i just calculated the mpg for my last tank full of gas. its a 1990 integra rs, recent tuneup, no a/c or p/s, a little weight loss, 2.5 catback and 50 psi in my 195/60/14s. i was pleasantly suprised when i got 37.01 mpg. it was almost 100% highway @ 65-70 mph. does this seem on par with others expieriences?? i did it about a month and a half ago and got about 35 so i guess im pretty consistent

 

oops sorry i justed search and saw the mpg thread

 

watch out for unusual tread wear

 

I get 33 mpg in my 97 gsr with stock 15's bolt ons, and some internal mods, doing 65-70 on the freeway. 37 mpg would save me almost $100/month since I drive 100 miles/day to work.
