I swapped 1nzfe auto tranny on my corolla 2002 almost four years ago and the mileage has always been horrible. Anyways, on the way to islamabad I filled up my car’s tank with 45 litres of petrol and half tank is already consumed (Kallar Kahar)
Keep in mind that only one person was travelling i.e Me so the car was low on weight and there was no use of AC. New spark plugs were installed before taking it on long route, oil/air filter original have been used always. Changed car’s oil with helix hx3 last week. The car is giving poor mileage, any suggestions or reference to experts who can solve this problem would be appreciated.
As for the sensors, all I know is O2 sensor is working fine.
Also, the car has four gears only, that might be a factor too. Picture has been attached of speedometer of car on 120km/hr.
