Which grade of oil should I use in my Ford Fiesta Zetec?

I have a 2012 Ford Fiesta Zetec 1.25 that doesn't have start-stop technology.

The manual says get Castrol Magnatec professional a5 5W-30. But this is no longer available. There is a start stop version. Would this be the best thing to use or something else?

5W-30 is the grade of oil you need and it must be fully synthetic, ideally from a known brand such as Shell, Castrol or Mobil. The rest of it is largely marketing. Castrol makes lots of noise about a special molecule used in the stop-start version of the oil because of the potential for increased wear. As such this will be plenty good enough to serve as the oil in your Fiesta.
