How much oil does your 6th Generation get through?? Mine seems to use up quite a lot. My last Civic never needed topping up but my Accord Sport seems to be rather thirsty. There are definitely no leaks anywhere, i've had all oil changes done at Honda and i put in the same oil they use for the changes, mobil super 3000 formula FE. Are they just a bit thirsty for oil or do you think there is an issue??
