Re: [MBZ] om603 MPG estimates?
I just got 24mpg on the last tank in the 300SDL - turbo 603 engine. I have gotten 26 in the past. The last several tanks before this one only got 22MPG, but most starts and acceleration were WOT - kick-down switch engaged.

Re: [MBZ] om603 MPG estimates?
My observations agree with the esteemed Dr. Booth's (although I have a 300D sedan). Subtract 1 or 2 mpg if the weather's hot and you've got the AC on continuously.

Kevin, it's a Euro so it really is a 3 liter turbo diesel, but with the now disable EGR feature.

Re: [MBZ] om603 MPG estimates?
Well, first you have a 602 2.5L anyway, but I get 28-31 most of the time. Lowest was 27 in the mountains (uphill side), highest was 36, but I think that was a fillup error. Normal milage for that car is 32-34. Peter
