Salam dear fellow members,
I have Civic Dec 2005 EXi Manual. It is very carefully kept car in original condition. A problem I have noticed that the car's high fuel consumption. I have recently done necessary tune ups like, got plug changed, oil, oil filter, air filter, throttle body, injectors cleaned and tappets etc. It was on CNG for quite some time but for last 3 years I have uninstalled the cylinder so no extra weight. Moreover, it has tyres 195 65 15 the only thing which is not stock. but still it should not make fuel consumption near about 7 to 8 Km with A/C in local. Its only driven local but on long route it hardly gives 10. One more thing I have noticed is higher RPM, like at 80 Km RPM is 3000 and on 5th gear at 120 Km/hr the RPM goes 4000.
So guys any suggestions wat could b probable cause of higher fuel consumption?
Regards,
