How to Increase Car Mileage- Fuel economy is a concern for most car owners, particularly with increasing fuel costs and the need to conserve the environment. Whether you own a petrol car or a diesel car, maximizing car mileage can save you money and lower emissions. Most drivers are curious how to get good mileage in a car or how to increase mileage of a petrol car, and happily, there are a number of effective methods of doing so.
In this guide, we’ll explore the best techniques to increase car mileage and improve car gas mileage without compromising performance. how to increase mileage of petrol car

1. Drive Smoothly and Avoid Aggressive Driving
One of the easiest ways to improve car mileage is by adopting smooth driving habits. Sudden acceleration, hard braking, and aggressive driving increase fuel consumption significantly. Instead, follow these practices:
- Gradually accelerate and do not make sudden bursts of speed.
- Drive at a constant speed, particularly on highways.
- Practice engine braking rather than depending too much on the brakes.
- Look ahead to traffic lights and slow down progressively rather than braking hard.
Smooth driving can improve car mileage by as much as 30%.
2. Optimize Tire Pressure
Underinflated tires produce more rolling resistance, requiring the engine to work harder and burn more fuel. Always maintain your tires in the correct pressure by doing the following:
- Check tire pressure at least monthly.
- Fill tires to the manufacturer’s recommended PSI level (located in the owner’s manual or driver-side door frame).
- Do not overinflate, as this can cause uneven tire wear and less grip.
Well-inflated tires can increase car gas mileage by 3-5% and make the car safer.
3. Use the Right Engine Oil
The right grade of engine oil is important for fuel efficiency. The wrong oil will increase friction, and the engine will use more fuel. Always:
- Employ engine oil as recommended by the manufacturer.
- Employ synthetic oils that minimize friction and enhance engine performance.
- Change oil on a regular basis to ensure the performance of the engine.
Proper oiling can enhance car mileage by 1-2%.
4. Reduce Unnecessary Weight
A heavier vehicle needs more fuel to travel. Most drivers unconsciously have extra weight in their vehicles, which lowers car gas mileage. To maximize fuel efficiency:
- Take out unnecessary items from the trunk and backseat.
- Don’t use roof racks unless absolutely necessary, as they cause aerodynamic drag.
- Drive light whenever possible, particularly on long road trips.
Shedding that extra weight makes car mileage better up to 5%.
5. Maintain Your Vehicle Properly
Proper maintenance keeps your car running like a top. A neglected vehicle can use up to 10-20% more fuel. Here’s your to-do list:
- Have regular tune-ups of the engine.
- Change dirty air filters so that there will be proper flow of air.
- Keep fuel injectors clean to provide better combustion.
- Maintain spark plugs in proper condition for maximum performance.
A well-maintained engine uses fuel more effectively, assisting you in boosting car mileage.
6. Don’t Idle Excessively
Idling is a waste of fuel. If you’re waiting for over a minute, it’s best to switch off the engine. New engines don’t require long warm-up periods, so:
- Turn off the engine at traffic lights if the stop is longer than a minute.
- Avoid warming up the car for too long before driving.
- Use the start-stop feature if your car has one.
Reducing idling can improve car gas mileage and save fuel. How to Increase Car Mileage
7. Use Air Conditioning Wisely
Air conditioning creates additional load for the engine and increases fuel intake. To avoid wastage of fuel through AC:
- Apply AC only where necessary.
- Keep it moderately cool rather than the lowest.
- Switch to the vehicle’s ventilation at lower speeds.
- Leave the vehicle under shade to reduce cooling requirement.
Smart AC use can enhance car mileage by 5-10%.

8. Drive at Optimal Speeds
High speeds boost aerodynamic drag and fuel usage. All cars have a range of speeds where they burn the least fuel, usually around 50-70 km/h. To boost car mileage:
- Don’t drive too fast on highways. How to Increase Car Mileage
- Employ cruise control on long trips to keep a constant speed.
- Drive in higher gears whenever possible to minimize engine load.
Keeping your speed at an optimal level can increase car gas mileage by as much as 15%.
9. Plan Your Routes Efficiently
Unnecessary stops, traffic jams, and longer routes can burn fuel. To maximize your driving:
- Utilize GPS or navigation software to access the shortest and most free routes.
- Try to avoid rush hour if at all possible.
- Group several errands into a single trip rather than making several short trips.
Effective route planning aids in obtaining good mileage on a car.
10. Utilize Good-Quality Fuel
Low-grade or contaminated fuel can lower engine efficiency and raise fuel consumption. Always:
- Refuel at well-known fuel stations to get high-quality fuel.
- Use premium fuels if so advised by the manufacturer.
- Apply fuel additives if required to clean the engine.
Good fuel quality guarantees smooth engine operation and improved car mileage.
