Bhai meray Civic ko CNG p chalana waisay hi bura lagta hai.
Either drive it on good quality petrol, or if you wanna drive it on CNG, sell it and buy Mehran, Santro, Cherry QQ, etc.
(No offense / disrespect. Just wanted to say that if you own a handsome and beautiful ride like Civic, you must also manage to afford it and drive it on good fuel)
