I have a 2003 Civic EX with 1.7L VTEC.Tires are P185/15R65 and on my
last reading I got 33.1 mpg averaging 80mph on the interstate
freeway........27.1 in city driving (last time I could check for
predominantly city driving 2 months ago).I drive mostly interstate
freeway and use the cruise control locked on 80mph whenever can.
