I feel like I'm getting much lower gas mileage these days. on 2007 Honda Fit

Had my 07' since 06', bought it when they just came out. I feel like my gas disappears a lot faster these days. Is that just the ethanol or do I need a flush or cleaning?

have your sparkplugs checked.carbon might have accumulated in its tip causing fuel to burn slowly.remove those carb depo by scraping it off..that might help
