1. Calculate Fuel Volume
Divide total kilometres traveled by your vehicle's average mileage (Distance ÷ km/L).
Ensure tire pressure is at manufacturer spec to prevent up to 5% mileage drop.
2. Carpool Cost Splitting
Divide total fuel expenditure and highway tolls equally among all passengers traveling together.
Fair cost-sharing eliminates confusion at the end of weekend trips.
3. FASTag Tolls Factored
Expressway toll charges often add 15%–25% to overall travel cost on modern highway corridors.
Factoring tolls in advance gives a realistic per-person budget.
Frequently Asked Questions
How does air conditioning affect fuel economy?
Running the AC in city traffic typically reduces fuel mileage by 5% to 15%. On expressways at high speeds, driving with AC on is actually more aerodynamic than keeping open windows, which creates heavy drag.
What is the optimal speed for maximum fuel efficiency?
Most passenger vehicles achieve peak fuel economy in top gear between 70 km/h and 85 km/h. Exceeding 100 km/h rapidly increases wind resistance, burning up to 20% more fuel.
