Estimated Total Trip Cost (මුළු ගමන් වියදම)
115 km total • 8.21 Litres required
The same 115 km journey driven in an Electric Vehicle (EV) consuming ~6 km/kWh charged overnight at CEB's off-peak tariff (Rs. 17/kWh) would cost approx. Rs. 926, saving Rs. 2,227 compared to petrol!

Optimal Tire Pressure
Under-inflated tires by just 3 to 5 PSI increase rolling resistance and reduce fuel economy by up to 5%. Check tire pressures weekly on cold tires according to the driver door frame sticker.
Smooth Acceleration & Coasting
Jackrabbit starts and sudden braking in urban traffic waste enormous amounts of fuel. Anticipate traffic flow, accelerate smoothly, and allow vehicle momentum to coast to stops.
Air Conditioning Management
In heavy stop-and-go city traffic, the air conditioner compressor can consume 15% to 20% of engine power. Keep interior temperatures set comfortably without freezing blower settings.
Fuel Pricing, Highway Tolls & Mileage in Sri Lanka (ඉන්ධන සහ ගමන් වියදම්)
Fuel prices in Sri Lanka are revised periodically by the Ministry of Power & Energy in accordance with the national fuel pricing formula:
- Petrol 92 vs 95 Octane: Standard Japanese, Indian, and domestic passenger cars (Alto, Wagon R, Aqua, Vitz) run optimally on 92 Octane. Premium 95 Octane is only needed if mandated in your vehicle's engine manual.
- Expressway Toll Fees (Category 1): Standard light vehicle tolls are Colombo ↔ Galle (E01) Rs. 600, Colombo ↔ Matara (E01) Rs. 800, Airport Expressway (E03) Rs. 350, and Central Expressway (E04) Rs. 400.
- Carpooling Economy: Splitting fuel and toll costs across 3–4 colleagues or family members reduces personal travel expenses by over 60%.
