Driving Techniques to help you save Petrol

Drive within Speed Limit

Your fuel mileage will decrease rapidly when you travel at speeds over 95 km/h.

20% more petrol is consumed when traveling at 110km/h than at 90 km/h.

Remind family members that drive to adhere to this. This will also prevent them from getting traffic summons.

Anticipate Driving Conditions

Use an alternative route if you know the traffic is heavy on a certain road.

This also applies to driving conditions that may cause you to tailgate or practise some other inefficient driving procedures.

The cleaner and smoother that your driving is the more petrol costs you will save. Plan your driving routes accordingly. You’ll save yourself frustration as well as money.

Avoid Peak Timings

In slow traffic, you’ll be wasting petrol and causing wear and tear on your car.

If you are heading home and know that the journey is going to be slow you may want to consider running some errands in the meantime.

Accelerate before going upslope

When approaching upslope, accelerate before you reach it. This will save fuel while you are climbing upslope.

Caution: Accelerate in a safe manner or you wont be able to save fuel ever again.

Employ higher gears

If you drive at fast speeds using the wrong and often lower gears, you will reduce your fuel economy by as much as 40 percent.

Keep foot off Brake when Driving

Try to avoid the habit of keeping your foot on the brake, even lightly, when you are driving. When you rest your foot on the brake you use more fuel than you would otherwise and you also will wear out your brakes much sooner. This brings back to the point that you should drive within the speed limit so as to reduce the frequency of braking.

Buy Environmental Friendly or Smart Cars

Buying a hybrid vehicle can save on the cost of fuel.

Travel Tips

When you are traveling with a carrier or a roof rack, you will be increasing your fuel cost by as much as 5 percent. Reduce the amount of aerodynamic drag and improve your fuel consumption by placing as much as you can in the trunk of your car.

When carrying heavy objects in the car, you reduce your fuel economy by as much as 1 to 2 percent.

It might be more beneficial to hire a truck or borrow one from a friend so that you can reduce the wear and tear on your car as well as keep down your fuel costs.

Tightening the Fuel Cap

It may seem like a small thing to do, but tightening the fuel cap on your car will prevent petrol from evaporating and escaping into the air.

Cruise Control

When you are driving on the highway you should be using cruise control whenever possible to maintain a steady pace.

This will help to increase your fuel consumption.

Many newer vehicles come with cruise control as a feature and not as a luxury choice for just this reason: to save on fuel costs.

How to Save Petrol during Refuelling

Paying attention to little details can save you a lot of petrol in the long run. The routine act of refuelling your machine is one such avenue for you to save petrol.

  • Avoid refueling when your petrol level is lower than half-tank. This is because petrol vapour will escape more readily when the tank is low in fuel. The optimum to refuel is when the fuel reaches 3/4 mark.
  • Refuel during the night or when the temperature is low. When the weather is hot, petrol vapourises more readily to the environment.


  • Furthermore, petrol expands during higher temperature, so you are pumping more fuel but with lower volume when the weather cools down.

In some countries, some drivers actually jerk their vehicles when they refuel. The reason behind it is to fill the tank more fully. However critics had mentioned that cars are engineered in such a way to leave some space within the tank.

Saving Petrol – An Overview

Engine
Ensure that your engine is in proper working condition. This would reduce the fuel required to work the engine. Regular servicing would obtain maximum efficiency for the vehicle. A dirty engine could increase fuel consumption by 10 to 20% while a clogged air filter increases 10% of fuel consumption. The air filter and the fuel filter should be kept clean. Use new filters if required. Installing an oxygen sensor could improve mileage by almost 15%.

Feed multi-grade oil to your engine because it reduces drag. Change the oil regularly. Certain engines work optimally with different kinds or grades of fuel so do refer to the vehicle manual.

Avoid running engine idle for a long time. The engine warms up faster while driving so there is no need to wait for it to warm up before moving off. If your engine uses petrol as fuel than it’s more efficient to turn off the engine than to run it idle for more than 30 sec.

Go for the four-cylinder engine rather than going for V6 or V8. Light cars consume less fuel than large vehicles. Before buying a new vehicle look at its rated efficiency.

Close Windows
Open windows increases resistance to wind flow that increases fuel consumption by as much as 20%.

Grade of Fuel
Fuel tank caps that are either loose, damaged or are not there at all, cause petrol to vaporize. Close the cap properly every time you open it.

Air pressure in tyres

Poorly inflated tyres cause wastage of fuel as well as wear and tear of the tyres. Check your vehicle’s tyre pressures at least once in a month. You can refer to the specified tyre pressure label around the driver seat. Use radial ply tyres instead of cross ply ones because they offer comparatively less rolling resistance and longer life. Ensuring wheel alignments are proper gives 10 percent saving of fuel.

Plan your trip
Try to plan your trips during less-congested times of the day whenever possible. With less traffic, you can maintain a smooth engine running without having to apply harsh brakes. You can use the internet to check out the shortest route to your destination. Never put extra luggage on car’s roof rack as it increases weight. Road and weather conditions also play a major role in the fuel economy of your vehicle. Driving on a plain road can reduce fuel economy by as much as 6 percent. On the contrary on a road with upward slope causes 7 percent loss of fuel. Examine suspension and chassis parts for misalignment such as axles, bad shocks, bent wheels, or broken springs.

Air Conditioning

As vehicle speed increases, air resistance increases in an exponential fashion. While going on long tour try to maintain constant speed it improves fuel efficiency. Use the A/C it when required. With A/C on, an extra load is placed on the engine forcing more fuel to be used by about 20%. Furthermore, the engine runs inefficiently when it’s cold.
