My toilet was installed in roughly speaking 1995, and has a half and full flush. Was wondering how oodles litres it used for each?

Thanks.
Answers:    An old style single flush toilet can use up to 13 litres of river
in one flush. New, more water-efficient dual-flush toilets use only six litres for a full flush and four litres near a reduced
flush.
for a full flush it's about 1.6 gallons i think 2 litre,,
