What are the reasons for the high fuel consumption of the Corolla 1.6?
2 Answers
The main reasons for the high fuel consumption of the Corolla 1.6 lie in daily maintenance, such as not replacing the air filter, fuel filter, engine oil and oil filter for a long time, abnormal tire pressure, or not replacing spark plugs according to the maintenance cycle. Maintaining good driving habits can also effectively reduce the problem of high fuel consumption. Notes: 1. Driving habits: Parking and idling consume a lot of fuel, so try to minimize idling time. Poor control of low-speed gear shifting will not save fuel. Driving in low gear for a long time will also increase fuel consumption, and frequent lane changes and curved driving will increase fuel consumption. Therefore, avoid driving at low speeds for too long, as engine failure can also cause abnormal fuel consumption. 2. Engine oil type: There are strict requirements for engine oil types, as the performance and technology of different engines determine which type of engine oil to use. Using the wrong type can lead to increased fuel consumption, abnormal wear, and other issues.
When I drove the Corolla 1.6, the sudden increase in fuel consumption was a headache, mainly caused by driving habits. On the road, I often accelerated sharply or braked suddenly, forcing the engine to work harder and consume more fuel; driving over 120 km/h on the highway increased wind resistance, which also wasted fuel; frequent stop-and-go traffic in the city led to prolonged engine idling, burning fuel inefficiently. There were also car condition issues, like underinflated tires increasing rolling resistance—I had to check tire pressure monthly; or a dirty air filter restricting airflow, which could be replaced every six months to save fuel. As for fuel quality, using low-grade gasoline to save money resulted in incomplete combustion, requiring more fuel; neglecting maintenance for long periods led to worn-out spark plugs causing poor ignition and higher fuel consumption. I recommend adopting a smooth driving style and performing regular simple checks, such as cleaning the throttle body, to reduce trips to the gas station each month.
