I know about controlling my right leg n stuff... its just ridiculous that a 60 litter tank can only go about 120km.. that is madness man... hell a turbo car also wouldn't be drinking petrol like that... smaller CC not n option... Dad's doesn't like.. doing about 350km on fuel tank is still bearable for me... but 120... take my life better :)

1st things 1st....how come consume so much petrol? try to find any signs of leak. the leak is also very dangerous my frenz..as a small spark means...bye-bye. :(

Merc 124 be it 200, 200E or 220E is known for higher than average fc due to underpowered. but 230E and above should be ok. but 120km using 60 litres is ridiculous. it translates to 1 litre for every 2km. worse than a Boeing 747 (err, joke)

if found no fuel leak, check spark plug and fuel filter. insufficent supply of fuel or electrical spark may lower engine power output and thus causing hinger consumption.
clogged injectors may do the similar thing. throttle body? maybe acclerator cable stuck.

for EFI system, why not go to mercedez dealer with computer tester for diagnosis? the cost maybe slightly higher.. but imagine cars are human..

sometimes our cars want to eat at hotel also maa...everytime eat at mamak stall also boring laa...
