Realistic MPG in 300D's, 300SD's, 190 D's? - Page 4 - PeachParts Mercedes-Benz Forum

In my 300SD my best was 33mpg on the highway. City driving (and I live on a massive hill) it goes down to low teens. It seems I have a knack for getting decent mileage though, pulled 30.7mpg in my 300e this weekend.

The car has LOTS of power for a non turbo (kinda like a gasser), and is very economical. The other 5 cyl's have gotten from 22-25 average every time I have checked. It cracks me up every time I see an ad on CL for a 617 powered car "gets 30 mpg". That is what the gal told me that I got the E300 from, and now I believe her. 30 MPG on a 617 turbo car? I think not...

Yep, later engines just get better mileage if they're in good shape.

My '87 300D gets better mileage than my 240D did (not trying hard, either). I barely managed 32 in the 240D on 100% highway @60 mph, but it was really difficult to duplicate.

I get about 32-35 Combined city n highway. On te highway I go about 60mph, 2,500 rpmn I get about 42 mpg, but if I go about 75-80 mph the rpm goes up to 3,000 n engine gets a little loud, is that something I should worry about ???
Does it hurt my engine???
I'm trying to just to keep the rpm about 2500 n no more.

My 1986 190D has only had a few tankfuls run through it, but the combined city/highway mpg is 34.5 miles per gallon. It's a 2.5 liter normally aspirated engine, with a 5 speed transmission.

83 SD - typically 25-27mpg. I can squeeze 30 with long highway runs.

Many, many, tanks through the car, and I get the above mileage figures very consistently. Awesome car.

Ditto for my '91 300D 2.5, which is now up to 308K.

I get about 30 mpg around town, 35-36 hwy.

With a/c on, I get about 26 mpg around town.

1991 300d, 152k

1986 190D 2.5 na 380,000km 7 L/100km 33.5mpg combined but climb a massive hill every day on the hyway. taking it easy in town. Revs low, speed slow. only really measured one tank though. 100% diesel. Sometimes run diesel wvo mix, mpg drops off a bit. Not measured, just notice less fuel remaining at the end of the week.

anyone got any readings on MPG running 100% WVO?

bustedbenz · #55 10-11-2010, 09:20 AM

My 300SDL gives about 24.5-26.0 mpg no matter how or where I drive it. The 240D frequently comes up with exactly the same range. If anything, the 240 is only 1 mpg (avg) higher. It's really a trivial difference.

I admit I drive like I robbed a bank most of the time. That plays into it.

BSharp · #56 10-11-2010, 10:34 AM

My 87 190DT gets 28 mpg while driving 80% highway @75 mph and using a/c 1/2 the time. The last tank got 30.2 mpg without the a/c. I have yet to test the mpg while driving 100% hwy. FYI, it takes ~1.5 psi of boost to run the a/c at 70 mph.

MaydayMike · #57 10-11-2010, 11:30 AM

I've kept track of my '83 300SD on a spreadsheet for the 40,000 miles that I've owned it. My overall average has been 24.32 mpg. Highest was 27.23, and lowest 21.82. It probably could have been a little better, because most of those miles are in colder weather. I commute on my motorcycle most of the time when it is above 30-40 deg.

JiveTurkey · #58 10-11-2010, 12:15 PM

My '84 300SD averages between 26 and 30 mpg for combined driving. It's a wonderful daily driver.

ssorange · #59 10-11-2010, 07:05 PM

Here are my numbers:

'85 w201 2.2L 39-45
'87 w201 2.5L turbo 30-34
'88 w201 2.5L 34-38

These are over many years of samples. I've throw out the lowest and highest numbers. The turbo gives me the least constant results.

konstan · #60 10-11-2010, 08:30 PM

I get about 27 in my '82 240D around town.
