What is the best way to increase gas mileage in my Toyota Highlander?

I just bought a new Toyota Highlander and I'm looking for ways to improve its fuel efficiency. Is there anything specific I can do, such as changing my driving habits or adding certain accessories?

The best way to improve gas mileage in your Toyota Highlander is to make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency by up to 3%. Additionally, try to avoid aggressive driving and use cruise control on the highway to maintain a steady speed.

You may want to consider investing in a fuel economy chip or a high-flow exhaust system. These accessories can help optimize your Highlander's performance and increase gas mileage.

Another thing you can do is regularly maintain your Highlander, including regular oil changes and replacing air filters. This will keep your engine running efficiently and improve gas mileage.
