How much does fuel consumption decrease if you reduce your speed from 110 km/h to 100 km/h?

Reducing speed from 110 km/h to 100 km/h decreases fuel consumption by 10%.

To minimise fuel consumption, it is very important that you not drive at excessive speeds. The faster you drive, the more air resistance there is. This leads to an increase in fuel consumption.
