How to improve gas mileage for my Toyota Hilux?

I recently purchased a Toyota Hilux and I'm looking for ways to improve its gas mileage. I've heard that new air filters and regular tune-ups can help, but what else can I do? Any tips or suggestions would be greatly appreciated.

One of the most effective ways to improve gas mileage is to regularly check and replace your air filter. A dirty air filter can limit airflow to the engine, causing it to work harder and use more fuel.

Also, make sure to keep your tires properly inflated. Underinflated tires can increase rolling resistance, which can decrease your gas mileage.

Another tip is to avoid idling for long periods of time. If you know you'll be stopped for more than a minute, it's better to turn off your engine and restart it once you're ready to go.
