What's the best way to improve fuel efficiency in a Toyota Land Cruiser?

I just bought a Toyota Land Cruiser and I love it, but the fuel efficiency is not great. I'm looking for tips and advice on how to improve it without sacrificing performance.

One way to improve fuel efficiency is to keep your tires properly inflated. Underinflated tires can decrease your gas mileage by up to 0.3% for every 1 psi drop in pressure. Be sure to check your tire pressure regularly.

Another tip is to clean or replace your air filter regularly. A dirty air filter can decrease fuel efficiency by up to 10%. Consider replacing your air filter every 12,000-15,000 miles.

You can also try changing your driving habits to improve fuel efficiency. Avoid sudden accelerations and braking, as this wastes fuel. Also, try to maintain a steady speed on the highway instead of constantly speeding up and slowing down.
