Fuel Efficiency
What is the best method to
measure the fuel efficiency of my car?
The recommended way to measure fuel efficiency ("fuel
average") is to first fill petrol to reach the full
tank level, next note down odometer reading (kilometres)
at that point. After driving for a week top up petrol
to reach full tank and note down the odometer reading
once again. The difference in the two odometer readings
divided by the quantity of fuel needed to top up the tank
the second time will give you the exact fuel efficiency.
For example- If the difference in two
odometer readings is 357 kilometres and the fuel quantity
used for topping up fuel the second time is 21 litres,
then the "average" is 17 kmpl.
You can do a similar calculation over a shorter drive
too, but the reading may be skewed by traffic conditions
on that day.
Remember to use full-tank to full-tank readings only.
Otherwise you would get an approximate figure only. Also
try to average such readings over a long time, say a few
months, rather than relying on a single reading to exactly
know the fuel efficiency of your car.
How do I get better mileage from my Maruti?
The mileage of the vehicle depends on various factors
-
 |
Frequent stopping and short distance
travel consumes more fuel. |
|
Traffic conditions - The mileage
will vary between heavily crowded areas and less
traffic areas. |
|
Needless idling at traffic lights
affect fuel consumption. A mere ten minutes idling
will waste 100cc of fuel. |
|
Tyre pressure - Recommended tyre
pressure should be maintained. The tyre pressure
should be checked preferably in the morning, before
the day heats up. You can find the recommended pressure
for your car in the sticker pasted on Fr. RHS door
and in the owners manual. Less tyre pressure will
increase fuel consumption. |
|
Driving at higher speed consumes
more fuel than driving at steady speed of 45 to
55 kmphr in top gear. |
|
Changing of gears - 1st to 2nd @10
Kmph,2nd to 3rd@20 Kmph,3rd to 4th@30 Kmph. |
|
Adulterated or less quantity of fuel
dispensed by petrol pumps would indicate poor fuel
efficiency. |
|
Clogged air filter, worn out clutch,
badly tuned engine and high pollution levels increase
fuel consumption. |
Even after adhering to the above factors if the fuel consumption
is high, kindly take the vehicle to any of the authorized
Maruti dealer for inspection and fuel consumption testing.
How do I check for purity of fuel and quantity?
There is a test procedure available to check the purity
of fuel. Put a few drops of petrol on blotting paper and
allow the fuel to evaporate. If it does not leave any
mark on blotting paper it means the petrol is not adulterated,
otherwise it is adulterated.
For fuel measurement you should know the fuel tank capacity
of your car. When it is empty fill it up OR get the petrol
in a measuring flask (1or 2 liter capacity).
