521 Miles on a tankful
... and here's the good part: It was city mileage! Filled up, 17.6gallons, which is more than the manual says it holds, which comes out to 29.6mpg in the city. Not bad for an OM603. Usually I get around 28mpg, re-aligned it a couple of weeks ago, bad toe-in, seems it helped.

I did 610 one time on my 90 300D 2.5. I think the highway average was around 35mpg.

By driving almost mind numbingly granny like I have seen 28.7 in the city with my SD..........I don't drive like that anymore, I was nearing insanity.
 Sadly....today I filled up and got 19.8.... Amazing how changes in driving habits can affect mileage. Maybe I'll strive for a middle ground.

So then how big should my 300SD tank be? I almost think it's like a 17... the manual says 20+... when it's nearly on 'R' I can only put 15 gallons in... I'm confused...

I hyper miled once
Middle of the night. Interstate only, no other traffic. I didn't touch the brake between two fuel stops - coasted in and out both times - about 2 hours apart.
Never exceeded 60mph and took ~20 seconds to get there. I got 37 mpg. I'm sure it would NOT have been possible to drive like that in normal traffic.

I have been regularly filling up post 500 miles per tank. but only after the 4spd swap. my axles are getting iffy so it might be time to get the 2.47 rear in there and see if I can get a few more miles

...And then there are these crazy idiots like me claiming to get exceptional mileage while simultaneously claiming to drive in a fairly spirited manner.
Last tank, 533 miles. Took a whopping 18.39 gallons to the brim, on level ground before and after. Foam was already eliminated from the equation. Guys, I need to remind you that the EPA sticker for the 300SDL federal was 25 mpg city and 27 mpg highway. I still have the original invoice.

I have a 1992 250D 2.5L (OM602), 5spd, non-turbo (don't want the complication. if it's enough power for Europeans, it's too much power for Americans and Canadians) that I brought from Germany last year (I'm in Canada), like new, 121K KM, and on a recent very twisty and very mountainous trip with my family (Vancouver to Osooyoos, BC) averaged 5.7L/100km, or around 41mpg (235/x=y where x = metric and y = imperial OR vice versa)
This included 100km of city driving. In Germany it took around 6l/100km at 140km/h (not very fast but good fuel use at that speed), so imagine at slower speeds. Supposedly at 90km/h it takes 4.5l/100km which would be amazing. One of these days I'll have try this. They do have better fuel there (tried Poland and Germany, about 6,000km in one month), with which the max speed is about 20-30km/h faster than on Canadian fuel (Mohawk, supposedly the best we have). I found this out when driving my wife to the hospital and it strained above 160km/h. On German or Polish fuel it had no problems at 160km/h, even on old oil and filters. Also noticed, that my car barely had exhaust smell on Polish and German diesel. Can't say that for Canadian diesel. American diesel is probably better. When are we going to get world class diesel on this continent? Last edited by chris1968230110; 10-02-2008 at 03:45 PM.

That's pretty good. The '87 300SDL was rated at 22 city and 23 hwy MPG EPA by my '87 brochure.

not my best....
This is NOT my best mileage and for a reason......I was in a hurry to get to the Texas GTG and in a hurry to get away from it.
Look at Post #5 and #21 Third Texas Mercedes-Benz Get Together-Saturday, July 26th 2008 I've easily gotten over 600 miles without the reserve light coming on and yes, the light works.
