The car has 94000kms, and it use to get over 600kms to a tank, but now I only get around 400kms. Can anyone help?
have you moved recently or changed jobs where you have to drive further? my sunfire uses a lot of gas on short hops but my milage almost doubles when i take long trips.

you need a tune up or you have a leak in your gas tank

Have u replaced the air filter or fuel filter? Did you ever have
a fuel injector flush ? or tune up. it all matters.

This is a huge change. You may have a leak but check these:
Tank dented in – holds less fuel.
Dirty or clogged air filter- engine runs rich
Emission system malfunction
Fuel injection malfunction
Low tire pressure – increased rolling resistance
