How can I improve my Toyota Highlander's fuel efficiency?

I recently purchased a Toyota Highlander and I am concerned about the fuel efficiency. I drive mostly in the city and have noticed that I am getting lower gas mileage than the advertised average. Is there anything I can do to improve the fuel efficiency without sacrificing performance?

One of the easiest ways to improve fuel efficiency is by making sure your tires are properly inflated. Under-inflated tires can cause your car to work harder, thus using more fuel. You can check your tire pressure at any gas station or purchase a tire pressure gauge for convenience.

Another thing you can do is to make sure you are using the correct grade of gasoline for your Highlander. Higher octane gas is not necessary for most cars and could actually be causing you to use more fuel. Stick to the recommended octane level for your vehicle to save money on gas.

If you tend to sit in traffic a lot, try turning off your engine instead of idling. This can help save fuel and also reduce emissions. Just remember to turn off your car completely, including the air conditioning, to see the most savings.

Changing your driving habits can also greatly impact your fuel efficiency. Avoid rapid acceleration and constant braking, as this can use up more fuel. Instead, try to maintain a consistent speed and use cruise control when possible.
