9 Ways to Improve Fuel Efficiency of Your Car

Key Points

  1. Smallest changes in your driving habits can make a big difference on improving your car fuel efficiency.
  2. Always plan your journey to avoid unnecessary traffic issues.
  3. Driving safe and steady is always the best way to avoid unnecessary fuel consumption.

Have you ever considered how much of an impact your driving habits have on the fuel efficiency of your car? With the rising price of fuel in Malaysia, it is more important than ever to think about how you are driving and if your vehicle can improve its fuel efficiency.

Sometimes the smallest changes can make a big difference. You may be interested to know that you can improve your fuel efficiency with 9 simple steps.

Reduce Weights

The more weight you take on, the less enjoyable driving can be. Get rid of anything that is unnecessary and takes up space in your car. You’ll be surprised that the car is heavier when you add up either a forgotten backpack or sports equipment in your car.

Interesting fact
Did you know every extra 50kg your car puts on will increase fuel consumption by 2%?

Remain Steady When Accelerating

I remember the first time when I learned how to drive, my instructor wanted me to drive safe and steady, especially when accelerating. Not only are you safer, but decrease fuel consumption.

When you’re driving a car and need to accelerate quickly, don’t rev the accelerator all of sudden. Prevent sudden acceleration or hard brake as this will help conserve fuel.

Regular Maintenance

Maintaining your car is the number one way to prevent rolling resistance from taking away fuel efficiency. Make sure you check for any loose parts and inflate tires appropriately so they don’t wear down too quickly. When you drive a car with underinflated tires, it will increase fuel consumption by 3%, and this will cost you a fortune for a long period of time.

Moreover, your engine’s efficiency is a key factor in determining how much fuel you use. That means anything that affects it, such as dirty spark plugs and air filters or clogged up injection systems, will have an effect on your overall gas consumption! Therefore regular maintenance is a must if you want to improve your fuel efficiency for your car.

If yours is a used car, you might need to put more effort and care into your engine status, because your car might be old enough to have engine issues. Read here to know more about the differences between new and used cars.

Be Prepared For Your Journey

It is important to plan your journey before you start driving. If possible, try to avoid traffic black spots as well as busy times. Consider using the navigation apps (Google Map, Waze) to help you with your road journey. This will not only allow your journey to go smoothly, but also improve fuel efficiency.

Moreover, combine your journey and run your errands one after the other in that particular area, to avoid multiple visits to the same place. For example, if you plan to visit your friend at KL Gateway, you should also visit Jaya Grocer to purchase any groceries before going home (if necessary).

The consequences of stop-start traffic are easily seen, especially when most of us now are working at the office. According to road safety expert Professor Dr Kulanthayan K.C. Mani, there are 33.3 million registered vehicles in Malaysia, much higher than the total number of Malaysians (32.6 million) last year. With the increasing pressure on the engine and greater consumption of fuel usage drastically reduces the fuel efficiency of a car.


The Eco Mode is designed to give you better fuel economy by restricting engine and transmission performance.

When you stomp on the gas, your vehicle won’t do everything in its power to go as fast it can. Instead of going at top speed which would be against manufacturer guidelines for Eco Mode settings, it’ll travel only at the speed allowed with those settings activated.

Drive Within Speed Limit

Depending on the route, it is recommended to drive at a stable speed that is not too fast nor too slow. Speeding up fast and braking hard can be very fuel inefficient, so avoid doing that when driving on the highway.

The efficiency of a car changes depending on how fast you’re going. For example, at 120 km per hour, your vehicle uses about 20% more fuel than when traveling slower speeds at 100km/h. The ideal speed to avoid fuel waste and maximize your driving efficiency is about 50-90 km/h on the highway.

Avoid Idling In Your Vehicle

Sometimes I would like to sit in my car with air cond and music to enjoy some alone time, especially after a busy day. However, this is not a good way to improve your fuel efficiency. We might have a misconception that idling cars will not waste much fuel in the process.

Surprisingly, idling your car is a huge waste of fuel and gives off tons more pollution compared to when you are driving. So, next time when you are waiting for something or someone that requires more than 3 minutes, turn off your engine. It might seem like a small action but can make an incredible difference in how much fuel is used!

Understand The Road

We have different kinds of roads in Malaysia, from flat surfaces to uphill and downhill kinds of road. It is important to understand so that you can choose the most efficient way to drive on that road.

For example, when going uphill, you should accelerate early and use gravity to your advantage by building up momentum when going down the incline to help you get uphill easily. This will help you gain speed, rather than accelerating hard up the hill.

When driving, look far ahead and try to keep moving wherever possible by anticipating obstacles. Easing off the accelerator is better than speeding up then braking again, it’s more efficient!

Choose The Right Fuel

There are misconceptions about using RON97 is more efficient than RON95. However, this is wrong, because RON97 not only cost more than RON95, and it didn’t reduce any fuel consumption. Not only is your fuel efficiency not improving, it might increase the burden of your daily financial planning. Read here to understand which fuel is more suitable for you!


As we know, driving nowadays in Malaysia is NOT cheap at all. Therefore, improving the fuel efficiency of your car is a must! Reduce weight, regular maintenance of your car is very important. Moreover, your driving behavior is one of the main factors to improve the fuel efficiency for your car! Therefore, DO drive safe and steady!
