Worked example
50 L capacity, 10 L reserve and 10 L/100 km gives 400 km usable range. A full-start 600 km trip needs one theoretical refuel; 400 km needs none.
Method
Usable full-tank range = (tank capacity − reserve) ÷ litres per 100 km × 100. Use starting fuel instead of capacity for the first leg, then round the additional full-tank legs up to fuel stops.
Limits
Starting fuel must be between the reserve and tank capacity; capacity must exceed the reserve and consumption must be positive. Real consumption and station availability are not checked. Your chosen reserve is not a safety recommendation.
