Fuel Economy Is In The Eye Of The Beholder!

[Ramius]

Heres a question. 1991 300te24. Nice car, weighs more than some small carribean islands and drives rather well too considering its a little titanic like.

I never expected it to be road runner, never expected it to be as agile as a cat.......

Never expected over 31MPG after cruising at an average of 75 for a distance of 675 miles round trip with 4 kids, a wife and two heavy bags...

Fuel use measured from a full tank and based on till reciepts for literage....

This normal or am I a lucky one???

Hows your car doing?

31mpg cruising at 120kph for a 3 litre petrol engine. But you don't say if you have 5speed manual transmission or 4speed auto. Not sure if 5speed auto was an option that long ago. I think you have 4speed auto from the figure you quote. whilst I have no direct comparison, my figures from 1994 E300D Estate are 90kph = 42mpg / 120kph = 33mpg and I regularly achieve 36 - 37mpg in mixed london / motorway driving. My car has 4speed auto. All said, my gut feeling is that your figure seems reasonable.

I get 28-29 in my 300E, which I again think is a fair return for this type of car.....these figures are achieved at @ 75mph on the motorway.

it really is in the eye of the beholder when you can actually observe the needle moving not so slowly down......1988 300SL...17mpg....

Try lending your son your Range Rover! Then everything falls into perspective.

Pretty normal for a large engined car driven ralatively slowly. I used to get 31-33mpg out of 530i at driven at steady motorway speeds.

What are you doing with it?
I can get 37 out of an E240! (though not round town and not at anything over 70 admittedly). Mercs are always economically crap around town, but then heavy autos are going to be (I used to get 13mpg on the way home from work! - up hill stop start etc) But then I figured that if I was doing 10 miles a day town driving, then fuel economy didn't really matter, and when it does matter (when I'm covering 100's of miles in a short space of time) it comes up to 33-37 which I think is very reasonable for a big V6 bus.

Coasting downhill with a strong tailwind and I reckon I could get up to 30mpg.

In reality I try really, really hard to drive gently and then just have to pop past the car in front and then oh look there's a nice bit of road and then I can just squeeze past that car ahead and try as I might I can't get better than 20 to 24 mpg per fill up. Oh dear.

Must be the econo-meter broken. Anyone know how to fix it? '98 C43.

our SL

has a (lack of) economy meter. Considering it spends most of it's life near or in the red, we sometimes get 27 ish. Usually 22-24 ish, although a couple of weeks ago, 18-ish (curse that seductive kick-down thing.)
strangely magnetic in an optical sense.

Jberks,

You are right. The temptation to go roaring off in a C43 is just too much. Sometimes I find myself doing it just for the noise.........

 

[ash-h]

31mpg in my C32 at 70mph, averaging 20mpg overall.

I get 57.8 mpg in my CLK 270 CDi on my commute to work (45 miles on M1/M25 at around 55mph)
