i have a 1993 civic Ex coupe 5spd
147xxx miles
lowered 1 inch
16 inch "light" rims<--dunno exccatly how light
only in the back
donuts in the front
box with 2 10 inchsubs and amp in the trunk
spark plugs changed recently
exhaust leak from b pipe

im currently gettig about 220 or less miles wiht a full tank

how much are you guys getting, what cars? am i supposed to be getting more? iknow exhaust leak kills and i hav to change fuel filter and stuff but how bad is my mileage? how much should i be getting?

 

I've got a bad exhaust leak that I've been too lazy to fix, and I still average 37MPG+ 94 DX Hatch w/ D15B VTEC.

 

i get low 30's in my 99 hatch mainly city driving. its basically stock with basic bolt ons and a tranny swap. i'd think you should be doing better than 220 a tank, time for a tune up?

Same thing for me, same car, everything. You should be getting more than 220 per tank, but look of it as MPG rather than miles per tank. Everytime you fill up, just calculate MPG from the miles on the trip meter to the gallon you put in.

 

I've got a '95 Ex... I was having the exact same problem as you for a couple tanks... Only getting 220 - 240 per tank. I simply changed the plugs and o2 and it jumped back up fast. Also, have you checked the inner walls of your intake manifold? Wipe a finger in there, if it comes out black (which it probably will) grab some carb cleaner and go to town. Hope that helped.

 

Ive got a 93 hb vx w/ a d16z6 and it gets 44 mpg. intake & catback exhaust
its the best commuter car ever
