What is the best way to maintain the durability of my Ford Transit Custom's engine?

I recently purchased a Ford Transit Custom and I want to make sure I am properly maintaining the engine to ensure its longevity. What steps should I take to keep the engine running smoothly?

Regular oil changes and using the recommended type of oil for your specific engine is key. You should also check and change the air filter regularly to prevent buildup and allow for proper air flow.

Make sure you are using the right fuel and not using low-quality or contaminated fuel. This is crucial to prevent any damage to your engine and improve its performance.

Keep an eye on your coolant levels and regularly check for any leaks. A lack of proper cooling can cause major damage to your engine, so it's important to address any issues immediately.

Regularly inspect and replace worn out belts and hoses. These parts are crucial for the proper functioning of your engine and should be replaced at the first signs of wear.
