What is the best oil to use in a Ford Focus RS?

I recently purchased a Ford Focus RS and I'm wondering what type of oil I should use for optimal performance. It's important to me to have the right oil that will keep my engine running smoothly and prolong its lifespan. Any recommendations?

I would recommend using a high-quality synthetic oil, such as Mobil 1 or Castrol Edge. These types of oil will provide the best protection and performance for your engine.

I have been using Royal Purple in my Ford Focus RS and it has been great. It's a fully synthetic oil that is specifically designed for high performance engines.

Stick with the recommended oil type by Ford for your Focus RS, it's always best to follow the manufacturer's guidelines for optimal performance and engine longevity.
