High travelling speed - i.e. 140+ on highway
High revving in gears
Old engine needs tune up - use some seafoam or fuel injection cleaner kit.
I had the same issue. I was getting more or less 550 to 600 then often I got 500. After another seafoam, oil change and a stiff engine mount, gas mileage went up.
Right now I am getting roughly 15km per liter.

i could see getting better milage after a tune up but you would thing it would be a gradual loss in milage and not a sudden 100-150 km loss . but you probably know more than me. any other suggestions or is nova_dust fairly accurate

How do u guys get that much on a Honda civic? Are those like basic non v-tec engine? I have all si engines at home and the most i got was 400km. Not even close to 600km mark per tank. Maybe because i drive automatic and v-tec and also i give it a lot of rev all the time haha.

I would say Nova is probably correct. Reason being, you want to fix the least expensive things first to see if that fixes the problem. A tune-up and using some seafoam would be the first on the list. Check you tire pressure, and remove any unnecessary added weight to the car. Like heavy objects in you trunk.
