What type of oil should I use for my Ford Focus?

I recently bought a used Ford Focus and I'm not sure what type of oil to use for my car. Should I use conventional oil, synthetic blend, or full synthetic oil? I want to ensure the best performance and longevity for my car.

As a mechanic, I would recommend using a full synthetic oil for your Ford Focus. It offers the best protection and performance for your engine.

I've been using a synthetic blend for my Ford Focus for years and haven't had any issues. It's more affordable than full synthetic but still offers good protection.

Conventional oil is the cheapest option, but it may not provide adequate protection for your car. If you can afford it, I would stick with full synthetic.
