Frequently Asked Questions
Why does L/100km increase when fuel efficiency is worse?
L/100km is an inverse measure — lower is better. A car using 5 L/100km is more efficient than one using 12 L/100km. When converting to mpg, higher mpg means better efficiency.
What is the difference between US mpg and Imperial mpg?
A US gallon = 3.785 litres, while an Imperial gallon = 4.546 litres. So Imperial mpg is about 20% higher than US mpg for the same fuel efficiency. A car rated 40 US mpg = 48 Imperial mpg.
What is a good fuel efficiency for a car in Nigeria?
Most Nigerian cars get between 8–14 L/100km (roughly 17–30 mpg). Smaller cars like Toyota Corolla may achieve 7–9 L/100km. SUVs and older vehicles typically use 12–18 L/100km.
How do I convert km/L to L/100km?
Divide 100 by your km/L value. For example, 12 km/L = 100/12 = 8.33 L/100km. These two units are inversely related.
How is km/L used in Nigeria?
Nigeria commonly uses km/L or "litres per 100 km" to discuss fuel economy. At ₦1,200/litre, knowing your L/100km helps estimate fuel costs per trip.
