How do I maintain the engine of my Ford Galaxy?

I recently purchased a second-hand Ford Galaxy and I want to ensure the engine stays in top condition. Are there any specific maintenance tasks I should be doing?

Regularly check and change the engine oil as recommended by Ford. It helps to keep the engine running smoothly and extends its lifespan.

Make sure to check and replace spark plugs if needed. They play a crucial role in starting the car and overall engine performance.

Don't forget to check the air filter and replace it when necessary. A clogged air filter can decrease engine power and fuel efficiency.
