What is the best way to maintain the durability of a Toyota Land Cruiser's engine?

I recently purchased a Toyota Land Cruiser and I want to make sure that the engine stays in top shape for as long as possible. What measures can I take to maintain the engine's durability and prevent any major issues?

Regular oil changes and tune-ups are crucial for keeping the engine in good condition. Make sure to follow the recommended maintenance schedule provided by Toyota.

Avoid overloading the vehicle and driving at high speeds for extended periods of time. This can put unnecessary strain on the engine and lead to premature wear.

Invest in high-quality fuel and make sure to use the recommended octane level for your Land Cruiser. Low-quality fuel and using the wrong octane can cause damage to the engine over time.
