Hi, i have a 08 Civic 4dr with 1.8 and AT.
My civic has always drank a lot of gas since i got it like between 10.5 and 11.7L/100 i think its a bit excessive since i don't always stay in city or floor it.
I recently changed the serpentine(was due since cracked), air filter and spark plugs and did the oil change when it was due.
The car currently have 255k kilometers and no light in the dash. Any solution to have better gas mileage? I did like 312Km on 36Liters.
My 03 accord with v6 always floored had like 10L/100 something is probably wrong with this civic and im trying to find what.

Thanks
