I know k apki post kafi purani hogai hai but men apna experience share karna chahta hun.. I have nissan clipper model 10 or 15 ki import start mn to sub thek tha but before covid gari ki mileage bohat kam hogai 8 liter pr srf 60 km chal rahi thi mene apne tor pr research ki.. or sub se pehle catalytic converter or oxygen sensor clean karwaya (engine k exhaust pipe k sath or silencer se pehle catalytic converter laga hoa hai) 2nd gari k fuel injector clean karwaye 3rd is k original spark plug lagwae (ek plug mujhe 1500 ka mila iridium plug) 3no plug change karne k bad throttle clean ki or last men zic ka 20 50 oil dala is se na srf gari bohat halki hogai balke bridge pr b speed down nahi hoti. ab ALLAH ka shukar hai mileage bohat behtar hogaii hai in city 12 se 15 W/O ac or long pr aprox 18 tk.. note : clipper k sath rogh drive kabhi nhi karen is se gari ka fuel average kharab hoga
