S124 OM606.910 n/a

Recently I have been doing fairly long daily round trips usually between 420 - 500 miles, yesterday was no different brimming the tank in my home town the day before.

Made the trip and started to head back, noticed the fuel tank was still reading over half i tank which i put down to mild weather conditions with little head wind.

I also used a slightly different route with more motorways now the engine/car has bed it, for these reasons I made and allowance plus being a glass half full person wanted to believe the gauge.

Getting closer to home the gauge was sitting on quarter of a tank, no problem should make it with ease which I did, glanced down at the trip counter which rolled over at or around 442.

Today, revered off drive car didn't hesitate to start poodled off down the road, she conked out..checked fuel lines looked to be a fuel issue - gauge still residing just under quarter of tank?

Knocked one of my neigbours to help me get some fuel but battery gave out before she fired, currently on charge - anyhoo..back to the subject title, pulled the MB handbook to calculate mileage per tank, it holds 72 liters including reserve, at 28mpg (per MB handbook) it should return yup,

....442 miles

What is an "S124"? A Diesel W124 should get 500mi/tank hammering it. Fuel filters, or a tank of crap fuel? Or does the W124 tank collapse like a W123 with a clogged vent? Maybe not holding 20+ gallons as it should.
Brimming the tank equals how many gallons after a 500 mile trip?

72 liters is 19 gallons. It could be that the US spec cars have a larger fuel tank (21 gallons?).

I was wondering that as the description of distance was in miles, and the the tank in liters.

That is the way they do it on the "other side of the pond".

R u having a pop at me RG, lol

Tank capacity is quoted in liters but further on the MB manual states mpg, or at least this was the first reference.

Come on guys doesn't take much to work it out, the only thing to watch for is Imperial v US gallons which are different.

It looks like the gauge or float has stuck, guessing this is pretty common on 26 year old cars - may opt to swap out sender next year.

sloride, sorry, missed the first part of your question, from wiki

"The estate cars (chassis designation S124) came in 5- or 7-seat models, the 7-seater having a rear-facing bench seat that folded flush luggage compartment cover and an optional (in the US until 1994) retractable cargo net. To provide a flat loading floor with the seat folded down, the T-model's rear seat squab was mounted about 10 cm (3.9 in) higher than in saloons, robbing rear seat passengers of some head room.[8] The S124 estate continued in production alongside the new W210 until the S210 estate launched more than a year later. A two-door coupé version was also built, with the chassis designation C124".
