If youre experiencing poor mileage with your Toyota Yaris, there are a few key maintenance tasks and adjustments that could help improve fuel efficiency. Start by ensuring that the air filter is clean, as a clogged air filter can restrict airflow to the engine, reducing fuel economy. Replacing old spark plugs o r ensuring they are in good condition can also help with efficient combustion. Keep an eye on tire pressure, as underinflated tires can lead to increased rolling resistance and reduced fuel efficiency. Additionally, make sure to use high-quality fuel and consider switching to a different oil grade if recommended for your model. Regular oil changes are essential, as dirty oil can cause the engine to work harder and consume more fuel. You might also want to inspect the fuel injectors to ensure they are functioning properly and not clogged. In some cases, cleaning o r replacing the fuel filter can improve the fuel systems efficiency. Finally, adopting smoother driving habits, such as avoiding rapid acceleration and braking, can also help improve mileage. Implementing these simple fixes can make a noticeable difference in your Yariss fuel efficiency.
