W124 diesel mpg

[reflexboy]

A friend has an E300 diesel saloon W124. Any forum members with the same car? What sort of mpg do you get in town and on a run?*

35 in town, 45 on a run. Hope this helps

Not owned anymore, but around the 30 to 40 range driven fairly hard, and you do have to use the revs on the multivalve to make good progress.

WOW! Those are impressive figures, I'm guessing Lizzy must be pushing you along?
My own, much less impressive stats are 35mpg at a steady 80mph, 30mpg at 90mph (obviously not in this country). No difference which fuel I'm burning either, I've never bettered those in 80k miles. I didn't buy the car for it's fuel efficiency though so I'm not too upset.

I don't believe that 45 mpg is possible in real life, honestly. I think 40 mpg is about the max you'd expect and that would involve driving at 55 mph, with mid 30s at 70 mph and about 30 mpg on short/in town trips.

Really-is this with your car as I see you have a 250?

 

[Simon21]

The fuel consumption graph in the handbook for my 250TD suggests that 45 mpg would be achieved at about 95 kmh, which is 60 mph.

The fuel consumption figures published by Mercedes for the 250 diesel are very similar to the 300 - less than 10% difference. When I can get my scanner out I'll put up the pages.

I'm a bit confused here. I see you have a W124, but your profile says it's a 250TD. I thought the only uk W124 diesels were non turbo?

The T on a 124 series means it's an estate not a turbo.

 

[reflexboy]

Ah, I see. I thought the estates were TE. Oh, so a TE is a petrol estate and a TD is a diesel estate right?

Well done that man.

 

[Richard Elliot]

TD = diesel estate
TDT = turbo diesel estate
TE = Einspritz(injection =petrol) estate

My 12 valve (pre E) will do 45mpg MAX, 37-40 mpg in normal gentle use. Don't expect CDi type economy. My 270CDi which has 60bhp more will do about 5mpg more driven similarly.

Recently bought a E300 multivalve, I got 43mpg on a sedate 110 mile trip home, which i was very pleased with.

It's dependent on gearbox. Autos use more fuel

My old 250TD Auto did 33-34 and every E300 Diesel Auto I've owned did 33 mpg average. The estates are geared a little lower, I believe, so they will use a tad more fuel

I am told they can be quite economical on a long trip if you cruise at 60 mph

49 MPG (believe it or not)

My '94 C220 diesel does 49MPG on our regular 250 mile weekend run.
It doesn't like to go over 60mph mind

 

[Michael_Dinwiddy]

I have an E300 turbo diesel and I get about 450 a tankful that's about £80.
Don't rag it much but when I do fuel consumption goes down about 10%.

Fuel Consumption

Did a trip from Ireland to UK last week - a mixture of our third world standard Irish rural roads, Irish and UK motorways and a day touring around Derbyshire in a 1994 w124 Multivalve diesel automatic.
Speed on Motorways was up to 115 km/hr (approx 70 MPH). Total mileage covered 795 miles, total fuel used 80 litres. That equates to those still using old money as 45 MPG. Very happy with the result and what an excellent long distance tourer.

The figures suggested by mercedes are easily beatable in my opinion - my w124 e220 says it will do 34mpg at a steady 100km/h but in tank to tank conditions I've nudged over 40mpg (doing a near constant 95km/h but obviously stopping/slowing for bends/traffic too and the odd bit of waiting at traffic lights).

Seems manufacturers were more "honest" back then when the emissions/fuel consumption wasn't such a big selling/tax point!

I'd bet an e300 diesel could acheive 45mpg if kept under the speed limit and out of traffic.

I suppose I average around 32/33mpg in my 1990 300d,most of the time the auto box is in 4th and the rev counter is just nudging between 3 and 4k rpm .

The actual mileage per gallon is well over double that because I make biodiesel at a all in cost of just under £3 a gallon as opposed to the £6.70 ish it is at the forecourts.

I buy the veg oil already cleaned up and de watered which makes the job a lot easier but does up the cost of producing each gallon.

Ironically I worry more about having put enough in the tank before leaving house to cover any long distance drives,I do not want to be visiting the forecourts.

The hardest part is the lost evenings making the stuff.

You'll be cruising at 100-110mph then??
