How can I increase gas mileage in my Toyota Highlander?

I'm looking for tips or modifications that can help me improve the fuel efficiency of my Toyota Highlander. Can you offer any suggestions or advice?

One simple way to improve gas mileage is to keep your tires properly inflated. Under-inflated tires can increase drag and decrease fuel efficiency. Additionally, using cruise control on highway drives can help maintain a consistent speed and save gas.

Installing a cold air intake or a high flow air filter can also improve gas mileage by allowing more air flow into the engine. This can result in better combustion and improved fuel efficiency.

Another way to increase gas mileage is to drive more efficiently. This means avoiding sudden accelerations and hard braking, which can waste fuel. By maintaining a steady, moderate pace and anticipating stops and starts, you can save gas and money.
