Cars can be expensive vehicles to maintain when it comes to fuel economy. People, in general, shell out a lot of money paying for fuel. An average working person in India would spend anywhere between Rs 2500 to Rs 5000 on fuel for car per month, give or take. Hence, mileage is one of the key factors in selecting a car to be bought.
But how much more could you save if you were just a little bit wiser when it comes to fuel economy? What if you could save Rs. 500/- and take your family out for that movie they've been wanting to see? How, you ask? Did you know that over speeding and over-revving can make you waste fuel by unnecessarily burning it over time? Most of us even tend to neglect that long idling during traffic jams and signals can cause the engine to continue running and waste fuel in the process. Or what about when you brake suddenly at those speed bumps on the road, letting the fuel burn easy?
The below 4 factors related to driving behavior may shed light on the fuel economy of your car:
Long-Idling: Fuel is consumed when the car is idle by allowing your engine to work while your car is stationary. It's true that fuel is lost when a car is re-started, initially. But more fuel is lost while idling than it is when a car is started, even if the car is switched on for a short period of time and stationary. The idle fuel consumption rate for a car varies from 0.6 ltr/hr to 0.7 lt/hr, depending upon the size of the engine. So a monthly idling of 3 hours could lose you Rs. 200 or more. With close to 2.25 crore cars in India, thats a monthly loss of 450 Crores!
Over-speeding: On average, a car's optimal speed is around 80kph-90kph. When the car is over this range, fuel mileage decreases over time. Cars that move at speeds of above 100 kph cause the fuel economy to be 25% less efficient! But how is it that fuel is consumed more when we over-speed? The answer lies in two cases. The first case is increase in air resistance. The engine pushes air around and takes up almost 40% of the car's energy at highway speeds. Air resistance increases exponentially between speeds of 110kph-120kph than it does between 80kph-90kph. The second case is a more generic fact- Engines are designed for specific speeds, temperatures and rpm ranges so driving out of these ranges simply goes against the fundamental design of the engine itself!
Hard-Braking and Acceleration: Accelerating suddenly and braking hard can cause the engine to consume fuel. Speed bumps are a major contributor to that. Hard-braking, accelerating and hard-braking again for consecutive speed bumps means the car consumes fuel a lot faster. It is recommended to cruise in gear over speed bumps rather than shift into neutral, as no fuel is used. The economical band to cruise over bumps is between 15kph-20kph.
Over-Revving: A typical driver runs an average of 3000 rpm on petrol cars and 2500 rpm on diesel cars before shifting into a higher gearThe economical band for petrol cars is between 1500rpm-2500rpm and for diesel cars is between 1300rpm-2000rpm. Maintaining the right gear so that the RPM stays within these bands helps in optimal engine performance and saving fuel.
With so many factors and so little time for us to even consider them practically, one might think that it's neither worth your time nor the effort to monitor these things when you're driving. Well, you don't need to because with today's technology, keeping track of these 4 factors has never been easier!
