What on earth
I own a 2000 civic EX no swap
It's rated for 35 originally
that site fuel economy.gov said 32
JUST the other day i hit 41 mpg
Right now I'm at 210 miles and the needle is exactly on a half tank
I drive backroads mostly, like 90% of my driving, and definitely push the gas once in a while
what gas are you guys using?
Different engine. I use premium nothing else.

All this is anecdotal evidence. Let's see some logfiles here guys.............

One tank does not an average make...

I get about the same but its a 99 prelude.Almost the same year, both dohc vtec engines that take premium. Probably get a little less mpg then you though. Highest was 25 but during winter it was like 20. Mostly city driving with some highway but highway going 70-75 mph rpm hovers around 3500-4000. Pretty high for just crusing.

With my 99 si, i have gotten unto 320 miles to a tank. Then again, I am unsure if my low fuel light works, so I may be pushing the limits a little.

The Si will get poorer gas mileage because it's got more horsepower and people tend to over-rev their engines in these cars. The type of tires you have on your car will affect gas mileage too, esp. if they are the extra "sticky" ones and how much roll-resistance they have. Tire pressure will also affect gas mileage too.

Having said that, I currently own a 97 Civic Ex Coupe that gets about 36 mpg, with 95% of those miles on the highway, riding on Michelin Pilot Exalto (traction A rated) tires. I had a 94 Civic Ex Coupe prior to this which only got 26 mpg.
