ISLAMABAD, October 25, 2026: Rising petrol costs are making fuel efficiency increasingly important for motorists across Pakistan, with experts recommending simple changes in driving habits, vehicle maintenance and journey planning to reduce unnecessary fuel consumption.
From maintaining correct tyre pressure to avoiding aggressive acceleration and excessive idling, several practical measures can help drivers improve their cars’ fuel average without expensive modifications.
With Pakistan also moving towards more frequent fuel price revisions and considering gradual petrol market deregulation in 2027, motorists have additional reasons to monitor how much fuel their vehicles consume.
How to calculate your car’s actual fuel average
Before attempting to improve fuel efficiency, drivers should establish how much petrol their vehicle currently consumes.
One of the simplest methods is the full-tank calculation.
Motorists can fill the fuel tank until the pump nozzle automatically stops, reset the trip meter and drive normally before refilling the tank to the same level.
Dividing the distance travelled by the number of litres required to refill the tank provides the vehicle’s average fuel consumption in kilometres per litre.
For example, a car travelling 420 kilometres on 35 litres of petrol delivers an average of 12 kilometres per litre.
Repeating the calculation over two or three refills provides a more reliable picture because traffic conditions, road types and driving patterns can affect individual readings.
How much money can better fuel efficiency save?
Even a modest improvement in fuel economy can make a noticeable difference to monthly petrol expenses.
Using an illustrative petrol price of Rs364.35 per litre, which was applicable on September 9, 2026, the estimated cost of driving 1,000 kilometres varies considerably depending on a vehicle’s fuel average.
| Fuel average | Petrol consumed | Estimated monthly cost |
|---|---|---|
| 8 km/l | 125 litres | Rs45,544 |
| 10 km/l | 100 litres | Rs36,435 |
| 11 km/l | 90.9 litres | Rs33,123 |
| 12 km/l | 83.3 litres | Rs30,363 |
| 13 km/l | 76.9 litres | Rs28,027 |
| 14 km/l | 71.4 litres | Rs26,025 |
| 15 km/l | 66.7 litres | Rs24,290 |
Improving fuel economy from 10 kilometres per litre to 12 kilometres per litre would reduce the estimated petrol bill by approximately Rs6,073 for every 1,000 kilometres travelled under these assumptions.
These calculations are based on September 2026 fuel prices and should not be confused with current pump rates.
Smooth driving can reduce petrol consumption
Driving behaviour is among the most important factors affecting fuel efficiency.
Sudden acceleration forces the engine to use more fuel, while repeated hard braking wastes energy that has already been used to increase the vehicle’s speed.
Drivers can reduce unnecessary consumption by accelerating gradually, maintaining a safe distance from other vehicles and anticipating traffic signals.
For example, motorists approaching a red light can ease off the accelerator earlier rather than continuing to accelerate before braking sharply.
The objective is not necessarily to drive slowly but to maintain a smoother and more consistent driving pattern.
Maintain sensible motorway speeds
Driving at higher speeds does not automatically improve fuel economy.
As vehicle speed increases, aerodynamic resistance generally rises, requiring the engine to work harder.
The most efficient cruising speed differs between vehicles because of variations in engine design, transmission, weight and aerodynamics.
Motorists should maintain a steady speed within legal limits and avoid unnecessary acceleration during motorway journeys.
Check tyre pressure regularly
Incorrect tyre pressure can increase fuel consumption and affect vehicle handling.
Underinflated tyres create additional rolling resistance, forcing the engine to use more energy.
Drivers should check tyre pressure at least once a month, preferably when the tyres are cold.
The correct pressure is normally specified on a label inside the driver’s door or in the vehicle owner’s manual.
Motorists should avoid inflating tyres beyond the manufacturer’s recommended pressure simply to improve fuel economy.
Wheel alignment should also be inspected if the vehicle pulls to one side or the tyres show uneven wear.
Avoid unnecessary engine idling
Leaving a vehicle’s engine running while parked consumes petrol without covering any distance.
Depending on engine size, air conditioning use and other factors, idling can consume approximately 0.95 to 1.89 litres of fuel per hour.
This can become significant during extended waits outside schools, shops and other locations.
Drivers can reduce unnecessary fuel consumption by switching off the engine during longer parking periods when it is safe and practical.
However, repeatedly switching off the engine in moving traffic is not advisable where it could compromise safety.
Use air conditioning efficiently
Air conditioning places an additional load on a vehicle’s engine, but switching it off completely is not always practical, particularly during Pakistan’s summer months.
Drivers can improve efficiency by allowing trapped hot air to escape from a parked vehicle before switching on the air conditioner.
Opening the doors or windows briefly can help reduce the initial cooling demand.
Once the cabin begins cooling, closing the windows can help the air conditioning system operate effectively.
At motorway speeds, keeping windows widely open can increase aerodynamic drag and may offset some of the fuel savings from reduced air conditioning use.
A poorly functioning air conditioning system should also be inspected rather than continuously operated at maximum cooling.
Regular maintenance helps maintain fuel economy
A mechanically healthy vehicle generally performs more efficiently than one with neglected maintenance.
Drivers experiencing an unexplained decline in fuel average should examine possible mechanical causes before replacing parts unnecessarily.
Important areas include tyre pressure, wheel alignment, brake drag, engine oil, ignition components, air intake, cooling system and transmission performance.
Warning lights, unusual engine behaviour or overdue servicing may also indicate problems affecting fuel consumption.
Motorists should follow the manufacturer’s recommended maintenance schedule and use the specified engine oil grade.
Using thicker oil without a technical reason does not necessarily improve engine performance or fuel economy.
Combine short trips and avoid heavy traffic
Journey planning can also help reduce petrol consumption.
Combining several nearby errands into one trip may reduce unnecessary travel, repeated engine warm-up cycles and time spent in traffic.
Where possible, drivers can use traffic information to identify less congested routes or adjust departure times.
A slightly longer route with smoother traffic may sometimes consume less fuel than a shorter journey involving repeated stops and prolonged idling.
However, the most efficient route depends on actual traffic conditions, distance and vehicle performance.
Remove unnecessary weight from your car
Carrying additional weight increases the energy required to accelerate a vehicle.
Drivers should remove unnecessary items from the boot while retaining essential equipment such as the spare wheel and emergency supplies.
Roof-mounted cargo boxes and other external accessories can also increase aerodynamic resistance, particularly at higher speeds.
Removing unused roof accessories may therefore help improve efficiency during longer journeys.
Does high-octane petrol improve fuel average?
Higher-octane petrol does not automatically deliver better mileage in every vehicle.
Drivers should use the fuel grade recommended or required by their vehicle manufacturer.
Some engines designed for premium petrol may benefit from higher-octane fuel, but vehicles intended to run on regular petrol may not achieve meaningful savings from switching to a more expensive grade.
Motorists should also be cautious about additives, fuel-saving magnets and aftermarket devices promising dramatic improvements in mileage.
Claims of substantial fuel savings should be supported by reliable testing rather than promotional statements.
What to do if your car’s fuel average suddenly drops
A significant decline in fuel economy may indicate changing driving conditions or an underlying mechanical problem.
Before visiting a workshop, drivers should compare their current fuel consumption with previous readings and consider whether traffic, air conditioning use, journey length or driving habits have changed.
They should also check tyre pressure, warning lights, braking performance and recent maintenance work.
For example, a vehicle that consistently delivered 12 kilometres per litre but suddenly drops to eight kilometres per litre under similar driving conditions may require a mechanical inspection.
Identifying the actual cause is generally more effective than replacing components without diagnosis.
Petrol pricing changes make fuel efficiency more important
Pakistan’s fuel pricing system has been undergoing changes, with the Petroleum Division moving towards more frequent price revisions during 2026.
A possible gradual transition towards market-based petrol pricing has also been discussed for June 2027.
Although the final impact of these developments remains uncertain, motorists can reduce their exposure to fuel expenses by improving vehicle efficiency.
For most drivers, the most practical starting points remain straightforward: measure actual fuel consumption, drive smoothly, maintain correct tyre pressure, avoid unnecessary idling and keep the vehicle properly serviced.
These measures can help motorists reduce petrol expenses without relying on costly modifications or unproven fuel-saving products.
