*this is basically going to work 2 miles and back and other chores... Rare trips through the country. A lot of running idle before even moving so I heat the car properly and comfort.

On my recent fill up I was able to travel 340 miles and required 13.5 gallons. Hence, 25.2 mpg. 55% highway / 45% city

My driving is pretty consistent,

98% Highway @ 68-70 MPH

1984 Extremely Well Maintained 300CD Automatic

140 Miles per work day.

410 - 420 Miles between fill ups

26 - 28 MPG

The variable, for the most part, is the head wind driving up out of the desert.

Now that I have my 300 D running well again and after two months of my 65 mile per day commute, I’m getting 25.6 mpg with 20/80 city/highway (75 mph) driving. The range is about 430 miles.

As an aside my 300 SE gets 18.7 mpg with the same driving conditions. It takes 19 gallons of fuel when the reserve light is on and has a range of about 350 miles.

old 1977 300d got 29mpg ave....20/80 city/hwy 405mile from fill up.

1984 300d turbo got about 21mpg same conditions 350 on up from fill up


still have to test the euro 84 non turbo 300d ....after injector and no smoke i will check.

Last fillup:
400-450 km (248-280 miles), 11.4 gallons, 90% city or mountain roads (higher revs)/5% highway, so somewhere between 21.75 and 24.5 miles to the gallon. Once the odometer is 100% functional I will have a more accurate milleage count.

Latest fill-up:

305 miles
13.5 gallons
= 22.59 mpg
60% city / 40% highway

HOWEVER...

It appears from testing my speed against a friend's brand new Jetta that I was actually travelling between 14 and 16% faster than indicated on my speedometer...HENCE...

22.59 mpg x 1.15% (average discrepancy) = 25.98 mpg

On my W123 I average 24-25 mpg with a 50 50 city highway circuit.....I have gotten 30 mpg 3 times on a long highway trip that involves mountains and a few country roads...never had it out on a long trip that was fairly flat...am certain I could top that. This car has 155,000 miles right now.
