What kind of engine oil should I use for my Ford Focus?

I recently purchased a Ford Focus and I want to make sure I'm using the right engine oil. What type and brand of engine oil do you recommend for this car?

I've been using Castrol EDGE in my Ford Focus for the past 5 years and it has been performing great. I would definitely recommend it.

I always use Mobil 1 in my Ford cars and they've never given me any problems. Definitely a trustworthy brand.

I would suggest using Valvoline Advanced Full Synthetic oil. It meets all of the Ford's requirements and provides great protection for your engine.
