Safe benzing to you all !! Lovedabch in Virginia Beach, Virginia
