Is 10 MPG good?

As US MPG (23.5 L/100 km): very thirsty. That is very heavy fuel use, typical of large V8s, vehicles that are towing, and light trucks.

As UK MPG (28.2 L/100 km): very thirsty. That is very heavy fuel use, typical of large V8s, vehicles that are towing, and light trucks.

A rough guide for passenger vehicles. Real-world use varies with driving style, speed, load and conditions, and is often higher than official test figures.

How to convert 10 MPG to L/100km and km/L

Divide a fixed constant by the MPG figure. The constant is the litres in one gallon, divided by the kilometres in one mile, multiplied by 100.

US: 235.215 ÷ 10 = 23.52 L/100 km

UK: 282.481 ÷ 10 = 28.25 L/100 km

For kilometres per litre, multiply instead: US MPG × 0.4251 = km/L, so 10 US MPG = 4.25 km/L. For UK MPG use × 0.3540, so 10 UK MPG = 3.54 km/L.

Based on 1 mile = 1.609344 km, 1 US gallon = 3.785411784 L and 1 imperial gallon = 4.54609 L (NIST definitions).
