Saving fuel is necessary not only to save money but to
reduce pollution. Here are few important tips to see how we can save fuel and
be happier as we reduce our spending and remain calm while driving.
1. Fuel at night or early morning: This is a phenomenon we
often do not realise. We refuel petrol/diesel when the tank gets to the
reserve. Oil expands with the rise in temperature. This expansion causes lesser
energy generation, if fuelled in hot time of the day. The fuel will burn faster
than what you imagine. Best time to fuel the car is early in the morning or
later at night.
2. Fill fuel when half tank empty: One of the most important
tips is to fill up when your petrol/ diesel tank is HALF FULL. There is a
scientific reason to why you must do this. The more petrol/ diesel you have in
your tank, the less air occupying its empty space. Petrol/ diesel evaporate
faster when in contact with air. Nowadays petrol/diesel storage tanks have an
internal floating roof. This roof serves as zero clearance between the petrol/
diesel and the atmosphere, so it minimises the evaporation.
3. Avoid full throttle while filling fuel: There are three
modes in how you can fuel in a petrol pump. Low, medium and high. If you are
using high throttle (i.e. filling fast, pressing the lever down fully), it can
easily evaporate. So try to fill at a slower speed when you are in a self-service
station, or instruct the bunk attendant.
4. Don’t fuel when the fuel filling tanker is filling the
underground storage: It is important to notice this as when the tankers fill
fuel at the fuel station all the dirt that is settled at the bottom gets
disturbed and if you are fuelling at the same time it can get into your vehicle
tank along with fuel – it can affect your engine.
5. Regular checking of tyre pressure: Tyre pressure must be
checked once every two weeks. It helps to reduce the drag while driving thus
increasing your mileage. There is a label in your car just when you open the
driver seat which tells you the tyre pressure.
I normally keep 1 psi above what is recommended while
driving in city, it gives me better mileage. But when you are driving on
highway, please keep the tyre pressure as recommended by the manufacturer
because the tyre warms up on rotation. If you have greater air pressure, when
the temperature rises, it can expand thus putting more pressure on the tyre. It
can explode if it is a tube tyre or get punctured faster.
6. Clear of unwanted items from the car. We normally forget
or get lazy to clear off the items and keep accumulating things unless we are
falling short of space in the boot. It is important that you remove all the
unwanted items whenever you are starting to move around. Every extra kilo of
weight will need additional fuel, decreasing the mileage.
7. Replace spark plugs: once every 5 years, you must replace
the spark plugs, use a better-quality spark plug not the ordinary one which
comes with the stock car. It improves your fuel combustion thus giving more
mileage and it improves your Air condition performance.
8. Service your car at regular intervals: During car
service, always get three things replaced – oil, oil filter & air filter.
If you can find a reliable mechanic then you can do it at low cost. Only
100-200 rupee if you buy the oil, oil filter & air filter.
