How do I properly maintain the engine of my Toyota Camry?

I've been driving my Toyota Camry for a few years now and I want to make sure I'm properly maintaining the engine for longevity. I'm not very knowledgeable about cars, so what are some tips and tricks to keep my Camry running smoothly?

The key to maintaining your Toyota Camry's engine is regular oil changes. Make sure to follow the manufacturer's recommended oil change interval and use high quality oil. Additionally, check your oil level and top it off if needed.

Don't forget about your air filter! It should be changed every 15,000 miles or as recommended by the manufacturer. This will improve your Camry's fuel efficiency and prolong the life of your engine.

Another important tip is to use high quality gasoline and avoid filling up with low quality or contaminated fuel. This can cause engine problems down the road.
