I BOUGHT a 2003 Daewoo Kalos auto hatch with 43,000km on the clock from a used-car dealer. In the few months of owning it I have experienced fuel use of 11.0 litres/100km in normal city driving. This is considerably more than the 7.6 litres/100km claimed in the car's specification sheet and defeats the purpose of buying a small, supposedly fuel-efficient car. I have returned the car to the dealer to investigate, only to be told no fault could be found. An internet search revealed several other Kalos owners experiencing high fuel use so I wonder if it could be an issue with the GM E-TEC II engine.

CONTEMPORARY road tests gave the average fuel consumption of the Kalos at 7.5 litres/100km so yours does seem particularly high. First, make sure everything is in order with the engine and emission system. Take it to a mechanic who knows his stuff. Hopefully the dealer is reputable, not simply trying to get rid of you by telling you all is well. Something in the emission system could have failed and is telling the engine's computer to run rich.
