Standard is 60km for standard driving @ optimum of 60km/h-80km/h.... but depends on driving style la...
if "E" still vroom vroom.... 20km already finished lo....

also depends on age of car... normally older car will have some water in tank, then cannot last till 60km lo.... or sensor rosak....

Advice, as long as it hit "E", try fill up within 30km of range...
