What is the best way to maintain a Ford Focus's engine?

I just bought a used Ford Focus and I want to make sure I properly maintain the engine for long term use. What are some specific steps I should take to keep it in good condition?

Regular oil changes and keeping up with routine maintenance is important for the longevity of your engine. I also recommend using high-quality synthetic oil to help protect the engine from wear and tear.

Another key factor in maintaining your Ford Focus's engine is to drive it responsibly. Avoid aggressive acceleration and excessive idling, as these can cause unnecessary strain on the engine.

In addition to regular maintenance and responsible driving, using fuel injector cleaner every 5,000 miles can help keep your engine running smoothly and efficiently. It's a simple and inexpensive way to prevent build-up and maintain fuel economy.
