Rising petrol/ diesel prices in India: Top 5 tips to increase your car's fuel efficiency

India is witnessing its worst ever heatwave and fuel prices reaching sky high, the commoners are facing a double whammy. High temperatures mean travelling in two-wheeler becomes difficult, while high fuel prices mean a burden on the pocket. While buying an electric vehicle is an option, not everyone can own one, given the high initial ownership cost. For those of us who don't own an electric vehicle, making the best use of our fuel tanks will be a priority, be it petrol or diesel or even CNG. Here are some ways you can make your vehicle go the extra mile.

Use a smaller, lighter car

There are a number of things you can do to reduce your fuel use. The obvious one is to not use your car, but walk or grab your bicycle, if possible. If you do have to drive, try to minimise your total travel distance. One way would be to combine a number of errands into your journey and optimise your route. The specific vehicle you use also matters. As a general rule of thumb, the larger and heavier your car, the more energy and fuel it will require per kilometre.

Choosing a smaller car, rather than a large SUV, will definitely reduce your fuel bill. A large SUV will use almost twice as much fuel per kilometre as a small car. Research also suggests that for every 100kg increase in vehicle weight, fuel consumption increases by about 5% to 7% for a medium-sized car. So in addition to driving a smaller car, it's best to reduce your load and avoid driving around with extra weight.

Use eco-driving techniques

The way you drive is important too. Eco-driving involves being conscious of your fuel consumption and taking actions to reduce it. There are various ways to do this. Every time you brake and stop, you have to accelerate again to reach your desired speed. Acceleration uses a lot of energy and fuel, so driving smoothly, anticipating traffic and preventing stops will lead to savings on your fuel bill.

What you want to do is flow with the traffic and keep your distance from other vehicles. It also helps to keep an eye further up the road, so you can avoid obstacles and therefore unnecessary braking and acceleration. If you're in the minority of people who own a manual vehicle, drive in the highest gear possible to reduce engine load and fuel use. And if you're in an automatic vehicle, use the "eco" setting if you have one.

Give your engine and climate a break

Another simple tip is stop unnecessary idling with the engine still engaged. A small car typically uses one litre of fuel per hour while idling, whereas this is close to two litres per hour for a large SUV. Of course, we idle regularly while waiting in traffic and generally can't do much about that, other than trying to drive outside peak hours when roads are less congested. In other cases, we can change things. For instance, idling when a vehicle is parked will use up fuel unnecessarily. In simple terms, switch off your car when waiting for traffic light to go green, or buy a car with idle start/ stop function.

Turn off the AC

Most people may not realise this, but using your air conditioner can use up quite a bit of extra fuel: somewhere between 4% and 8% of total fuel use. Using the fan instead will require less energy than air conditioning. Or even better, wind down the windows for a bit for fresh air when you are driving in the city. However, this won't be possible in current heatwave conditions of Delhi-NCR and elsewhere. So decide wisely!

Keep your tyres inflated

It also pays to keep your tyres inflated, which can save you between 2% and 4% in fuel use. Under pressure tyres consume more fuel to run and hence, reduces the efficiency. These days, one can check tyre pressure at fuel pumps, so it's recommended to get your tyre pressure checked when you are going for refuelling. Also, your car is designed to be aerodynamically efficient. Anything that changes that, including roof racks, bull bars and bike racks, will come with an additional fuel penalty, particularly at higher speeds, such as on the freeway.
