How to Solve High Fuel Consumption in Corolla?
1 Answers
Excessive engine carbon deposits are a major cause, primarily due to the use of unsuitable fuel. This includes carbon buildup in the engine combustion chamber and intake ports. The oxygen sensor mainly monitors the air-fuel ratio of the engine. Once damaged, it can cause an imbalance in the air-fuel ratio, leading to a sudden increase in fuel consumption. During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly.
