These cars do that and better every day on EBay.

People seem to love measuring mpg this way, but it's not really a good way to do it. If you fill at the top of the mountain and drive down it for 75 miles and then fill up you'll get REALLY good mileage, but it's not an accurate measure of mpg. If you do the reverse, fill at the bottom then refill at the top you'll get really poor mileage. If you can get 37mpg for a whole tank and over many tanks then you're on to something. You did get 37 mpg, but it's a small portion of the driving you do and doesn't represent the whole picture.

Friend of mine has one since new, and in the days of the 55MPH speed limit, that figure was not out of reach. I doubt it's too doable today with traffic moving at 70-80 MPH.

OM602 or OM603?

602. It's a 190D turbo. I misread the OP.

I'm really confused about fuel mileage. My first MB was a 1976 W115 240D, it consistently got 42-45mpg, which was awesome. I measured a few tankfuls driving very carefully, and other tankfuls flooring the pedal (it was an automatic 240, so that isn't saying much), and it really didn't make much difference at all. I never did much maintenance to the car, just got regular oil changes and fixed necessary problems. It even had working A/C (that I didn't use very often, but the compressor belt was never removed).

Now I've got a 1983 W123 200D, which I bought thinking there would be massively awesome fuel mileage. There's not. I got a pretty consistent 25mpg on all-highway driving when I drove it back from Texas. The injectors were absolute crap (when put on the tester they didn't pop at the appropriate PSI, rather they just started a steady stream at about 50-60% of the appropriate PSI), but I replaced them with ones that tested good (original Bosch, not Monarks yet) and it doesn't appear to have made any difference.

I would really like to know how to get my mpg's up to what I was able to get with the W115. In theory, shouldn't I be able to get even better since it's a 2.0L engine versus 2.4L? I think I get better mileage in my 3.0L's which is just bizarre.

There is a lot that affect mileage. Tire inflation, condition, size, brand, tread patterns, alignment, fuel and air filters, dragging brakes, length of time driving in one sitting, speed of travel, engine temp, wind conditions, hills, differential gear ratios, AC, fuel quality and type, condition of your injectors, valve clearances.

That said your 200D should be getting more, the 240D's usually get in the upper 20's to low 30's so I'd suspect your 200 should be closer to that range I'd be surprised if you can get it into the 40s. I'd start looking through all the things above to make sure everything is in tip top shape. Start with the basic stuff and work into the more complicated stuff.

Mpg for a diesel benz seems like fingerprints on a homo-sapien, they are all different from individual to individual and seem to stay relatively the same from birth to death. My 240d got around 28mpg, wasn't affected by tires, alignment, ride height, injectors, load, weight of my nikes, oil type, fuel type, etc. The worst I figured was 27 mpg with bad injectors, clogged fuel filters, bad alignment, discount tires' cheapest rubbers with a busted outer tie rod, and four full grown men and all of their musical instruments. The best was a hair under 29 with just me and ALL of the above fixed. I haven't figured any numbers with my transplanted engine, but I have a feeling they will be different. It's almost as if some where made on a monday after a full nights rest and a cup of coffee, and had mpg in the 30s. And others where made by workers with a hangover or the flu, or maybe someone sneezed while they were making your injection pump.

That or not everyone on this forum was a math major.

I wish I'd held on to my first '76 240D. I am not pulling legs when I say it regularly got 42-45mpg - I used to write down the mileage and gallons every time I'd buy gas and kept a log book for a long time, and the odometer counted miles accurately too. Every MB diesel I've had since then gets less than 30 I think, though I'm not as anal about keeping track as I used to be.

There's a certain satisfaction that comes from driving a 61x diesel regardless though. The V-8's are fun now and again but are massively overkill for everyday driving. And I can tell you that 12mpg's as I get in my 1974 450SE regardless of driving style is quite depressing!

Well there's your problem right there, you are trying to burn gas in a diesel.
