Were you going downhill with the wind?

My '05 C230K gets very good mileage - never seen it quite this good, but I think I got over 31 going up into the mountains so I certainly don't think your mileage is impossible.

Congratulations!!

2006 C230 6 speed
If i set cruise at 100 Km/H i can get 7.2L per 100KM. Which acording to the online converter is about 32.7MPG


My personal best was 6.9L per 100KM or 34MPG for you Yanks


Over the last 20,000 KM of mixed driving City and Highway i'm at 9L per 100KM or 26.1 MPG


I drive an 06 M272 2.5L V6 6 Speed



Would be nice for others to post MPG to get some idea if i'm getting decent mileage.

2007 E320 CDI Bluetec
IS THIS CHEATING ??

I bought an 07 E320 Bluetec in AUG 2011. Finally got to take a decent drive (420 miles ) 3 weeks ago in trip from Boston suburbs to New York City suburbs and back in same day. Disciplined myself to 63 - 67 mph ... with avg at 65 mph( manual control, no cruise control). Over the day, air temp was ~~ 42 to 52F. Tire pressure was 30.5 psi .. anything higher tries to tear dashboard internals apart.

Got 40.2 mpg = 5.75 liters / 100 km. That was a surprise..

If MB did the smaller ( 2.2 liter ) diesel in C Class, am sure it would get 44 - 45 + mpg..... almost as good a 50 - 52 mpg Toyota Prius on highway, with a lot more fun when the right foot is pushed down.

2007 E320 CDI Bluetec
Think About It

07 Bluetec has 225-15-55 section tires. Wider than my 01 Volvo V-40 wagon with 195-15-65 section.

Above 30.5 psi, the shock load from pressurized tires, via wider foot print . or patch area on the road, allows more energy ( harshness and shock load ) to be developed from bumps in the road sending higher energy> a harsh JOLT into the car. Stuff inside the dashboard does not like this, so I lowered the pressure from 32 - 33 psi down to 30.5. That's better. I figure I found the ideal pressure. The Volvo can go to 36 psi before same thing happens ... smaller tire patch area on the ground.

If you ever ridden in a newer Corvette, or MB with really wide section tires, with shallow side walls, you'll understand this .... that's why Corvettes that are 5+ years old have had a hard life. I had an '04 Corvette ( bought new ) for 4 years. Lots of stuff was loose in the car from really wide section ( and shallow side wall ) tires on rear.

Mine's been averaging ~13.2 mpg over the last 2200+ miles of (mostly) city driving.
It’s been worth every misspent hydrocarbon. :y

'16 E350, gone: '03 c230k
You crack me up Splinter!

'03 c230 here, 255 r/225 f, auto, avg 22 in strictly small town driving and lately only ~28 on the road trips (but making very good time). Best for me on hwy was 33+ mpg with 225's all around. The 6's seem to get as good of gas mileage on the road as my little I4, but I drive it 90% in town so the extra mpg is nice... If I'm really on it around town I might dip slightly below 20mpg. Oh, and I have the powerchip tune.

Best I've done is 7 L / 100Km or 33 MPG.

I average around 12 L / 100Km or 20 MPG in the city.

Mines an M111 BTW.

You gotta get some distance before you can really count it. In 15 miles or so I can make my car read 39-40mpg average.

Well ... This is what I've got. It's not current, few months back but it's nice.
Part of this trip was at at 5l/100km ... highways, hills and tight turns.



This translates to about 43mpg ...

Sounds like my 3.8 litre Holden Berlina in Aus. It averaged 19.1 litres/100Km over the car's life. = 12 miles/USg.

I was not paying for tyres & fuel in those days of course.
