What is the best way to increase the fuel efficiency of my Toyota Highlander?

I recently bought a Toyota Highlander and I noticed that it consumes a lot of fuel. Is there anything I can do to increase its fuel efficiency without compromising its performance?

Regular maintenance and tune-ups can greatly improve your vehicle's fuel efficiency. Make sure to follow the manufacturer's recommended maintenance schedule.

Change your driving habits. Avoid aggressive driving, excessive idling, and using the air conditioning unnecessarily.

Consider investing in a fuel efficiency chip for your vehicle. These can improve gas mileage by optimizing the engine's performance.
