Question about 2007 Toyota Corolla
Clean the mass air flow sensor located just after the air filter...There are special cleaners but I think a home drycleaner should help but delicately applied ..I used a feather initially..Also some carburetoor cleaner and new spark plugs should help double that value of km/l

A dirty air cleaner will cause an engine to use lots of fuel and still appear to run fine especally in cold weather. If you have not changed your air cleaner in sometime do so and note the difference.
Also a sticking EGR valve i.e stuck closed at highway speeds / passing / starts and stops can rob you of fuel economy.
If you know any half way good backyard auto mechanics they will know how to test an EGR valve with an external vacuum hose.
Thanks for using FixYa!

Testimonial: "Thanks a lot. Already changed air filter but problem persists. Shall have to check the EGR valve by mechanics. Thanks again."
The fuel filter is located in the fuel tank. TO access it, remove the rear seat, and remove the access panel to expose the top of the tank. Remove the top seal, and the whoe assembly comes out as a unit.
