Why is my Toyota Corolla's fuel economy decreasing?

I've noticed that my Toyota Corolla's fuel economy has decreased significantly over the past few months. Could there be a specific issue causing this and how can I improve it?

It's possible that your car's air filter needs to be changed. A dirty air filter can affect fuel economy. Also, check your tire pressure and keep it at the recommended level to improve gas mileage.

There may be an issue with your spark plugs or fuel injectors. It's best to bring your car to a mechanic for a tune-up to ensure everything is running smoothly.

Another factor that can contribute to decreased fuel economy is driving habits. Avoid excessive idling, accelerating quickly, and braking harshly. This can all use more gas.
