Last week I bought a 240D. So I have just used my first tank of fuel. I managed to get 31.5 MPG (That’s UK gallons – 4.55liters). This was with 160 miles being at motorway speeds of between 85 mph and 95mph, with the rest being around town and in traffic.
Is this as good as it gets?
Anything I should do to get better gas mileage?

If you are getting 31.5 mpg's, doing a lot of hyway driving at those speeds you are doing very well. Like always, if you slow down you will get even better fuel mileage.
Also your 240D is around 3300 lbs, not near the 4000 as Lorbenzo says. The larger 300 SD's were in the 3800-4000 lbs.

Actually it works out as 25 MPG in US gallons. We have 4.55 liters and you have 3.78. To be honest I am very heavy footed and struggle to keep my speed down.

The car tends to cruise at an inidcated 75-85 MPH and have had it up to 100mph, which is how fast the speedo goes. I was surprised it got that high considering the book speed is nearer 80mph. Is this abnormal?

Last summer i checked my 240TD and got 33mpg US gallon. Which leaves about 0.72l to 10km.

My 82 300D weights in at about 4500 pounds.

A little off topic.

rrgrassi- your 300D weighs 4500 lbs. ? My 80 300D reg. papers says it weighs 1551 Kg. which is about 3415 lbs. What do your reg. papers say about weight. The 4500 lbs might be the gross vehicle weight ( GVW ) with passengers and luggage. 4500 lbs seems very high.
Can anyone else chime in on some weights of their veh's.

Just curious.

108Benz you are correct, 4500 is the gross vehicle weight, 3400ish is more like kerb weight.

I have had mine up to an indicated 100mph and it felt like there was more. I have heard that that Euro versions had more power due to emmision reasons. I amnot fully aware however it seems to pull real well.

0-60 sucks though. :D

You sure there aren't 5 injectors under the hood then? Or perhaps your speedo is in Km/hr? Does it feel lke your JUST keeping up with traffic, blowing by everyone, or being passed as well? I'm wondering if your dash internals for your speedo are from a gasser or something odd like that? I know that the 240D and the 300D had way different rear ends over the years......

yes, it sounds very strange that a 240 was at 95mph. i mean i'm sure its possible, but very stange. that's as fast as i've been in my 300D.

Everything is standard on the car. No oversized wheels to throw anything off. I am pretty sure it is the 4 banger with no turbo. At 100 mph it felt like 100mph and at 85mph i was slightly faster then traffic which again is about right.

On my 240TD the speedo just keeps going after it has passed the cars max speed. So dont be to sure it works. Check with a GPS ;)

It is a 240d with 3 speed auto. I have not checked it with GPS but it feels right. I am sure the gearing allows for that sort of speed. It was reving very high and was noisy but stable.

On the vehicle weights how do you determine the model you have. I know I have a 123 but what are the other 3 numbers after the . ? eg. 123.125
