How to maintain engine performance in a Ford Ranger?

I recently bought a used Ford Ranger and I want to make sure the engine runs smoothly. What should I do to maintain its performance and prevent any potential issues?

Regularly change the engine oil and filter at recommended intervals. This will keep the engine clean and prevent build-up of harmful deposits.

Check the air filter every 12,000 miles or once a year. A dirty air filter can restrict airflow and decrease engine performance.

Inspect and replace spark plugs as recommended by the manufacturer. Worn out spark plugs can cause misfires and decrease engine performance.
