2000 civic poor gas mileage
I have a 2000 Civic Ex 70k that is getting approx. 24 MPG for about 60
highway/ 40 city driving.
I recently bought this car and am extremely surprised by the economy.
I drive it gently, tires are correct pressure, plugs I believe, were
changed around 40k at the dealer, recent oil change and air filter. It
needs an alignment, but I am not aware that this would affect the fuel
economy this drastically. I was hoping to get at least 30 mpg. Anyone
have this problem before? Thanks

We don't know it you're talking Imperial or US MPG, and is it 70,000
Kilometers or miles? I might suggest you have winter gas where you are,
but we don't know where you are.

there's a ton of reasons why. need to be more specific. things to look
into include brakes binding, dying oxygen sensor, bad plug leads, wrong
oil grade, ignition timing, leaky injectors, etc. my 2000 civic cx only
got about 34 mpg on the freeway, driven fastish. the ex is a little
more thirsty than that.
also, make sure you have the consumption calculation right. you need to
fill to the top, then calculate consumption from the next complete fill.
and average it over several tanks.

there's a ton of reasons why. need to be more specific. things to look
into include brakes binding, dying oxygen sensor, bad plug leads, wrong
oil grade, ignition timing, leaky injectors, etc. my 2000 civic cx only
got about 34 mpg on the freeway, driven fastish. the ex is a little
more thirsty than that.
also, make sure you have the consumption calculation right. you need to
fill to the top, then calculate consumption from the next complete fill.
and average it over several tanks.
