AoA. Guys I need help. I dont know much about cars but I've put in quite a lot of money in mine.I have a 96 exi honda civic 1500cc with stock engine.got it in 1996 "zero meter" now 174000 driven. Mosly local in abbottabad. Its giving me an average of as low as 5km/lit now! Without AC local pe.Was previously on gas for many years but got the gaskit removed this February after which it's been on petrol. In april did a few modifications from peshawar. Downpiping, (prolly 2 inch pipe),meganflow exhaust, "kabli" air intake (removed the original filter and resonator box) iridium spark plugs. On the way back n till recently, it was doing okay but since two months its been a menace on consumption. Got the mobile oil changed, spark plugs removed n put in the normal ones. Checked the throttle body and the MaP ans TS sensors , they seem to b fine. The car's not giving off any smoke. Before doing the mods I read here on the forums these mods dont make quite a difference on the consumption but the mechanics here in abbottabad say its cuz of the air filter and exhaust. And its not been abt 400 kms since i changed the mobil oil and yesterday it had about half a litre less. Kam kr rhe ha oil ...is it the engine ? Confused . Need help. Wil b grateful
