How can I improve my gas mileage in my Toyota Highlander?

I recently purchased a Toyota Highlander and I've noticed that I'm not getting the best gas mileage. Are there any tips or tricks I can try to improve my gas mileage?

One way to improve your gas mileage is to make sure your tires are properly inflated. Underinflated tires can reduce your fuel efficiency.

Another tip is to avoid idling for long periods of time. If you're stuck in traffic or waiting for someone, turn off your engine to save on gas.

Consider using a fuel cleaner or additive to help improve your gas mileage. This can help remove any buildup or deposits in your engine.

One lifestyle change that can improve your gas mileage is to try and consolidate your errands and trips. This will reduce the amount of driving you do and can save on gas.
