juz wondering do u guys go JB with less than 3/4 tank? or u guys "hiong"???

coz i was thinking if i follow law and go in with 3/4 tank full, then can only pump abt 10L at most. can't seem to save much $$$ ley. somemore my fuel meter not accurate, from full to 3/4 mark drops very fast, only travel about 90km+
