Getting maximum fuel efficiency, thereby pushing up your mileage per litre, is a prime concern for petrol car owners. With rising petrol prices, getting more value out of each tankful has become critical. Read on to learn practical techniques and answers on how to increase mileage of petrol car.

What is a Car Mileage?

Mileage or fuel efficiency indicates how many kilometres your petrol car can travel on a single litre. It is measured in kilometres per litre (kmpl).

A higher mileage reflects the greater distance possible on a petrol tank, leading to fewer refuelling stops and cost savings.

How To Calculate Your Car's Mileage Correctly?

Follow these steps to determine precise real-world mileage:

1. Fill the petrol tank and note the current odometer reading.
2. After driving for a while, refill the tank before it turns nearly empty.
3. Record number of litres filled to top-up petrol tank.
4. Note the updated odometer reading after refuelling.
5. Use the formula: Mileage = Total Distance Covered ÷ Fuel Quantity Filled

Understanding the Factors Affecting Petrol Car Mileage

Harsh acceleration, inconsistent speeds, and improper gear shift increase fuel consumption and lower mileage. Intelligent driving techniques focused on maximising efficiency are essential. Proper maintenance keeps components working optimally, reducing friction losses and improving mileage.

Making some changes in driving style can dramatically improve mileage. Sudden starts and abrupt braking make the engine work extra hard using more petrol. Smooth and progressive acceleration and slowing down consume significantly less fuel.

Fuel-Efficient Driving Practices

This section covers critical techniques for driving fuel efficiently in petrol cars -

Smooth Acceleration and Braking -

Sudden acceleration, where the throttle is pressed hard, causes the engine to rev rapidly to meet the power demand. Lower gears have to be slotted in quickly, resulting in higher RPMs. More fuel and air are injected into cylinders, leading to reduced efficiency.

Similarly, during last-minute hard braking near traffic signals or stop signs, the vehicle's kinetic energy is wasted as heat without being translated into mileage, which causes extra fuel usage.

Optimal Speed and Cruise Control -

Every engine has a speed range that offers the best trade-off between power delivery and minimum specific fuel consumption. Depending on displacement, most petrol engines' speed ranges between 50 and 80 Kmph.

Driving below 40 kmph causes engine operation issues, leading to droplets in efficiency. Beyond 80 km, the exponential rise in wind drag and tyre friction requires disproportionately more engine power output, requiring extra fuel usage.

Top Tips to Increase Mileage

Follow these handy tips to improve your car's fuel economy:

• Drive smoothly without sudden acceleration/braking: Avoid aggressive starts and stops. Smooth driving reduces fuel usage by up to 15%.
• Monitor tyre inflation weekly: Under-inflated tyres increase friction, compromising mileage. Check pressure weekly.
• Service cars regularly, including tune-ups: Well-tuned engines and systems improve combustion efficiency and maximise mileage.
• Limit AC usage to conserve petrol: Use AC judiciously. Reduces engine load, improving fuel economy marginally.

Vehicle Maintenance Tips

Maintaining your petrol car and driving habits are vital to enhancing mileage. The following are some aspects to focus on if you want to understand how to improve mileage of petrol car -

• Tyre Maintenance

Underinflated tyres increase contact friction with the road surface, making it challenging to rotate freely. The engine needs to work harder, using extra fuel, to keep the vehicle moving.

As the manufacturer recommends, maintaining correct tyre pressure ensures the least road resistance. This allows more effortless movement, improving fuel efficiency.

• Engine Health and Air Filters

Efficient fuel burn and exhaust heat dissipation happen only when the engine is finely tuned and running smoothly. This optimal combustion improves mileage.

Replacing clogged air filters is also critical for proper airflow, preventing incomplete fuel combustion that wastes petrol. Hence, periodic tune-ups, oil changes, and replacing filters on schedule help maximise mileage.

Fuel Efficiency Technologies and Features

Turbocharging, variable valve timing, direct injection, and cylinder deactivation are cutting-edge technologies that enhance engine performance and efficiency.

The car body's shape, dimensions and contours directly impact air resistance. Streamlined designs with lowered aerodynamic drag cut through the air using less energy, enhancing mileage.

Choosing the Right Petrol Car for Maximum Mileage

These are the primary considerations if you want to know how to increase average of petrol car -

• Engine Capacity & Cylinders: Petrol cars with lower engine displacements of under 1.2L are more efficient, and 3-cylinder engines have less friction.
• Transmission: A manual transmission is 10-15% more efficient than an automatic gearbox. Better gear control aids the economy.

Conclusion

Adopting fuel-efficient driving techniques, proactive vehicle maintenance procedures, and incorporating technology upgrades can help unlock significant mileage gains in your petrol car.
