How can I increase my Toyota Hilux's fuel efficiency?

I've noticed that my Toyota Hilux is consuming more fuel than usual. What can I do to improve its fuel efficiency?

Check your tire pressure regularly. Low tire pressure can cause your vehicle to use more fuel. Make sure they are properly inflated to the recommended level.

Change your air filter regularly. A dirty air filter can decrease your fuel efficiency by up to 10%. It's an easy and inexpensive fix.

Avoid driving at high speeds and accelerating aggressively. This can have a big impact on your fuel consumption. Try to maintain a steady speed and use cruise control when possible.
