High fuel usage
Question : I AM driving a 2001
Proton Saga 1.3 and am having a problem with high fuel consumption of 7.4km/litre.
The car is used weekly for supermarket trips of 10km each time.
What are the faults besides the carburetor ?
There is no emission of white exhaust gas and there are no visible fuel
leakage marks on the floor or smell detected.
If there are no leaks, then you need to do a full tune up which would include :
1. Strip down and reset the carburetor to spec. Be particularly careful about
setting the float heights and adjusting the automatic choke settings. wrong
settings will incur heavy fuel consumption.
2. Check the valve timing and ignition settings. this is another source of
heavy fuel consumption.
3. Check your brakes if they are dragging, particularly the hand brake
Lastly, because your driving time is so short, it is likely that you are
driving most of the way to and from the supermarket on your coke, as the engine
would hardly have warmed up, also contributing to the heavy fuel consumption.
