chohdry pai, tussi civic naal ek kam hor v kra lo, apni gas kit ki saari wiring joints, fuses aur grips check krwa lo, balke saaf krwa lawo to ensure perfect current flow. Agar possible ho to cng kit ki ground wiring b krwa lain with moti zero gauge pure copper wire.
aapki car ki per cylinder mileage kaafi improve ho jaye gi, upto 150kms per cylinder on long route.
Plus one thing more, I see u actually waste fuel while trying to hypermile ur car, I suggest k mileage k baarey me khof zadda (paranoid) rehna chor dain. drive normally, smoke corollas, keep an average speed of 100kph on highways, accelerate normally on roads instead of dragging ur car like a mehr khan on road for less fuel consumption.
I do the same with my city idsi and exi civic and believe me I am more than happy with both of them. Kal bhi city ko 140kph pr khich k rakha and she gave me 175kms on highway with full ac. exi in same conditions in khicho khich driving gives 140-160kms with ac easily.
agr abi mileage achi na b ho to at least I am not sad or gloomy k itni ehtyaat bhi ki and mileage b nai milli.
ek tanki is mashwre pr b jala kr dekh lain, I am sure aapi car still 100kms+ he day gi in full fill.
