What are some maintenance tips for the Ford Ranger engine?

I just bought a Ford Ranger and want to make sure I keep the engine in great condition. What are some recommended maintenance tasks for the engine and how often should I perform them?

It's important to regularly check the engine oil levels and change the oil every 5,000 miles or 6 months, whichever comes first.

Check and replace the air filter every 12,000 miles or if it looks dirty. A dirty air filter can reduce engine performance and fuel efficiency.

Inspect and replace spark plugs every 30,000 miles or as recommended by your mechanic. Worn spark plugs can decrease engine power and fuel efficiency.

Adding a fuel additive every 5,000 miles can help prevent buildup of deposits in the fuel system and improve performance. Make sure to use a product specifically designed for your Ford Ranger.
