Hi, my car is burning more gas then usual
from one full tank im getting 300 - 320 km, but i should be getting around 400
whats wrong with my car? or is it just the fact that its getting old
btw it has 214XXX kms on it, automatic! thankss

do u know the km's when the

-fuel filter
-air filter
-o2 sensor
-spark plugs

were changed?

btw if u drive with a heavy foot 300-320 km is pretty reasonable

no im not too sure. . sometimes i drive with a heavy foot not all the time though

could be a lazy o2 sensor. could be timing. could be plugs. so many variables.
first thing most places will do is start with a tune up, if it needs it

alright thanks, ill go get it checked out
