Reducing the fuel consumption of your vehicle
Every car owner wants their vehicle to consume less fuel. This can vary depending on the vehicle engine and weight. But there are some ways to keep your fuel economy under control and prevent your vehicle from consuming more fuel than wanted.
Firstly, the most neglected part of a vehicle is its tyre pressure, and this has a massive impact on the vehicles fuel economy.
Tyres should be inflated exactly how the manufacturer advises. On most cars, a small sticker is located on the passenger or drivers side pillar/door.
Correctly inflated tyres will save you money on fuel, but it will also save you money in having to purchase new tyres. Because incorrect tyre pressure will damage your tyre sidewalls.
The US Environmental Protection Agency argues that the correct tyre pressure will “improve your gas mileage by 0.6% on average and up to 3% in some cases.” Additionally, under-inflated tyres “can lower fuel efficiency by about 2%.”
Yes, the way you drive your vehicle has a massive impact on fuel economy. I believe every driver already knows or speculates this.
What do I mean by driving habits?
Well, if you’re the type of driver that accelerates aggressively at each green light or accelerating harshly often, it will increase your fuel consumption drastically.
To add to the point, breaking aggressively will increase the resistance and therefore, your fuel consumption.
Overall, you should avoid accelerating and braking constantly, use your judgment and anticipate the traffic ahead so you don’t need to accelerate or brake aggressively.
Use engine braking
This point relates to what I described above. To stop using your breaks so often. I advise using engine braking.
Engine braking refers to sifting down a gear. When using engine breaking the wheels power the engine and your fuel injectors will shut off, meaning your fuel consumption will be 0.001 l/100km. (99mpg)
Engine braking can be used when going downhill, before a corner and even shifting down through the gears before a traffic light or other intersection.
If you have an automatic transmission, there is nothing you can do, but, let the gearbox do its work.
This technic will not only save you money on fuel, but it will lower the wear on your brake pads.
Mass Air Flow Sensor.
The Mass Air Flow sensor is located just after the air filter cover and before the intake manifold. It’s one of the most important parts of a fuel-injected car.
It works by sending airflow measurement to the vehicle Electronic Control Unit (ECU). If the Mass sensor reading is bad, it could send the wrong voltage to the ECU, therefore, more fuel could be used by the engine then needed.
Some symptoms of a bad Mass Air Flow sensor are loss of power when accelerating, rough idle, Check Engine light, black exhaust smoke etc.
Carbon deposits is the process of burning fuel and the build-up that occurs during this process in the combustion chamber, intake valves, injectors and pistons.
Carbon deposits in your vehicle’s engine are more common in diesel engines but petrol engines are not exempt from this, carbon builds up still occur.
Deposits in the combustion chamber can absorb fuel and not allow it to burn as it should. In a diesel-powered vehicle, the EGR can get clocked which can decrees your fuel economy.
It is important to use engine and injectors cleaner once in a while to make sure certain engine components run at their best.
If you can’t buy a hybrid car, your first question should be, ‘What is the fuel economy of this car?’
