Reference fuel prices in Saudi Arabia
91 and 95 octane gasoline are government price-capped and have been fixed since July 2021 (price ceiling policy), while diesel prices are reviewed annually. Enter the current price you know to ensure accuracy, since this calculator doesn't assume a fixed price on your behalf.
Estimated carbon emissions are calculated with a near-fixed scientific factor (~2.31 kg CO2 per liter of gasoline burned, ~2.68 kg per liter of diesel) — this is a scientific constant that doesn't change, unlike the price which changes periodically.
FAQ
What's the difference between "liters/100 km" and "km/liter"?
"Liters/100 km" measures how many liters your car uses every 100 kilometers (the most common in car specifications). "km/liter" measures how many kilometers you travel on one liter. Choose whichever unit you know from your car's manual.
Is the reference price always accurate?
91 and 95 octane prices are capped and relatively fixed, but it's best to verify the latest announced price via the Saudi Aramco website before relying on a precise number for an important financial decision.
