Honda Car Forum

I used to get 25 mpg in city driving, and 30 mpg on the highway.
Suddenly the mileage went down to 18 in city driving. I tried fuel
injector cleaner but that did not help. Any ideas would be
appreciated.

I assume the car is still running "seemingly" well still. If its running
well still, my guess it is an external change.

-- In the cold weather, have you been letting the car sit and idle to warm?
-- When the car is cold, do you drive it hard?
-- Any other changes to your driving pattern?
-- new gas station?
-- Are the tires inflated to the correct pressure?
-- Do you keep going to the exact same gas pump? Some pumps "click-off"
sooner than others. Which would lead you to believe that the tank is at its
normal capacity, when it is really less a gallon.
