What is the recommended oil for a Ford Focus ST?

I just got a Ford Focus ST and I want to know what type of oil is recommended for it. I want to make sure I am using the right kind of oil for optimal engine performance and longevity.

For the Ford Focus ST, it is best to use a high-quality synthetic motor oil. Look for an oil with the API 'SN' rating for gas engines.

I always use Royal Purple 5W-30 in my Ford Focus ST and have had great results. It's specifically designed for high-performance engines.

Make sure to check your owner's manual for the exact oil recommendation for your specific engine.
