Alot of the basic eco tips work on hybrids like regular cars. Inflating tires to max sidewall psi, driving the speed limit or slightly slower. Taking the highway vs city, hovering around 45-55 mph. Riding brakes to a stop to get all the regen you can. Try buying gas at different stations as they vary in ethanol and octane. We find BP and shell gives the best mpg, sometimes as much as a 5 mpg difference even on regular octane.
Not knowing everything about your cars service history, a bad starter battery can caused low ima performance, random check engine lights and low mpg. You can and should replace it with a group 51 that the civic uses. The cvt fluid should be changed with the first engine oil change, then every other engine oil change. Engine oil should be changed once a year or 10 thousand miles. Brake fluid should be change every 2-3 years.
