How to Calculate Your Driving Fuel Costs
Calculating your driving fuel costs is simple once you know the formula. Take the total distance of your trip and divide it by your vehicle's fuel economy (how many kilometres it travels per litre). This gives you the total litres of fuel needed. Multiply that by the current price per litre and you have your total trip cost.
For example, a 400 KM trip in a car that averages 14 KM/L with petrol at PKR 270/L would require about 28.6 litres of fuel, costing roughly PKR 7,720. If you're travelling with 4 passengers, the cost per person drops to just under PKR 1,930 — making carpooling significantly cheaper.
Practical Tips to Improve Your Vehicle's Fuel Efficiency
- •Maintain proper tire pressure — Under-inflated tyres can reduce fuel economy by up to 3%. Check pressure at least once a month.
- •Avoid sudden acceleration and hard braking — Aggressive driving can lower fuel economy by 15–30% on highways and up to 40% in stop-and-go traffic.
- •Remove excess weight from the vehicle — Every extra 50 kg in your car can reduce fuel efficiency by around 1–2%. Clear out the trunk.
- •Stick to regular engine tuning — Replace spark plugs, change engine oil, and clean air filters on schedule for peak efficiency.
- •Drive at moderate, steady speeds — Use cruise control on highways and avoid unnecessary idling for longer than 30 seconds.
Frequently Asked Questions (FAQ)
How to Calculate Your Trip Cost
The formula is straightforward: divide your total trip distance (in kilometres) by your vehicle's fuel average (KM per litre) to get the total litres of fuel required. Then multiply that by the current fuel price per litre to get the estimated trip cost. For example, a 300 KM trip in a sedan averaging 13 KM/L with petrol at PKR 270/L would need about 23 litres, costing roughly PKR 6,230. Planning a trip abroad?

| Vehicle Type | Average (KM/L) |
|---|---|
| Small Car (Alto, Mehran) | 15 – 18 |
| Sedan (Civic, Corolla) | 12 – 14 |
| SUV (Fortuner, Sportage) | 8 – 10 |
| Motorcycle (70cc–150cc) | 40 – 50 |
3 Tips to Improve Fuel Efficiency
Maintain Proper Tire Pressure — Under-inflated tyres increase rolling resistance, forcing your engine to work harder and burn more fuel. Check pressure at least once a month.
Accelerate Smoothly — Aggressive acceleration and hard braking can increase fuel consumption by up to 30%. Gradual speed changes keep your engine in its most efficient range.
Reduce AC Usage at Low Speeds — Air conditioning puts extra load on the engine. At city speeds, rolling down the windows can save noticeable fuel over a long drive.
